[amsat-bb] SPROUT received in UK

2014-05-25 Thread andy thomas
I have submitted my report via the Sprout website. 25 may 2014 1308 utc, 
slightly later than yesterday's keps predicted.

I used an SDR receiver (FCD ProPlus )and took a screendump.

I was surprised that on replay the modulation was not afsk ie no tones heard 
-just heard the rushing noise and saw the data on the dump.  is that normal for 
gmsk? 

So I sent the sdr image file instead of the hex code - hope they find it as it 
was only possible to do this under the sstv section of thew ebsite.

[amsat-bb] A simple receive station for the kicksat Sprites

2014-02-27 Thread andy thomas
My contribution to the Sprite project is now hosted at :
 
http://kicksat.wordpress.com/support/kicksat-ground-station/

although I still need to amend the typo that sets the frequency at 437.4 when 
it should be 437.240.
 
Thanks to MJ for setting this up for me now that my personal website hosted by 
Google is full (I need to talk to them about that!).
 
In the page I have tried to set out a simple and modest station (my own!) which 
should be in the reach of a target school science teacher or similar.
 
This station received the 100mW transmitter of $50sat at a distance of 640km as 
shown on the waterfall display. Thanks to the team of $50sat for their 
inspirational project. This waterfall display and SDR receiver is needed for 
the bandwidth of the Sprite transmisison, and the aim is to record the entire 
pass for the project's database.
 
From an operator's point of view, the most important thing to notice is that 
no dongle is accurately calibrated and so you should not necessarily believe 
that the frequency you set in software is the frequency you actually get!
 
I hope this page will encourage people to try for the interception of the 
Sprirtes when they are launched shortly.

[amsat-bb] How to get a cheap handheld broadband RF preamp

2014-02-09 Thread andy thomas
This is primarily for the team getting ready for the Kicksat Sprite project but 
I am posting it on the amsat -bb as well as there may be a science teacher out 
there who may be interested.I'm not claiming it's revolutionary, but timely.


The requirement is for an inexpensive antenna-head preamp, lightweight, running 
on a battery.


I wouldn't claim it is a low noise preamp, but CATV ampifiers are available for 
under £5 including delivery from China.

I bought one in a car boot sale for a £1. It was supposed to work on mains 
electricty (220 volts!) and is therefore obviously unsuitable to use outside.

So I have taken out the mains transformer and the diode rectifier matrix and 
now run it off a 9 volt battery. I've also shown that the input and output 
sockets can be changed. This is simple soldering as even I can do it.


Obviously the same principle applies to any TV amplifier, broadband, and 
needing filtering at the antenna head. Just look to see if 435 MHz is included 
in the bandwidth.

At some point I'll design and construct an input filter.


For those who may be interested, here's a direct link to my page:

https://sites.google.com/site/andythomasorg/funcube/cheap-rf-amplifier

or you can get there by going to  http://www.andythomas.eu , choosing Funcube 
from the drop down menu and then get the page from the bottom of the Funcube 
page.

[amsat-bb] Using AO-40 in Rx for Ham TV?

2014-01-27 Thread andy thomas
I was just wondering if the AO-40 LNBs connected to a Funcube dongle (and a 
bias tee for power) would recieve the carrier (is there one on DATV) from the 
ham TV test transmisisons? 


If so, that should be a project that could show AOS/LOS , power levels etc, 
even if it's a black screen being sent: after all, it's RF.

maybe this has been thought about before? But I could use my converted blue 
lnb...

[amsat-bb] Practical note on using dongles

2014-01-18 Thread andy thomas
I've added a Funcube page (from the menu)  to my website 
http://www.andythomas.eu  describing lessons learned about using dashboard 
software etc rom the perspective of an interested science teacher using a 
dongle (rather than just using my ICOM IC-910).

I don't feel bad about admitting the problems I encountered. All project 
managers know that the  lessons learned log is the bit you wish you'd known 
before you started the project.

For those of us about to receive the Kicksat Sprites (when launched), and 
others using RTL dongles, the experience may be useful.

2013-09-26 Thread andy thomas
According to the Chinese media, China seeks a name from the public for her 
rover due to land on the Moon in December.

I would like to suggest the name of the the Chang'e Lunar rover should be Bai 
Ze or in various characters: Baí Zé 白泽


Baí Zé 白泽 is a famous figure in Chinese mythology and I think that because Baí 
Zé 白泽 knows everything about all the other supernatural beings it should be the 
name of this rover.

