I assumed ANUSAT to be an 'amateur satellite.

Perhaps I presumed too much.

[amsat-bb] Anusat - the reply.

[John Hackett]

Trevor,
  To answer your question ...

 I followed the third link from the Southgate Amateur Radio Club bulletin
regarding ANUSAT and the quote to which you refer..

The complete text follows ... 

(According to the story, the quote is by the Vice Chancellor of the Anne 
University ... which is why I found it worthy of note).

ANUSAT being an acronym for ANne University Satellite

While not SPECIFICALLY stating exam results would be tramsmitted by 
this satellite Dr P. M. Jawahar's remarks are quoted in the same ontext 
and paragraph as the the rest of the information regarding the Anusat 
satellite, which, according the Amsat India website is an 'AMATEUR' satellite.

12 years ago we were warned by Vommander John Brannegan that we would lose
the amateur satellite bands to the universities.

It looks like Winston Churchill was on the ball as well ... this is not the 
end, it's not even the beginning of the end - but perhaps it's the end of the 
beginning. 

(With apologies to Winnie The Poo).

India Launches University-built Satellite



 By P. Vijian



NEW DELHI, April 20 (Bernama) -- India successfully placed two
satellites in the sky early today, one of which was designed and built
by Anna University in Chennai -- the first satellite built by an Indian
university.


 The Polar Satellite Launch Vehicle (PSLV-C-12) soared into the sky
at 6.45am (9.15am in Malaysia) from the Sriharikota spaceport in Andra
Pradesh, in south India, lifting the two satellites, RISAT-2 and ANUSAT
-- an abbreviation for Anna University Satellite.


 "The indigenous ANUSAT was designed, built and fabricated by 10
faculty members from Anna University. It took us nearly eight years to
complete.


 "This micro satellite will help in storing and forwarding data. It
will help us send confidential data, like examination papers. This is a
proud moment for India and the university," Anna University
vice-chancellor Dr P. Mannar Jawahar told Bernama.


 The India Space Research Organisation (ISRO) funded the ANUSAT
communication satellite, weighing 40kg and costing nearly RM5 million.
It has a life span of two years.


 The Israel-designed RISAT-2 or Radar Imaging Satellite, weighing
300kg, with all-weather capability to take images of the earth, would
enhance ISRO's disaster management ability.


 "RISAT will help us in monitoring natural disasters like floods
and cyclones. It has a life span of three years. ANUSAT is the first
experimental communication satellite built by an Indian university
under the guidance of ISRO," ISRO spokesperson S. Sathis told Bernama.



 Last October, ISRO launched the Chandrayaan-1 spacecraft that is now exploring 
the moon from lunar orbit.

I am not aware that anyone at the University has said that confidential data 
would be passed by the satellite on an Amateur frequency. Do you have any 
University references for that quote? 



My understanding was that this was a technology demonstrator for a store and 
forward system. 



While you could in theory build a dedicated satellite for handling exam papers 
you have to ask why bother since you could use any number of far cheaper 
alternative systems. 



It sounds to me like the type of paper justication you might make to get funds 
for a demonstrator project. Bear in mind that the mass media can distort things 
that they don't understand. 



One of the students, Sidharth Balasubramanian, who was involved in the 
development of the ANUSAT communications system has some information on his 
website. No specific freqs quoted except for the 149.522 MHz command receiver,

[amsat-bb] Tracking on your cellphone.

[john hackett]

To the Gentleman wondering about tracking on a cellphone.

Try this ...



I've been using it 'portable' for two years now and it's an excellent little 
program which 'agrees'
totally with both NOVA and InstantTRACK - (providing you update the keps every
fortnight or so).

Several references to it can also be found on the OBSERVATIONS page at ...

 

(Observations from Norway).

I hope that helps.

I have my cellphone attached to the handle of the Arrow aerial with a standard 
car dashboard
cellphone holder so that when I wave my 'pointy stick' at the sky I can 'see' 
where to point.

What if the locals *DO* think I'm bonkers? ... who cares !!.

