摘要
针对卫星导航信号模拟源研制过程中的多体制、多系统导航信号中时空基准的一致性、多系统兼容性数学仿真难题,在分析导航信号结构、特点的基础上,研究了观测量和导航电文的生成方法,并根据多系统参数之间的时间和空间关系,提出了利用时间系统和坐标系统的转换参数解决多系统、多体制信号数学仿真的时空一致性和兼容互操作问题,并对多系统多体制信号的兼容与互操作仿真进行研究。
According to the space-time datum consistency,multisystem compatibility and cooperability of multi system,multi structure satellite navigation signal simulator.Based on the analysis of the navigation signal structure and characteristics,studied the methods of generation measurement and navigation message.According to the relations between time and coordinate system,this paper using consistency to solve multi structure and multi navigation system signal mathematical simulation.And carry out research on the simulation of multisystem compatibility and cooperability.
