A Framework of Parallel Control and Management for Global Navigation Satellite System

Abstract

A Global Navigation Satellite System (GNSS) is intrinsically a complex system that covers many technical fields. The control and management of a GNSS, one of the most important issues to provide and ensure the specified service performance, involves with navigation satellites, operational control system, as well as the system operators. A new and effective method to increase the efficiency and reliability of GNSS control and management is to build the GNSS parallel control and management system based on the ACP (Artificial Systems, Computational Experiments and Parallel Execution) approach which developed in study of complex systems. This makes it possible to conduct various experiments which are either impossible to carry out using actual systems or need tremendous time and resources to complete, and offer low cost and risk as well. This paper focuses on the parallel systems for GNSS based on ACP approach, analyzes the feasibility of constructing the artificial system which is consistent with realistic control and management of actual GNSS, and describes the methods and key technologies for modeling, analysis, and operation with artificial system, computational experiments, and parallel execution. The paper also describes some potential applications of the parallel systems for GNSS based on ACP approach. Combining the artificial system with the actual GNSS, a set of experiments can be achieved for the technical upgrading of actual GNSS, analyzing anomalies and predicting states of the actual system, establishing and amending routine management regulations, training operators and administrators.
