Satellite AO-51

Satellite AO-51 has ceased transmission and is not
responding to commands. The last telemetry data indicated that the third of six batteries was
approaching failure to short, and observations indicate the voltage from three cells is insufficient to power the UHF transmitters. Initial tests with the S band
transmitter were also not positive, although more
attempts are in order. We have tried leaving the satellite in an expected state where if voltages climb high enough, the 435.150 transmitter may possibly be
heard, stated Drew KO4MA AMSAT-NA VP Operations.
