Data Compression Algorithm Based on Beidou Navigation Satellite System
The traditional general aircraft positioning navigation and communication system usually uses GPS positioning navigation system,radio and other means.But the station has problems such as high cost and poor coverage in remote areas.In recent years,with the successful networking of Beidou navigation satellite system with fully independent intellectual property rights,the cooperation of various related industries has gradually become active.The Beidou passive positioning function is used to obtain location information,and the Regional Short Message Communication function is used to achieve communication function,so that the positioning,navigation,monitoring,scheduling,communication and other functions of the general aircraft are not restricted by the region.Due to the limitation of short BDS packets,the reporting interval is too long and the amount of location information data sent once is too small.The article develops a data compression algorithm based on Regional Short Message Communication function,which can compress data and increase compensation points to solve these problems.
