ABSTRACT:
A mobile satellite communication system includes an antenna assembly mountable on a vehicle and a satellite tracking assembly. The antenna assembly includes an antenna device for receiving first satellite signals from a first satellite in a first frequency band and for transmitting and receiving second satellite signals to and from a second satellite in a second frequency band, and a drive subassembly for rotating the antenna device relative to the vehicle in response to a control signal. The satellite tracking assembly maintains the antenna device pointed at the first and second satellites as the vehicle moves. The system further includes a receiver coupled to the antenna device for receiving the first satellite signals and a transceiver coupled to the antenna device for transmitting and receiving the second satellite signals. The first satellite signals may be video and imagery data signals transmitted in the Ku band by a direct broadcast satellite. The second satellite signals may be two-way digital communication signals transmitted and received in the L band by an AMSC satellite.
