Abstract:

At present,the demand of large-scale public application to BeiDou high precision navigation and location service is increasing.To solve this problem,the key technology flow of BeiDou high precision positioning data processing and network broadcasting is proposed.Based on the foundation enhancement system of the BeiDou foundation of Sichuan province,the high precision positioning data broadcasting system based on the network mode is designed and realized by the message queuing technology,so as to provide real-time and dynamic high precision data broadcasting service for massive users.Test results show that,the positioning accuracy of the proposed positioning system is less than 0.7 m and the height accuracy is less than 1.5 m.

Key words: BeiDou satellite navigation System (BDS), high precision, positioning, data processing, broadcasting