If anyone can find a direct email address then please can i encourage you to

[amsat-bb] Thanks for qsl card

2013-01-02 Thread andy thomas
All
 
this is just a public posting to thank the FITSAT-1 Niwaka team for their qsl 
card (number 124) acknowledging my reception of JQ6YEW, which I received in the 
post this morning.
 
In my opinion, following this tradition of ham radio proves the entitlement to 
the use of these frequencies which lie within the passbands of our transceivers.
 
I have listened for ham radio operators since 1968 and as a teenager at that 
time I sent my reception reports, seeking the goodwill of the operators. The 
thrill of QSl'ing hasn't gone away, although I am now licensed to transmit and 
hold my DXCC and Diamond DXCC on HF.
 
I wish more satellites would follow this tradition, as I am keeping my personal 
documentary record of the use of amateur satellites in this way.
 
With thanks for the card and my very best wishes to the FITSAT team

Hello Andy and Mike

It is a great CAT interface for satellites. It prevents the constant toggling 
between VFO A and VFO B while receiving, so you will have a normal reception 
without holes in the signal and it always will prevent burn the preamplifier.

I constructed the interface and made the case using an empty electric tape box. 
I have tested it on FO-29 and VO-52 and it works Excellent! I use it in my 
portable operations running half-duplex with my FT-817nd.

I have the following information from the AMSAT NEWS SERVICE
(ANS-351).

To order please send the following either by mail or email as follows:
+ Your name and shipping address
+ Phone number and email address
+ Item you are requesting
+ Enclose a check for the appropriate amount, payable to ARRL
  ETP, sent to attention of ARRL Education Services

Please contact Amy in ARRL Education Services at astrickl...@arrl.org

Knowing little about design, I just wonder if rather than deploying cubesats 
fitted as ballast, a transponder could not be fitted to the hull of the 
appropriate vessel which contains the sats and ballast? It could also relay 
vibrations from the vessel as it tumbled in the sky and would therefore have 
some utility to launch provider? I think this approach was adopted by Aatis in 
Germany a few years ago.

[amsat-bb] DOKA-B/ Yubileiny

2012-07-29 Thread andy thomas
Everything I now about Doka-b is at:
 
https://sites.google.com/site/andythomasorg/amateur-satellites/rs-30-yubileiny
 
I have seen it in action, it is a combined hard wired modem interface and az/el 
controller at the ground station end. It is only available to Russian 
(diaspora?) universities and is a protected commercial secret.
 
Each setup is unique to the particular university research project and multiple 
projects at different Russian universities have their own groundstations.  
 
I think you have to consider the satellite part as one half of a whole network 
with the ground station which performs the connection being the other half of 
the circuit. To that extent, consider the satellite as having its own tcp/ip 
address, and its transceiver operating in a psk variant using radio to link 
instead of a cable.  A lot of handshaking etc.
 
I don't think there is a broadcast mode in Doka-b, just the circuit, although 
it is understood to be possible for the transmitter to beacon images and other 
data.

[amsat-bb] ISS Symposium 2012: A personal reflection from G0SFJ

2012-05-05 Thread andy thomas
All,
 
This is my personal reflection on the last few days of the  ISS Symposium 2012, 
organised by ESA and DLR in Berlin. Official highlights are on their own 
website, twitter, youtube etc.
 
It's impossible to single out any particular speaker, so I'd like to give only 
an account of some things that resonated with my own amateur experience.
 
I was very pleased to see in an early presentation by Julie Robinson the images 
of both ends of an ARISS contact, and equally it was heartening to see in the 
NASA Assembly complete edition of the Reference Guide to the ISS on page 95, 
Communications, a diagram in which we see  Ham radio transmits directly to the 
ground. The theme of engagement with young people was a constant throughout 
the Sympsoium with many references to them being inspired by 
astronaut/cosmonaut contacts, and I felt that ARISS was recognised as an 
important programme in this, hence my invitation described on my label , 
amongst the space professionals, as Radio amateur -G0SFJ..
 
Roscosmos/ TsNiiMash also referred to the Shadow experiment which relies on 
sending a beacon or Mayak signal from the ISS and received on Earth by us 
hams - and as a participant I talked with TsNiiMash delegates about that - and 
illustrated their presentations with Chiblis-M and with the MAI SSTV 
experiment. And the 3D journey in an adjoining salon visited the antennae on 
the Columbus module, both in simulation and in a real 3D picture!
 
