摘要:

应用平行系统理论,研究全球卫星导航系统(GNSS)人工建模、计算实验和平行执行的方法。首先构建GNSS平行系统框架,分析GNSS平行系统人工建模的关键技术,提出基于代理(Agent)的导航系统实体建模方法;然后根据计算实验需求,设计GNSS平行系统在人工建模、试验支持与运行维护等方面的计算实验方法及流程。在此基础上,给出GNSS平行系统的运行模式及其平行执行过程。最后,以GNSS平行系统在人员培训方面的应用为例,说明GNSS平行系统在实际GNSS运行维护方面的应用。研究结果表明,建立GNSS平行系统是提高GNSS建设和运行维护效率的有效方法。

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.

Key words: GNSS, Parallel system, Experimental support, Performance assessment, Operational management
