Abstract
An initial entry processor (40) for use in a processing satellite (12) in a satellite based communications system (10) is provided having a buffer (62), a detection and timing circuit (64) and an identity circuit (66). The buffer (62) stores an initial entry burst (54) transmitted from at least one terrestrial terminal (14) to the processing satellite (12). The detection and timing circuit (64) detects the initial entry burst (54) and determines a time of arrival of the initial entry burst (54) relative to an initial entry burst slot (52). The identity circuit (66) determines an identity of the terrestrial terminal (14) that transmitted the initial entry burst (54) such that the time of arrival is used by the identified terrestrial terminal (14) during subsequent communications with the processing satellite (12).
