摘　　要：双星定位系统是具有快速定位和简短报文通信功能的卫星定位系统。在研究其定位原理的基础上,建立了双星定位系统的误差模型和仿真系统,并对仿真系统的硬件结构、仿真软件和仿真方法进行了介绍。该仿真系统可以模拟双星定位系统大多数的工作环境和工作状态,并且可以对双星定位终端产品的各项技术指标进行定量测量。解决了定位终端的技术指标在实际系统中测量难的问题,对双星定位终端的研制有一定的参考意义。Radio Determination Satellite Service （RDSS） is a system that can provide accurate subscriber positioning and short message service to thousands of subscribers by using two geostationary satellites. Based on the research on the positioning theory of RDSS system, a positioning error model was established and a simulation system was developed. The hardware architecture, the simulation software and the simulation method of the RDSS simulation system were also proposed. In the simulation system, most of the operating conditions and operating states of the RDSS system can be simulated and most of the technical parameters of the RDSS positioning terminal can be measured easily. The presented RDSS simulation system can greatly benefit the development of the RDSS positioning terminal.