Over dinner I discussed my personal view that some of us as hams would like to 
see more contacts of opportunity with the crew as time allowed, and I also 
described our work in receiving and passing on cubesat data. There was a view 
expressed that cubesats' reliance on COTS radio equipment did not always teach 
much about radio, and student Cubesat projects did not always lead to the next 
level of bigger and more complex space equipment. I was interested in this 
common problem between space science and ham radio, of getting young people 
involved, in this age of throwaway mobile phones and laptops. I was a little 
surprised that some German delegates I spoke to did not know of the work of the 
ISEI in Leipzig and the Kosmonautenzentrum in Chemnitz, who both stimulate 
young people into space exploration in their own ways, and I think the people 
who do this good work should enjoy a higher recognition.
 
Many presentations demonstrated the utility of space-generated data to Earth 
based problems, and a good example came from the reinterpretation of data taken 
on salt consumption by Sigmund Jähn on an Intercosmos flight in 1978. It was 
both interesting and disturbing to see that bone tissue had not regrown to 
preflight levels in many long duration astronauts and cosmonauts. Visual 
problems were also becoming obvious.
 
The debate extended beyond the current use of the ISS into the future of space 
exploration, Waleed Abdalati giving an inspirational speech about the future. 
Essentially our sphere of action extends only to the asteroid belt. From the 
floor I asked the symposium a question of medical ethics, whether the Mars crew 
should be a younger or an older crew. As I recall, Chiaki Mukai immediately 
picked up on Because of the radiation! and the panel agreed with her and with 
psychologist Peter Suedfeld, who said that life taught many experiences in 
problem solving, that an older crew - by which I think we meant over about 55 - 
would be the ones who should go. Oleg Orlov from IBMP in Moscow concurred. 
Later, when Charles Bolden spoke about the US commitment to a manned flight to 
Mars in 2030, I fell to thinking that the US crew who would go would be 
currently Astronauts aged about 40. That is my personal conclusion. Bolden 
added in his speech - and comes back to
 Earth and has lost his vision. Should we be thinking of that? I think we 
should be thinking of that. There is no doubt in my mind that a manned 
expedition to Mars is not yet possible and Bolden said we also had to look at 
new ways of communications in working up to it. Interesting that in discussions 
over dinner, Amsat-DL's proposed satellite mission to Mars, the dish at Bochum 
and the possible use of a 30 m dish elsewhere was also recognised as a 
potential contributor.
 
It seemed evident to me, too, that the compromises inherent in the design of 
the ISS were beginning to show. Roscosmos emphsised their interest in flying a 
separate vehicle unatennded by humans except at the beginning and end of its 
experiments, in order to take away the minimal disturbances describes by Bolden 
as some astronaut jumping about on a treadmill, but also I think attitude 
changes in pitch, roll and yaw, which are corrected for to an extent in 
experiments, are also a potential problem to zero grvity experiments such as 
crystal growth or metallurgy. And it was evident to me that the data on ozone 
depletion by a JAXA experiment SMILES only touched the edges of the problem 
region due to the ISS

[amsat-bb] CHIBIS-M satellite to launch to ISS

2012-01-09 Thread andy thomas
The CHIBIS-M research satellite is to launch to the ISS/MKC on the Progress 
cargo mission of 25/26 January.

The payload is a scientific satellite to be deployed from the ISS/MKC to study 
the magnetic field in the auroral zone. 


It follows a long tradition of magnetosphere studies dating back to Sputnik-3, 
which (you will recall) nearly beat Van Allen to the detection of the eponymous 
Belts.


There will be a CW telemetry downlink of control/housekeeping data to the 
Kolibri-2000 standard on a frequency around 435 MHz. 

I'll post further info if/when I get it. Meanwhile there's a ton of info in 
Russian at:

[amsat-bb] VO52 and QRP FM

2011-12-03 Thread andy thomas
This is an important debate in difficult times.
 
I am with G7HIA on this one, namely that *** if there is no damage to the 
satellite *** a QRP (below 5w handy) operation might be considered to be 
feasible on a centre frequency. 
 
It is not our bird to give permission. There are of course two transponders on 
board.
 
If permission were given ONLY for QRP in effect this means that WE must police 
this. It would be for us to discorage alligators.
 
