卫星自主完好性相关峰监视

Resume of Satellite Autonomous Integrity Correlation Peak

卫星自主完好性监测(SAIM)技术是地面完好性监测手段的重要技术补充,可以有效缩短告警时间,有助于从根本上提高完好性性能。从SAIM技术出发提出多通道相关峰监测算法,实现多点异步采样,恢复相关峰。通过MATLAB软件仿真验证算法并给出典型异常模型及监测结果,并用普通接收机验证工程可实现性。通过软件仿真和实测结果对比论证了方法的可行性,采用成熟的商业星载接收机进行软件修改有效地降低了卫星完好性接收装置的研发难度。

Satellite autonomous integrity monitoring（SAIM） technology is the important means of surface integrity monitoring technology supplement,it can effectively shorten the alarm time,fundamentally improve the integrity performance.From SAIM technology proposed multichannel correlation peak detection algorithm,realizes multi-point asynchronous sampling,restoration of correlation peak.The MATLAB simulation results demonstrate the algorithm and give several anomaly model and monitoring results,with average receiver to verify the project realization.Through the software simulation and the comparison of test results prove the feasibility of the method,using mature commercial satellite receiver software modification effectively reduces the satellites integrity receiving device research difficulty.
