ABSTRACT:
Ongoing communications over radio links between communication stations and subscriber units may be unexpectedly broken. Where the communication stations include low-Earth orbit satellites, communication links are difficult to re-establish because of the timing differential and Doppler-frequency shift associated with the satellite's movement. The communication link is re-established by initially changing the modulation technique in an attempt to re-synchronize the communication station and the subscriber unit. If this fails, the subscriber unit performs an acquisition attempt on another antenna beam of the communication station. If this is not successful, the subscriber may perform an acquisition attempt on antenna beams of another communication station.
