Abstract:

In this paper, the theory of the parallel system is used to investigate artificial modeling, computational experiments and parallel execution for global navigation satellite system (GNSS) control and management. A parallel framework of GNSS is introduced firstly, and the key techniques of artificial modeling of the GNSS parallel system are analyzed, and an Agent based modeling approach is proposed. According to the need for computational experiments, experimental methods and flowcharts of experiments for artificial modeling, experimental support and operational maintenance of GNSS parallel system are designed, and operation mode of the GNSS parallel system and its parallel execution process are addressed. Finally, the applications of our approach are given, in which the example of GNSS parallel system used in operators′ training is demonstrated. The research results show that the GNSS parallel system can be used to improve the development and operational maintenance of actual GNSS.
