Abstract
System and method for determining an optimal transmission center frequency for a traffic station () in a satellite communication system () includes transmitting, by the traffic station () in a first uplink channel, a first burst of information in a first uplink TDMA frame to a satellite () and receiving, by the traffic station () in a first downlink channel, a downlink TDMA frame including a reference burst () and the first burst of information. A Doppler offset ratio is calculated based on a measured frequency shift of the received first burst of information. A local oscillator offset ratio is calculated based on a measured frequency shift of the reference burst and the Doppler offset ratio. An adjusted transmission frequency of a second uplink channel is calculated based on the Doppler offset ratio and the local oscillator offset ratio.
