Modeling and Simulation of the Passive Regional Satellite Navigation System
The passive regional satellite navigation system (PRSNS) becomes a significant topic for civil and military services due to the limit of outlays and geography factors.The research on the modeling and simulation (M&S) of PRSNS is to study the key technology and operation principle.The paper discussed how to build up the simulation system of PRSNS.The system included satellite constellation,tracking station,data processing center (DPC),feeding station,users application,information management,surveillance and visualization,etc.And the system is divided into two major logical parts and three physical layers to reduce the dependence among the components in order to quicken the programming process.As an example,a simulation system of PRSNS is constructed,which adopts a satellite constellation that is composed of geostationary earth orbit (GEO) satellites,inclined geosynchronous orbit (IGSO) satellites and median earth orbit (MEO) satellites and covers the Pacific-Asia,Indian Ocean and Middle East.The efficiency of the simulation system and the feasibility of PRSNS are verified by simulated static positioning and dynamic navigating.
