Research on HLA/TM in GNSS system

The time management service is one of six kinds of services described in high level architecture (HLA) interface specification. The run time infrastructure (RTI) is the particular realization of HLA service interface specifications. This paper first establish the system module and the interaction in the GNSS simulation system, then analysis of the time management mechanism and proposed a time management method for the GNSS simulation system. A GNSS simulation model is presented, which adopts a time management strategy based on time step to complete simulation synchronization and implement the simulation of GNSS effectively.
