BDS Space Signal Monitoring System Architecture and Performance Assessment
摘要
Beidou space signal quality monitoring and assessment is one of the important means to ensure the normal operation of satellite navigation system. It not only provides space satellite status information support for ground operation and control system, but also provides important Beidou service quality information for the general users. In this paper, the Beidou space signal quality monitoring and assessment capability model and system mode, monitoring and assessing processes and architecture, performance evaluation method was proposed. The power spectrum deviation, the correlation loss less, S-curve deviation of BDS based on real data was assessed.
