AMSAT News Service Bulletin 102.05 From AMSAT HQ
SILVER SPRING, MD. April 11, 2004
To All RADIO AMATEURS
BID: $ANS-102.05
Rick Hambly, W2GPS, AMSAT Executive Vice President and Board of Directors
member recently answered some questions about AMSAT's upcoming high Earth
orbiting satellite project Eagle.
Q: I put together a pretty decent S-band downlink for AO-40, and had great
results! I really enjoyed U/s operation but am not in a position to build an
L-band uplink at this point. Will U/s be included on Eagle?
A: It's to soon to say for sure what will be on Eagle, but I would expect
Mode U/s will be accommodated to support all those who have invested in this
mode for AO-40. One of the experimental modes that can be activated on Echo
is Mode U/s (FM voice and data only) but that will be a challenge due to the
high Doppler shift and the rapid movement.
Q: Will Eagle have fixed transponders or a matrix such as was used on
AO-40?
A: The current state of Eagle's design includes a matrix so any
receiver can be connected to any transmitter. The design is not finalized
and I expect there may be at least one exception to this, the mode C/c
transponder (see the C-C Rider article by W3IWI in the 2003 Proceedings).
[ANS thanks Rick, W2GPS for the above information]
