Abstract

Along with the development of navigation modernization concept, the system safety and the integrity have become the key performances of the GNSS. This paper discusses the connotation and the composition of the system safety from the perspective of navigation warfare. Combined with the construction of the BeiDou system, this paper reviews the key breakthroughs and research achievements in the design of the signal system, the frequency planning and coordination, the construction of the anti-jamming architecture, the inter-satellite link and integrity monitoring. Finally, the future development of the satellite navigation system is discussed.