[amsat-bb] An alternative ... or ... competition !!!.

[John Hackett]

Ladies and Gentlemen,
   For those that don't know it, The chief of 
RosKosmos, the Russian Space Agency *confirmed* last week the Russian intention 
to pull the plug on the ISS in the 2015 - 2020 timeframe and to construct 
another dedicated Russian 
space station.

According to Anatoly Zak RosKosmos informed NASA of these plans 14 days ago.

The new Russian station is *NOT* intended to be a laboratory like the ISS but 
more of an in-orbit contruction platform for future Mars-like and outer space 
missions.

The station will comprise a maintainable 'ball' section with several docking 
ports 
with attachable modules.

I propose that amateur radio satellite operators get together and form a group 
to suggest/try to influence/impliment an ARISS type of project for this space 
station.

A Strela type frame could be attached to the underside of the 'ball' and since 
the station is planned for a Molinya type orbit the coverage would be suitable 
for DX.

The planned orbit would put the station predominently over Russia - as opposed 
to the current ISS equatorial orbit.

Personally, I would suggest an RS-10/11 RS-12/13 clone with a ROBOT ...
(read: propagation tester) - as these satellites were without the shadow of a 
doubt the best for recruiting newcomers.

It would, in my opinion, be a viable concept and an alternative to some of the 
latest 'ideas' of a transponder on the moon ... which wouldn't 'catch' many 
potential newcomers but would (*IN MY OPINION*) only serve a few dedicated 
'experts' ... leading to the demise of amateur satellite communications in 
general.

Comments, monies and praise to LA2QAA.

Criticisms, horsewhipping and flaming to GM1SXX.

73 John.   

Interested parties may read the following ...



The OPSEK project

  By
2008, the Russian successor to the International Space Station, ISS,
was identified as Orbitalniy Pilotiruemyi Eksperimentalniy Kompleks,
OPSEK, or Orbital Manned Assembly and Experiment Complex in English.*
Unlike previous designs of Mir, Mir-2 and the ISS,
the heart of the station would be a four-ton ball-shaped node module.
Equipped with six docking ports, this relatively small and simple
element would be the only permanent element of the station. All other
modules would come and go as their lifespan and mission requires.

  The initial architecture of the OPSEK complex could be built out of 
modules originally planned for the Russian segment
of the ISS. The exact scenario of the OPSEK assembly would depend on
the end of the ISS and the readiness of the latest Russian modules.
According to a 2008 scenario, the MLM multipurpose module, the node module and 
a pair of NEM power platforms could be first launched to the ISS in 2011, 2013 
and 2014-2015,
respectively. With the deorbiting of the ISS looming around 2020, these
modules could separate from the old outpost to form the core of the new
Russian station. Another, more controversial scenario considered the
separation of the practically entire Russian segment, including the MIM-2 
docking compartment and the Zvezda service module,
prior to the ISS deorbiting. In this case, the 20-year-old service
module would temporarily take a responsibility for the flight control
of the OPSEK, until its replacement with a 40-ton versatile core
module, UMB, launched by a next-generation rocket from yet-to-be built launch 
site in Vostochny during 2020s.

  The
separation of the Russian segment from the ISS would leave the rest of
the outpost without effective orbital maneuvering capabilities, leaving
the European ATV spacecraft
as a likely candidate to perform the tasks of attitude control and
deorbiting. To achieve this the ATV would have to be modified to enable
its docking with the US segment of the ISS.

  Depending
on the operational orbit selected for the OPSEK, it might be necessary
to change the orbital inclination of the modules departing the ISS and
forming the new station. The lowest inclination accessible from
Vostochny is 51.7 degrees, while the ISS is orbiting the Earth with the
inclination 51.6 degrees toward the Equator. It is estimated that one
or two Progress cargo ships would be necessary to push the modules from one 
inclination to another.

