星基增强系统数据仿真平台设计

摘要
针对实测数据难以支持星基增强系统进行完好性监测能力验证的问题,提出一种数据仿真平台设计方案,可以输入实测数据,并根据用户配置的参数添加各类完好性故障事件。仿真结果表明,该平台可准确有效地在观测值中加入各类完好性故障,包括空间信号故障、监测站故障和传播段故障,实现预期功能,为我国BDS SBAS完好性监测能力的验证提供参考。
Aiming at the problem that it is difficult to to support the verification of the integrity monitoring capability of the satellitebased augmentation system for the actual measured data, the paper proposed a design scheme of data simulation platform, by which the measured data can be input and various fault events of integrity can be added according to the parameters configured by the users. Simulation result showed that the platform could accurately and effectively add various integrity faults to the observations, including space signal faults,monitoring station faults and propagation section faults, and achieve the expected functions, which would provide a reference to the verification of integrity monitoring capability for Beidou SBAS.
