Rupert, I think that is a fair assumption on your part, but only because the are no new ideas being presented that have commercial potential that can use Amateur Radio as an inexpensive to proof of concept. In the present Amateur Radio community only Emergency Communications is getting the publicity. Perhaps FEMA or the Red Cross might help pay for an emergency communication satellite otherwise it is LEO's forever!

The problem is that amateur radio doesn't significantly reduce the cost of a satellite. Any interest by the Red Cross would not be in the satellite but in human volunteers that might come with it. Unfortunately, the LEO satellites that hams can afford generate little interest in this forum. 73, John KD6OZH - Original Message - From: "Art McBride" To: "'rupert red'" ; Sent: Sunday, July 05, 2009 19:00 UTC Subject: [amsat-bb] Re: dream your own sat > Rupert, > I think that is a fair assumption on your part, but only because the are > no > new ideas being presented that have commercial potential that can use > Amateur Radio as an inexpensive to proof of concept. > In the present Amateur Radio community only Emergency Communications is > getting the publicity.

[amsat-bb] Re: dream your own sat
The recently launched TerreStar-1 is designed to provides emergency comms capability http://www.southgatearc.org/news/july2009/terrestar_1_launched.htm The basic problem is that Amateurs want linear transponder satellites in orbits above 1400 km in order to provide reasonable DX opportunities and pass times greater than 20 minutes. But "cheap" launches only seem to be available for 500-800 km orbits, so we need to find a way to increase the orbit of say a triple-cubesat from 700 km to 1400 km using a non-combustive technology so as not to upset the cheap launch provider. Providing the radio communications is by comparison a trival exercise it's finding a means (solar powered thrusters ?) to increase orbital height that's the tricky part. 73 Trevor M5AKA --- On Sun, 5/7/09, John B.

Unfortunately, the LEO satellites that > hams can afford generate little interest in this forum. I wish we could some how better influence the dozens of cubesat satellites being built with AX.25 packet comm systems to at least consider a backup digipeater comm system. If just six of these allowed for a possibility of user digipeating, we would have a constellation that would provide worldwide text messaging capability from mobiles and handhelds with delays no more than 30 minutes. What a fantastic emergency comm system we could have. If ten of them were available, then the coverage would be nearly continuous. Amateur Radio needs to recognize its trememdous legacy of over a century of wireless text messaging and our ability to bring that connectivity to the field any time anywhere. We simply need to link them together to meet our overall "Universal Amateur Radio Text Messaging Initiative", that is, any ham, any where, any time, able to text message any other ham anywhere using any hardware device, commercial or amateur by callsign alone. Please see www.aprs.org/aprs-messaging.html I count over 2 dozen existing amateur radio text messaging systems few of which are currently crossconnected. Most talk only within their own constituents. APRS and some others are already cross connected at the email level which then connects to cellphones and other wireless devices. So crossconnecting at the APRS internetwork or at the email level is easy to do. We just need all authors to consider transparent cross connection as a goal as per the above web page. This has already been done for all APRS satellites and even the ARISS system when it came over the the Satellite APRS channel 145.825. When ARISS is in packet mode, it enables text messaging and Email to and from the front panel of any APRS radio in the world via our existing network of APRS ground stations. See the downlinks on www.ariss.net We have tried to get other packet satellites on that channel, SUNSAT, PCSAT1, PCSAT2, ANDE, RAFT and ISS all of which supported this universal text messaging. We need more, and longer lived satelites. And most any AX.25 cubesat could do it as a secondary mission. We need to look for opportunities there. We had GO32 also for a year or so until its recent demise, though it's frequency was different. Bob, WB4APR ___ Sent via amsat...@amsat.org. Opinions expressed are those of the author.

[amsat-bb] Re: dream your own sat
Hi Trevor, I'm really keen on exploring just how realistic it is to place a "orbit modifying" system on a 3U CubeSat or a satellite the size of AO51. A lot is being presented to the CubeSat community about the possibilities of using the lower cost launch to get to LEO and then "slowly" modify the orbit to an elliptical MEO - using "safe" plasma or ion propulsion. David Bowman, G0MRF, presented a great paper at the October AMSAT 2008 Symposium which went into details about how it might be done and a survey of the propulsion options being worked on. Much of that paper's background can be found on David's web site at: > http://g0mrf.com/MEOSAT.htm (Get a copy of the AMSAT 2008 Symposium papers for his updated presentation) At the CaL Poly 2009 CubeSat workshop, the following two papers were presented on the subject of satellite propulsion. > http://mstl.atl.calpoly.edu/~bklofas/Presentations/DevelopersWorkshop2009/1_New_Tech_1/4_Scharlemann-Propulsion.pdf > http://mstl.atl.calpoly.edu/~bklofas/Presentations/DevelopersWorkshop2009/1_New_Tech_1/6_Biddy-Monopropellant_Propulsion.pdf Are there any AMSAT volunteers out there interested in the technical challenge of creating a team to help turn these interesting ideas into flyable hardware?? I'm sure that this could also turn into a great commercial opportunity for you entrepreneurs out there. I firmly believe it's an "obvious" technological direction to take, if we are to "economically" move out of the LEO orbits. Again - anyone interested in moving talk into action?

[amsat-bb] Re: dream your own sat
I had an idea of setting up a pager network. That could be used for national or local emegrancy. Or just about anything else for that matter - my orignal idea was for national and local emegrancy, dx reports, and weather. With the added bonus of a personal I'd for yourself. There is a man in MI doing this with his APRS group and emegancy coms now. My idea what and is slightly different from his. I could interconnect systems or not. I like the idea of being able to text any call sign by just knowing the call sign - I never done it but doesn't DStar offer a way to do this? I know the dstar system will route you to the last place it heard a call. If you wanted to direct it to do so It would or shouldn't be too hard to setup a way for someone to know the call and have it routed to a pager. Of course then you would have to say something like get on your radio or something. Since it is one way. But it could work It is still an idea but at this point it is just an idea. I moved the idea to a collabration site, not in front of my computer and for the url - I have a link to on either http://www.HamOhio.com/profiles/kd8bxp Or http://73s.org/kd8bpx (look for the blog listed is this legal or something like that) LeRoy, KD8BXP http://www.HamOhio.com Sent on the Now Network� from my Sprint® BlackBerry -Original Message- From: "Bob Bruninga " Date: Sun, 5 Jul 2009 18:01:25 To: John B.