  From
official statements during 2008 and 2009, it is clear that the one of
the chief objectives of the OPSEK complex would be the support for
expedition to Mars. All major elements of the Martian expeditionary
complex, such as main habitation module, Mars lander and
nuclear-powered space tug would dock to the station before its
departure from the low-Earth orbit toward Mars. The Martian expedition
would at the OPSEK as well.

  The station would also play a similar role in lunar exploration. Reusable 
space tugs could link OPSEK with the Lunar Orbital Station, LOS, in orbit 
around the Moon, thus creating a trans

[amsat-bb] Molinya

[John Hackett]

David,
 My use of the word Molniya was ambiguous.

I should !!! have emphisised *LEO* elliptical. Let me explain ...

The word Molinya in Russian means (literally) 'lightning' but in a space 
context it is accepted to mean ELLIPTICAL ... as per their TV satellite 
orbits which are in English dialogue would be classified as *HIGHLY* elliptical.

The planned space station is envisaged in a 70 degree LEO orbit.

I apologise for my misleading remarks.

Hi John.
 
Just wondering  Is a Molinya orbit highly elliptical  
??   If so, then it cant really go above 1000km high or the crew will 
get zapped by the protons in the lower van Allen belt.
 
Thanks

Joint Observations
07 July 2009
GM1SXX & LA2QAA

The problem 
with Space Stations... and a possible Opportunity.

When the 
International Space Station is scrapped probably in the 2015-2018 time 
frame, a valuable space asset will be lost.  It needn't have been that way, 
and the Russians have wakened up to a new possibility, one that was sadly 
missed 
on the ISS.

ISS is built 
around MIR-2 hardware. The core, the Zvezda module,  is essentially 
unchanged from the old MIR design,  a tubular cylindrical living area with 
solar 
arrays attached to a docking 'ball' with five docking ports available.   
Once Zveda becomes  life-expired, the whole assembly is useless.  A 
more practical approach would have been to fly a 'passive' six-port docking 
ball, to which active modules can be docked. In this way, station elements 
could 
be detached and discarded as they reached the end of their design lives while 
the docking ball remains a 'permanent fixture' in space.

Enter 'Orbitalniy 
Pilotiruemyi Eksperimentalniy Kompleks', OPSEK, or the 'Orbital Manned 
Assembly and Experiment Complex'   This is a plan for a future space 
station unveiled by the Russians in 2007, and documented by Anatoly Zak on his 
web-pages.  It centres around the use of a passive 4 ton 'docking ball' 
with six ports, to which additional modules can be attached.   


Such a docking 
ball  in LEO would have the primary purpose of 'tying a space station 
together', by providing passive docking ports, but it could equally well serve 
as a 
long-lived platform for a 'parasite radio package' in the same way that the old 
RS10/11 and RS12/13  'satellites' worked. For those not old enough to know, 
these were 'parasite' transponder packages attached to spacecraft that were 
powered from the main craft.  So long as the packages antenna(s) could be 
mounted on the ball's -Z axis, it could serve as a useful radio relay 
(transponder) in LEO.  Such a package would have a fairly small physical 
footprint and would require very little driving power from the 'mother-ship' or 
solar panels (if fitted). It would obviously be desirable to derive power from 
the mother-ship in the interests of simplicity and longevity.

With launches 
becoming increasingly difficult to find on cost grounds, this would be one 
possible way to provide a future new transponder in LEO.  If the package 
was small and light enough, it could possibly be carried to the (new) space 
station by a progress cargo vehicle as freight, and attached to the docking 
ball 
structure during a space walk.  What is more, it could function for a long 
time, limited only by the overall life of the space complex.

Several people in 
the UK already have a track record in building space-rated hardware in addition 
to another amateur in Holland, who has built space qualified hardware including 
the backup transponder for HM-1 AKA VUSAT, as well as a new linear 
'Pico-Transponder'. They know who they are... you don't need to know, at least 
not right now :-)  The expertise already exists to supply space rated 
hardware to fly on such a mission. and we do feel that the possibility of 
flying 
such a mission should not be passed over.  I'm sure there are people in 
Russia (from the old RS satellite team) who would be just as keen to see this 
idea fly.