(Technically alligators can already use the bird anyway but don't).

at best unpredictable and AO27 is not always on, depends on its ssp. Fact #2 is 
that anyone who is an alligator could have taken over vo-52 and didn't, 
thankfully. Fact #3 is that nobody would without seeking permission.
 
So please cut back from the snide clever-clever remarks about having too small

Hi Andy, G0SFJ

It's impossible to access VO-52 in FM with a 5 watt HT
and arrow antennas because for a decent QSO on CW and SSB
you need at least 50 watt and a 13 dBi 70 cm antenna.

Do not try to access VO-52 in FM with your IC910 

We, operators of VO-52 linear transponder on CW and SSB
in Europe we have a lot of counter measures against any FM
intruder into the VO-52 linear passband.

[amsat-bb] Famous Headline in The Times of England

2011-12-03 Thread andy thomas
The famous headline, in an apocryphal story, was Small Earthquake in Chile: 
Not Many Dead. With due respect to our fellow hams in CE it meant (at that 
unenlightened time) that there had been a sesismic shift that, although 
important to those above it, perhaps did not merit further discussion in the 
Newspaper of Record.

[amsat-bb] Received from shadow experiment

2011-12-01 Thread andy thomas
CURRENT INFORMATION ON 02-05.11.2011 SERIES OF SPASE EXPERIMENT “SHADOW-BEACON”
Dear friends!
It was earlier announced that  timetable of SpEx “Shadow-beacon” sessions on 
November 26-27 -2011 was reduced because the crew is newcomers and need much 
time to assimilate the experience. For the same reason earlier announced 
sessions on December 02-05 -2011 are cancelled all.

Sergey Samburov (RV3DR), the employee of space-rocket corporation Energia 
which is responsible for an amateur radio on ISS, explains that an observed  
fact that the onboard radio “Sputnik” was accidentally switched on standard 
simplex 145.825 MHz not the ordered duplex 144.36/ 145.825 MHz digipeater mode 
because of old age of the onboard gear- it is in use more than 10 years. Some 
times Sergey has already observed  malfunction  like this.

New radio are to be delivered onboard ISS by April cargo vehicle and Mission 
Control Center (TsUP) plans new SpEx “Shadow-beacon” sessions on May-June 2012. 
With this reason you are asked not to delete your registration on our site.

Again  many thanks for those submitted reports and made other assistance! The 
results of data processing will be presented on our site.
We wait for further cooperation!

[amsat-bb] Minimum FCD setup to detect Arissat-1 bpsk?

2011-10-30 Thread andy thomas
This afternoon using a Fubcube Dongle I detected the arissat-1 spectrum on 
145.920 as the transmision doppled across. I've screendumped it as evidence! 
The signal was weak but visible (and audible) and rapid as you would expect at 
the nominal frequency. I used FCHiD to set the frequency and HDSDR to demod it 
at usb. 
 
I owe it all to my homebrew one-transistor untuned preamp (RSGB's VHF-UHF 
handbook) at the end of a 6 ele XY fixed in az/el.
 
It didn't decode at the tlm software though, and I'll try again next weekend 
using DK3WN's doppler control software. 
 
However I am pleased I have detected arissat1 bpsk with a FCD - that's 
one small step...

[amsat-bb] Re: Oscarlocator

2011-10-14 Thread andy thomas
At the flea market in St Petersburg (Russia, not Fla!) this August I bought a 
Russian ex-ship Oscarlocator- type device for geostationary satellites in the 
Inmarsat series.
 
It's a map of the world with the satellites marked on it along the equator, and 
a transparent plastic overlay from which you can read the az and el to the 
satellite from your position. It rotaes around a central screw.
 
Obviously it'll work with any geostationary satellite once you have drawn it in.
 
I have scanned all 3 components - map, overlay and Russian text - and 
translated the text. I sent it to amsat-uk for their bulletin but I don't think 
they are interested. Maybe nobody is. But if anyone is, let me know and I'll 
post it on my website.

[amsat-bb] Arissat-1 silent over UK: Explanation

2011-09-26 Thread andy thomas
As reported over the weekend, Arissat-1 is no longer audible in the UK, because 
she does not switch on until after about 14 minutes from entering sunlight. 
 
I believe the sequence is:
 
enter sunlight: MET starts: timer activated
14 minute wait before tx - other systems live
Tx on with data at a MET of 14 minutes
Tx sequence
 
We in the UK now have to wait unril the orbit continues to precess to the late 
evening (about 10 days' time)

Did not catch the second voice digit! MET is One shh  But satellite is 
switched on.
 
