Research of GMR-1 in GEO Satellite Mobile Communications
Abstract:
At present, technology related to GEO is wide used in the civil and military fields. In this paper, firstly, the generation of GMR-1 was introduced and then a detail illustration of how to comprehend the GMR-1 system and its structure was made by comparison between GMR-1 specifications and GSM standard. These two specifications were compared in terms of the physical channel, logical channel, bursts, mapping and so on. The analysis indicates that GMR-1 modified the lower layers for the satellite channel. In the end, we are looking ahead to the future of the GMR-1.