[amsat-bb] The future of the ISS.

[John Hackett]

Group,
  Once again, it seems that some of the Amsat-bb members have 
apparently no clue as to what goes on outside America.

The future of the ISS, discussion ...

It does appear that some of the contributors are oblivious to the fact that 
The Russians have already informed NASA that they (The Russians) intend 
to pull the plug, to concentrate on their own space station ... more than 
likely backed by The European Space Agency.

News and comments at the end of the following website. ...

 

GM1SXX and myself wrote an article on this very subject some time ago. 

Those interested may read it at ...



Somebody commented - "It's politics" ... that part is true, it's mainly a 
combination 
of politics and money.

My own personal opinion is that the Russians don't fancy the idea of footing 
the bill alone, and prefer to do things their own way.

[amsat-bb] Staus? ... come back next week!.

[John Hackett]

Err ... chaps,
  This evening, Sunday the 30th of August, 21:10 GMT. 

The Amsat-NA satellite status page reports FO-29 as being A-OK.

It's the 6th day of silence now - (the D.Carr page status is correct).

*NOT* very Impressive Amsat. 1 day, OK, 2 days (marginally) acceptable, 
but 6 days? ... doesn't exactly incite to impress the pitential newcomer.

Yes, I *KNOW* they're volunteers. I understand the workload. The potential 
newcomer doesn't - and he may wonder why he can't hear his downlink.

The newcomer probably doesn't subscribe to the ANS yet, and maybe has 
never even heard! of D.Carr & Bob Bruninga.

[amsat-bb] Facts.

[John Hackett]

To anyone who may care.

I made Joe public - (as one gentleman referred to himself) - aware of 
some INCORRECT information on the Amsat-NA satellite status page.

I *DID NOT* critisise any particular individual - (though one member of the 
b.o.d. took it upon himself to accuse me of embarrassing HIM and that *ALL* 
my communications were criticising Americans and Amsat.

That is simply not true. 

I pointed out some INCORRECT information.

Those are are the FACTS ... nothing other was implied.

If that gets me excommunicated - then so be it - it may well be time to 
leave the organisation to the new blood.

There is a VAST difference in 'constructive criticism' (for the good of all),
even if it is satirical and intentionally tongue-in-cheek ... and the 
intentional
tearing down of someone elses efforts - (which I have NEVER done) - at least 
certainly not intentionally ... (and I would like the benefit of the doubt).

Best wishes to those older friends who used to enjoy my contributions.

I also note that Mr Glasbrenner referred he whom enquired about AO-7's status, 
to the D.Carr page.
Wasn't that rather inopportune after making such a fuss about the Amsat page

Americans - (operating proceedure) and the Amsat organisation (full of clever,

I'd hardly call Bill Tynan's plaque to LA2QAA as proof of concept of my 
criticising Americans or the Amsat organisation - however, if a current member 
of the b.o.d. gets his rocks off by a tantrum ... good luck! to him, I've faced 
slightly more wrath than that.

Personally, like I mentioned in

my personal opinion rather lax - volunteer or not.

That Mr Glasbrenner was a good deal rattier direct, was probably due to him 
confusing satire with 
criticism on a previous occasion ... and no, eventual satire has *NEVER* been 
directed at an individual.

That, as they say - is it. I felt I needed to justify myself for anyone 'just 
wondering' where all that temper
came from.

I apologise for the bandwidth if you think it's misused.

In my opinion, no permanent harm done. Worse things happen at sea!.

[amsat-bb] Err ... right.

[John Hackett]

Yes, Dan,
 I did get that bit. 

The other half of the "twisted pair" is GM1SXX, IT engineer by trade and 
software guru.

If my proposal does bear fruit, would you be interested in giving D-Rats a 
haircut?.
(read: produce a dedicdated cut-down 'space' version).

As per today, we're still in the concept thrashing department. 

The first dedicated D-Star satellite launch is slated for October 2010.

