Research on Maintenance and Support Technology for Offshore Based on Beidou Satellite Navigation System

Beidou satellite navigation system can provide positioning, navigation, timing and short message communication services for ship users. In this paper, according to the requirements of the maintenance and support of ship equipment in the open sea, based on the information transmission channel of Beidou navigation satellite system, the transmission data volume is compressed by using the method of equipment status and fault coding, the remote reproduction of ship equipment status and remote guidance of fault maintenance are realized, so that the equipment maintenance support field extends to the open sea, which has strong practicability.
