ARLA/CLUSTER: Pedido de Relatórios de Escuta do Satélite BEVO 1 ( 437.325 MHz )

[João Gonçalves Costa]

BEVO 1 is a picosat mission of the University of Texas. It is sponsored under NASA JPL's DRAGONSAT program. The mission is to test a GPS unit designed and built in house by NASA Johnson. Texas A&M and the University of Texas were required to build 5" cubesat spacecraft buses and support systems for the GPS units. The satellite will be deployed together with its sister satellite AggieSat2<http://space.skyrocket.de/doc_sdat/aggiesat-2.htm> from Space Shuttle Endeavour (STS-127)<http://space.skyrocket.de/doc_sdat/sts-ov.htm>.
BEVO 1 request for reports

Radio Amateurs are requested to listen out for and report any signals on 437.325 MHz from BEVO1 launched July 30

BEVO1 and AggieSat2 were a pair of Amateur Radio satelles originally designated as DragonSat. They were ejected together from the Space Shuttle Endeavour (STS-127) but it appears that they failed to separate.

Karla Vega KE5FKU provides this update on BEVO1:

Still no signals from BEVO1, although beacon packets were heard from AggieSat2.

The current theory on the state of the satellites is that only partial separation occurred. The inhibit switches keeping the satellites powered off have been closed, allowing the satellites to boot up.

However, it is likely that the antennas did not deploy correctly, leaving the antennas disconnected from their respective transmitters.

AggieSat2 transmits with 1W of power so it is easier to hear, while BEVO1 only transmits with 200mW during beacon mode.

Thanks for all your help!