On 18 september the voice announced MET (19 and 21) equalled the time in 
sunlight, as I have calculated back using today's keps, within 1 minute. 
Allowing for keps 1 week old I think the MET is in fact announcing the time the 
satellite wakes up as she enters sunlight, but there are no fm transmissions 
at that time. The latency is up to 10 -19 minutes (if I had the second digit I 
could be more precise,hi!!)

I am just waiting for what the MET is announced (voice tlm) as at 1032 utc AOS

Interesting
 
My observations last weekend show that MET matches the satellite entering

18 September
 
calculated Time into sun: 1004 utc
Time of obs (announcement): 1023 utc
Voice announced MET: 19

maybe the voice tlm MET isn't accurate either!
 
howver I calculated the time of the entering sunlight using the keps of 24/9, 
not the keps of 18/9, via satpc32.

Based on posted observations, I have come to the conclusion that the 
satellite's MET comes up at either 0 or 1 when the satellite turns on, after 
the 10-or-so minute delay after entering sunlight.  Depending on what mode it 
thinks it should be in, I suppose it's possible that it might in fact be in one 
of those power saving quiet periods at that time, and only be heard a few 
minutes later.  Entering sunlight is not a knife-edged event in orbit; there's 
a short ramp in power, so (playing arm-chair engineer here) I expect it would 
be in low or emergency power mode for a short while.

 Did not catch the second voice digit! MET is One shh  But satellite is 
 switched on.
  
 On 18 september the voice announced MET (19 and 21) equalled the time in 
 sunlight, as I have calculated back using today's keps, within 1 minute. 
 Allowing for keps 1 week old I think the MET is in fact announcing the time 
 the satellite wakes up as she enters sunlight, but there are no fm 
 transmissions at that time. The latency is up to 10 -19 minutes (if I had the 
 second digit I could be more precise,hi!!)

 I agree with this observation here at IO92NL. 
 
 Arissat-1 does not switch on immediately when in sunlight, I have missed 
 several passes this morning and in the last few days. 
 
 I am just waiting for what the MET is announced (voice tlm) as at 1032 utc 
 AOS (coming up) and will backtrack to how long she has been in sunlight. The 
 difference ought to tell us the latency.

[amsat-bb] Arissat-1 Voice telemetry analysis from G0SFJ

2011-09-21 Thread andy thomas
I have submitted for a tlm certificate my analysis of the voice telemetry from 
Arissat-1 on certain orbits in September (when I was present, hi).  
The dates of the receptions in September are in the analysis spreadsheet.

The MET is decreasing, I think this is because the satellite comes out of 
eclipse and swithches on nearer the observation, as the orbit is precessing

I think the analysis shows that as the MET decreases, the IHU temperature 
decreases, and the battery current increases (this is a lesser negative number).

Put that another way, as the MET in sunlight increases, the IHU temperature 
increases and the circuit current decreases (greater negative number).

However I don't know why the circuit reports a negative current, or even if the 
voice tlm is accurate. I'd be grateful for any comments.

While we are about it, although I don't wish to add to the names - RS01S,

[amsat-bb] Simple preamp improvement

2011-08-06 Thread andy thomas
I found that a homebrew single transistor untuned preamp (page 4.42 of the 
RSGB's VHF/UHF handbook) was sufficient to lift pictures out of the noise - 
thought the funcube developers might reflect on this , looks like it's an 
essential feature for the ground station.

[amsat-bb] Russia Today reports Kedr deployment

2011-08-04 Thread andy thomas
Guys

you won't like it - brace yourself:

BEGINS
New satellite to commemorate first space flight
permalink email story to a friend print version Published: 03 August, 2011, 
20:02 


Two Russian cosmonauts have left the International Space Station for a six-hour 
spacewalk to mark the 50th anniversary of the first-ever manned space flight by 
Yuri Gagarin with the launch of the unique microsatellite.
­The cosmonauts will spend about six hours outside the ISS and for the first 
time ever computerized Orlan-MK spacesuits with liquid crystal displays will 
give advice and instructions in case of emergency situations, such as increased 
oxygen consumption.
During the spacewalk, the cosmonauts will launch a microsatellite made entirely 
by Russian university students.
The satellite – which is dubbed “Kedr” (cedar) after Yuri Gagarin’s call sign – 
will be broadcasting greeting messages from outer space in 50 different 
languages to mark the 50th anniversary of the first-ever manned space flight.
The cosmonauts will also install laser communication equipment on the outside 
of the Russian segment of the ISS. However, it does not mean high-speed 
internet will be available in the Russian segment, as long as “the new optical 
equipment is intended primarily to transfer science video to enhance the 
efficiency of the scientific activity of the cosmonauts,” the head of the 
extravehicular activity department of RSC Energia, Aleksandr Polishchuk said.
With the US Shuttle program shutting down last month, Russia is currently the 
only nation able to send people to the stars.