Another 'notable' is Alexander Zaitzev, director of IZMIRAN Russia. - 
(Ionospheric 
sounding studies for the University of Moscow) - by small satellites.

Information about IZMIRAN can also be found on the Observation website.

[amsat-bb] Distance records for LEO's.

[john hackett]

Kevin,
 My personal best on an LEO is Norway to Japan - (FO-20 in 1997).

Depending whether you classsify AO-7 as a LEO bird - (with an orbital height of 
1400Km) - the current record there 
is 7500 - 7700Km, by several stations.

You may have been only interested in FM satellites, to9 which I have no idea.

Hope that helps somewhat.

[amsat-bb] Hoa Camsat !!!!.

[John Hackett]

In the event that anyone at Camsat sees this mail ...

It would have been nice with a SITREP - (situation report) - about the weekly 
schedule for HO-68. 

here are a *LOT* of people 'wondering' ...

I summise it has something to do with the President of China visiting the 
ground station and 
Alan Kung being in the entourage ... but still, a SITREP would have been nice.

On behalf of the myriad of satellite operators in Europe I would apprecate some 
word on
the current status of HO-68 ... at your convenience.

Thank you.

[amsat-bb] IOTA ... (Islands On The Air).

[John Hackett]

INFORMATION FOR IOTA HUNTERS.

Normally, in a satellite exchange, I only give my locator (JP33WB) - but my QTH 
is in fact
FREI ISLAND, IOTA EU 36, located at 63.02 degrees North and 7.48 degrees East.

It's just too long winded giving the entire QTH designation on CW so for the 
IOTA hunters,
please be aware that JP33WB is IOTA EU-36.

I've lived on Frei Island for the past 21 years. Previous to that, my QTH was 
Gossen Island,
IOTA 56. 

I've been involved with the IOTA program since it was started in the early 80's.

I've worked the analogue satellites daily from and including RS-10 up to and 
including HO-68
- except for 1 year AWOL (hospital) in 1997 - 1998.

The 'station' is still operated daily ... but in a much smaller capacity. 
Milliwatting now instead 
of QRP, skill over *BRUTE* force of 2 watts.

100mW ito an 'Arrow' is more than enough on HO-68.

It still cracks me up thinking about K4***'s ... "You need at least 100w and a 
good antenna
to work AO-7" ... you probably do - if you use a 50 ohm resistor as an aerial.

Incidentally, just the other day I was chatting to a station who mentioned he 
was G-QRP 
13,000 and something-or-other ...

It made me realise how time flies, I was G-QRP nr 74.

[amsat-bb] MORE POWER !!! EGON ...

[John Hackett]

To whom it may concern,
   A lot of the experienced satellite 
operarors will recall Jan King 
VK3GEY / W3GEY as the project manager for AO-7, consequently, here probably 
isn't a better 
authority on the grand old Lady. 

A few years ago GM1SXX and myself were in contact with Jan after I'd discovered 
and catalogued the operation of the mode timer - and noted the fact that it 
wasn't as described in the 1974 Amsat newsletter. 

After it's resurrection and for several years thereafter I took an active 
interest in this veritable old girl
 but eventually moved over to HO-68.

Due to moving into an old people's facility where aerials are not allowed I had 
no choice other than to 
'bin' the satellite array and disguise a chopped down version as a TV (!) 
aerial on a small rotor.

Unfortunately, I was limited to 200mW so as not to interfere with the digital 
TV decoders installed in the rooms. 

200mW was adequate on HO-68. however, due to the FM mentality promoted by 
Amsat, the uplink power
on the other satellites has been increasing ... particularly by the newcomers - 
who apparently, and mistakenly, think that high power is necessary. It's *NOT* 
... nor is an EME class aerial array necessary to work LEO satellites. Ditto 
circular polarisation.

FACT: polarisation is *ONLY* circular along the boresight of an aerial.

High power is detremental to space bourne transponders - think power budget - 
causing among other 
things, FM'ing. 

