Indian Small Satellite Systems Conference -1
Hi All A week late , sorry thought I had posted it here but heres the report.
Amsat India was invited to attended the Indian Small Satellite Systems Conference -1 conducted 28 April 2010 , at ISRO Bangalore. Amsat India was represented by Ganesan ( our Hamsat 2 designer) and myself VU2POP ISSSC was a one day programme from 9 am to 5.30 pm . It was very interesting and as many papers were presented & topics discussed the time was short it got over by 7 pm. One day is too short and hopefullu next year it will be 2 days. However we thank ISRO for kickstarting a very interestng platform for interaction of ISRO with various educational institutions including Amsat India who are into ham satellite projects.
Important topics were on the current Small satellite develpoments and the future trends of small satellites including Mini, Micro, Pico sats etc. Hamsat VO-52 too falls into the small sats, to add many students all over the world have been building student sats as projects and in India too, nearly 26 Universties have got into building student sats with various payloads. Most Ednl. intitutions already have a ham club and some institutions are now setting up ham clubs in their institutions to help learn more of ham satellite operations and facilitate building ham band payloads. As of now most of them are either digital with only beacon downlink and no voice transponder. In the next couple of months you will find many cube sats etc with experimental payloads launched.
Amsat India has 2 linear tranponders ready and we Amsat India are asking ISRO for a higher orbit to cover a larger foot print and longer pass duration. Its no use having another LEO as HAMSAT 1 Hamsat 1 will be celebrating its 5th birthday on 5 May and ISTRAC has been monitoring its health and its utilisation, they report that Hamsat 1 is in good health and should serve the hams for many more years. In this regard there was an email by VU2WMY Mani a few days ago asking for USER feedback like utilisation & experiences by hams all over the world with Hamsat 1 Please send in your reports , utilisation and experiences with Hamsat by email and the same will be forwarded to ISRO.
Looking forward to all your reports comments. We would like to thank ISRO for the HAMSAT 1 and we look forward to HAMSAT 2 Finally we thank Programme Dir and Project Director - Small Satellite & Uppagrah Amateur Radio Club for the kind invitaion to particpate in the ISSSC-1 and we look forward to many such platforms for the development of small satellite systems with the participation Educational Institutions & Amsat India.
Best regards Pop VU2POP Dir Technical Amsat India
Hams who attended VU2WMY, VU2GDX, VU2RVJ, Ganesan , Chandraskar new hams & myself VU2POP.

Hi All

Best regards Pop VU2POP Dir Technical Amsat India
Hi Pop, VU2POP
I am very happy to know that AMSAT India plan to launch a new satellite with 2 linear transponders in a higher orbit covering a larger foot print in comparison of the actual VO-52
VO-52 continually operating with its linear transponders during all available orbits is a reliable satellite for the amateur radio satellite communications and as well for educational purposes.
Congratulations to Amsat India and to ISRO

With a little more "push" is it possible to have just a slightly elliptical orbit? I don't know what brand of batteries they put in VO-52 but they probably put a small pink rabbit in it as they don't seems to bother too much with their power budget...
What's is funny is the commenting on the perf board model AMSAT-India was showing couple of years before the launch of VO-52, some where commenting on the jumper wire perf board modelling as if it was not something who will never be able to work...
AMSAT-INDIA just doing an excellent and professional job on VO-52 they even put 2 transponder in the same satellite "too strong never broke". I'm convince their new orbit will cover quite some area on earth..

If you carefully read, AMSAT-India has 2 Linear-Transponders ready and not a satellite. As you knows, the satellite VO-52 itself was built and contributed by ISRO to AMSAT-India.
If you want a satellite in HEO then support Phase-3E from AMSAT-DL.

I might have missed something, Thomas, but I believe Luc recommended a 'slightly elliptical orbit', not necessarily a HEO one. Do these need to be the same thing? An elliptical MEO would allow for periods of more challenging operation with better opportunities for DX alternating with periods of lower pass loss, but smaller footprint. This might well be something that AMSAT-India could come to ISRO to ask for.
Of course, none of this takes away from the excellent work of AMSAT-DL on P3E, which we all eagerly support.

Exactly Bruce
The 4 key words are: With a little more "push" and 'slightly elliptical orbit'
This will not replace in anyway an HEO the ultimate goal but in the mean time a MEO will give us some releif of our dull environment.
P.S. Dull in the sense of the same usual earth path!

Hello Bruce
I missed also something of this discussion. I'm only a digest-reader of the AMSAT-BB mails. Sometimes its a problem for me when Luc copies fragments of discussions into the EU-Amsat group.
Domenico's mail was irritating. AMSAT-India does not plan to launch a new satellite, they are looking forward, if ISRO would be so kind to offer a new satellite structure for their 2 transponders and a launch into a higher orbit. I wish the OM's from AMSAT-India good luck and success for this project.
I'm not a specialist for orbits and rocket launches, but every orbit is better than a LEO-orbit. I'm aware of that such launches are much expensive than a LEO-launch. There were thousands of discussions about HEO-satellites, but Luc wrote a very important thing. If we all AMSATers do not pull at the same string, we would never have such a fantastic satellite like P3E in a HEO. I hope my fellows from AMSAT-DL have anyhow success with P3E and the cooperation with DLR (www.dlr.de).
Thank You for your support of AMSAT-DL.