[amsat-bb] ONE ARISSAT ANTENNA MISSING, Reports Novosti

International Space Station
Two Russian cosmonauts, Alexander Samokutyayev and Sergei Volkov, completed 
their 6-hour spacewalk on Thursday with a 40-minute delay and returned to the 
Russian segment of the International Space Station (ISS).

They carried out a manual launch of a mini-satellite and installed new stream 
video equipment on the station's outer surface.

This was the first spacewalk for Samokutyayev and the third for his colleague 
Volkov.

The launch of the Kedr mini-satellite, designed to transmit greeting messages 
in 17 languages, Earth photos and telemetry data from its service systems, was 
delayed after the cosmonauts discovered that one of its two antennas was 
missing, but they nevertheless launched the satellite with only one antenna.

The cosmonauts also installed three containers with microorganisms and mushroom 
spores on the Pirs docking compartment to study their influence on materials 
used in spacecraft construction.

At the end of their spacewalk, the Russians took pictures holding photos of the 
first cosmonaut Yury Gagarin, spacecraft designer Sergei Korolyov and Soviet 
astronautic theory pioneer Konstantin Tsiolkovsky with Earth in the background.

[amsat-bb] Kenwood THD-72A/E Duplex function

2010-10-03 Thread andy thomas
At the (British) National Hamfest yesterday I had a play with the 
pre-production model of the THD-72E and asked about full duplex.

I couldn't get into full duplex on the menu and had to give the set back but I 
insisted onthe question in the name of AMSAT and they went to the manuals while 
some other guys played with it.

On the second manual(printed off the cdrom) - which they said was about the 
packet function - there was the following instruction:

FULL DUPLEX
Ths transceiver is also capable of simultaneously transmitting and receiving 
signals. So it is possible to transmit audio on the current band while 
receiving packet data on the other band (data band).

1 Set operation band to band B
2.Press [F DUP] to enter Duplex mode
...

Notes
* When operating on band A you cannot change to full duplex mode.
* When in single band mode and Band A/B is set to VHF/VHF or UHF/UHF you cannot 
change to Full Duplex mode.
* When usin the Full Duplex function, connect an earphone to the SP jack. using 
an earphone will prevent feedback that can cause the transceiver to emit a 
howling sound.

I have photographed these instructions and transcribed from the photo. For some 
reason I photographed the manual not the radio which is a squat fat two-tone 
grey thing. It's got a gps built in. Available end 2010, they said.

But Russia, Ukraine and Belarus require a customs declaration about high

Within the EU I take the handheld with me in carry-on luggage with a full

to show it to the pilot (or anyone else!!). I separate the battery from the HT 
for the xray and offer to connect and switch on if asked.

I carry a full licence with me and I have a photocopy licence in my checked-in

[amsat-bb] Graph of eclipse/sunlight

2010-01-23 Thread andy thomas
I've been looking at some cosmonauts' historic accounts of missions on the 
Salyut series of orbital spacecraft. Characteristically they have drawn a graph 
of the eclipse and sunlight times of the long duration mission. The vertical 
axis is time after EQX of the first orbit of the day (the entry into and 
departure from eclipse is marked on this axis in 5 minute intervals) and the 
horizontal axis is the mission day. 

The result is a graph in which lines extend horizontally conencting the eclipse 
times (both in and out), and they have characteristically filled in the 
darkness time with dark pen. On one print the light time has another contour 
with what appears to be sun angle.

The graph has then been added to by showing the plan and actual activity on 
that mission day.

I would find it interesting to compute a similar graph for a long duration 
mission of the ISS. But I have some difficulty. From a TLE I can do the 
following:

*calculate first eqx in utc

but can't find the time of crossing into eclipse without knowing the position 
of the sun and the position of the spacecraft in relation to the sun 
(Subsatellite point?).