For the 'details', please read up on the subject. A positive mine of 
information can be found on the AO-7 
Resource Page - (which I stopped administering several years ago) - or ask an 
experienced operator to explain why! high power is detremental - (power sharing 
on a linear transponder or 'hogging' it on FM).

As mentioned, Jan King is probably the foremost authority on AO-7. I'd like to 
quote a couple of his  comments ...

  * Jan King, W3GEY notes that AO-7 had (has?) a very sensitive receiver and a 
good uplink antenna.
 5 watts EIRP should provide a good downlink. Amplifiers are not required for 
the uplink. 
   
 * Excessive uplink power may be cause FMing of the transponder and may be 
causing the input voltage to the regulator that provides 6D to fluctuate 
causing all telemetry to be bad.

Jan also explains - (on the AO-7 resource Page) - how to determine when the 
telemetry is valid - 
(and when it''s not).

Serious operators take the trouble to read the recommended operating 
proceedures.

Finally, a reminder ... (repeated annually).

The Resource Page log  was always meant as an ACTIVITY log - not! a 
competition. Mistakes that are 
not rectified make the statistics, over time, invalid.

One can correct one's own mistakes by clicking on the spyglass to the left of 
the log entry ... and follow 
the onscreen instructions.

The editing facility has*ALWAYS* been there - (but many people don't use it).

Please do *NOT* make several entries for the same pass unless you work more 
than eight (8) stations 
on a particular pass.

[amsat-bb] HO-68 comments.

[John Hackett]

Once again, I note the whinging about HO-68's orbit not being suitable for a 
particular station ... or two.

I'd like to remind the gentlemen concerned that HO-68's on time is NOT designed 
to favour one particular area. Please remember, it's a Chinese satellite and we 
should abide by and respect their decision of when to activate the transponder.

For my own use,the HO-68 late afternoon GMT 'on' times are optimum. 

Conversly, I 'could' complain about the ISS orbit - (but I don't) -only 'seeing 
it at max 6 degrees for 90 seconds every 2 days - (read: unworkable from my 
QTH), dirro SO-50, AO-27 and VO-52.

What may be poor for one operator could be optimum for another.

Please remember, the world consists of more than The United States Of America 
and Southern Europe.

[amsat-bb] An explanation of the word whinging - from an Englishman's perspective.

[john hackett]

Sir,
  Herewith, an explanation of the term whinging ...

Some dictionaries give the definition of whinging as complaining while others 
derine it as complaining 
in a continual whining manner ... the keyword being 'continual'.

The colloquial 'Manchester' definition of whinging is a repetitive comment - as 
has been noted several times on various reflectors --- (ergo - 'continual').

One particular station stated he resented being referred to as a whinger ...

No offence was intended on my part but if offence was inadvertantly taken, I 
sincerely apologise.

73 John.   

NB.

Despite the LA callsign, I am! a Limey from Manchester so perhaps I should have 
chosen my words 
a little more carefully, again ... no offence was intended.

[amsat-bb] HO-68 orbit comments.

[John Hackett]

Hello Dom,
You are of course right.

I have been in contact with Alan Kung regarding various aspects of HO-68 but as 
you correctly state, 
The Chinese don't seen to want to share the workload.

I went as far as offering donations to help Amsat China  but was politely 
refused (!) ... the implication being that subscriptions would require 
reciprocating with 'information' - (which was NOT my intention).

I think your comments will give people a better understanding of why the orbits 
are not always otimum
for certain times/areas.

73 John.   

CC'd to the group and the Amsat-bb for general information purposes.

Friends,
Unbeknown to me, my computer was compromised with a Trojan.

I have now run a complete scan for viruses and Trojans. The computer is now 
clean.

I apologise for any inconvenience caused - even though it really isn't my 
fault. 

I have *Always* had a recommended antivirus program installed. I now have 
Spybot installed permantently as well. It *DID* show and delete the problem.

Again, my apologies for any inconvenience.

73 John.

Yes Bill,
 Like I said ... the *TRANSPONDER* will be off ...

See <http://oscar.dcarr.org/>

The *BEACON* will be on - for testing.

73 John.
