Abstract
In order to initially establish burst acquisition in a TDMA satellite communications system, at least one of multiple earth stations (a first station) is controlled to instruct one of the other earth stations (a second station) to transmit an acquisition signal. The acquisition signal is transmitted in a continuous manner and has lower power than normal or full power. The first station receives the acquisition signal transmitted via a satellite transponder and detects a reference time point included in the received acquisition signal. Thereafter, the first station obtains a time difference between the reference time point and a received reference burst time point. The time difference intelligence is sent to the second station, which in turn transmits a burst at a time point determined by the transmitted time difference information.