Does anyone have any idea about the calculation and data involved? It must have 
been a hand calculation carried out by cosmonauts, but once a simple program is 
written I could use excel to draw the graph. Maybe a standard predictor program 
can produce a data output that could be rewritten into excel? I'd need the 
eclipse times on the orbit following the first eqx of the day.

I would appreciate any input, also any thoughts of why they would want to draw 
it (have only thought of observation and power).

many thanks

YOAGAN-7 was launched from Jiuquan by a Chang Zheng-2D into a sun-synchronous 
orbit about 400 miles high yesterday. Is this the same mission for the ham 
satellite? Jiuquan launches to polar orbit from 41 degrees North.

[amsat-bb] Re: chinese satellite

2009-12-10 Thread andy thomas
I know Yaogan-7 is supposed be an earth observation satellite but there is more 
than one way to skin a cat - remember the RS- series of satellites piggybacking 
on a common power supply bus - and the fact that the HF commemmorative station 
is suddenly activated may well mean something. If you go to celestrak and look 
at the last 30 days' launches you will see that there are a number of items 
identified as rocket debris with a 97 degree inclination obviosuly part of the 
launch sequence for Yaogan-7's 98 degree inclination. So she might well be up 
there.

[amsat-bb] New ariss antenna: question

2009-11-21 Thread andy thomas
fascinating watching the installation of the dual band antenna. many thanks to 
all concereed.

it prompts me to ask:

1. what wasthe location of the antenna were they using before?

2. I thought I heard that the new ARISS antenna is on the starboard side - I 
assume that is relative to the direction of travel - whereas the AIS antenna is 
on the earth facing side. What will be the effect of the location of the ARISS 
antenna on those of us at latitudes with values above the ISS orbital 
inclination (of 51.7)? ie bearing in mind the attitude and direction of the 
station when at these high latitudes, will the architecture of the ISS shadow 
the antenna? Or are there so many reflections it doesn't matter?

[amsat-bb] Re: using a microsat as a potential high altitudeVHF reflector

2009-10-29 Thread andy thomas
I still think that a large unfolded and/or (partially?) inflatable structure of 
reflective material structured as resonant reflectors could be an interesting 
passive reflector of ham frequencies if it was placed on the Moon. It would be 
easier than a powered active repeater.

I know about moonbounce obviously and the laser system left behind by Apollo.

[amsat-bb] New APRS satellite programme

2009-10-04 Thread andy thomas
I saw this software at the UK national hamfest this weekend:

http://www.crosscountrywireless.net/aprs_messenger.htm

I'm sure it will have an application - see SAT (no Ack frames) mode/

Also a piece of easy compatible APRS hardware.

i have no connection to the company but it seems to me to be an interesting bit 
of kit.

[amsat-bb] Mystery bird, RS30 Yubilieiny system and beacon decode

2009-09-19 Thread andy thomas
For a summary of information on RS-30 Yubileiny please see my pages at:

http://sites.google.com/site/andythomasorg/amateur-satellites/rs-30-yubileiny

or follow the links to this page from 

http://www.andythomas.eu

This refers to original material from Kaluga anticpating a beacon frequency of 
435.353 which was not used last year. Obviously it's switchable.

I have not checked the keps for RS30 for some time but I remember they were 
hard to find. Are we sure the mystery bird isn't RS-30?

[amsat-bb] Re: Universitetsky 2 (Tatiana 2

2009-09-18 Thread andy thomas
When I was at MGU (Moscow state university) in May this year I heard that 
because of the controversy over the use in the Amateur band of the multiplex 
system Doka on Yubileiny, they had decided not to use an amateur band on this 
bird. Doka is a system used by Russian universities, originating from engineers 
in Kaluga. Instead they would use the scientific/educational band at 1.7 GHz, 
near the HRPT band, and installed a small dish on the roof of the high-energy 
physics building for that purpose (I have stood next to it). The location 
cannot see low elevations because of nearby high buildings. Therefore I don't 
think Tatiana 2 has a 435 MHz beacon but i am checking with friends in Moscow.

I know this is an old chestnut, but when in satpc32 and with both frequencies 
set on the iss simplex 145.825, satpc32 shows the up/downlink doppler but 
switches the 70cm tx subband. How do I configure so that the up and down links 
can be in the same band?

immediate problem is packet on the iss (in between pollux!)

I found out it couldn't be done in HRD so i am evaluating satpc32.
