Modeling and simulation in RDSS system

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.
