Hi All
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.

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.

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.
