A communications system, a communications station, a method of controlling
the power to transmitters in a communications station, and a storage
medium storing instructions for controlling power to a communications
satellite. The power consumed by each transmitter is determined, and
desired power settings are determined. The power consumed is compared
with the desired power settings. If the power settings are not proper,
then it is determined whether the desired power is available. If so, then
the power settings are adjusted. If not, then load priorities of the
transmitters are determined, and if there is sufficient power to provide
for the determined load priorities, the power settings are adjusted. The
communications station includes variable gain amplifiers (26-1, 26-2, . .
. 26-n), to provide intermediate signals; high gain amplifiers (28-1,
28-2, . . . 28-n) for amplifying the intermediate signals to output
signals; monitoring power supplies (36-1, 36-2, . . . 36-n) for
determining the power provided by the high gain amplifiers, and a power
profile processor (32) for adjusting the gain of the variable gain
amplifiers.
