Beidou Navigation Satellite System Development, Application, and Prospects

The Beidou Navigation Satellite System (BDS), also known as Beidou, is an independently developed global satellite navigation system by China, and it is the third mature satellite navigation system following GPS and GLONASS. BDS, along with GPS, GLONASS, and GALILEO, is recognized by the United Nations Committee on Global Navigation Satellite Systems as a supplier. Comprising of space, ground, and user segments, the Beidou system provides all-weather, all-time, high-precision positioning, navigation, and timing services to users worldwide, with unique short message communication capabilities. After years of development, Beidou has become a significant new type of infrastructure providing global users with all-weather, all-time, high-precision positioning, navigation, and timing services. This paper explores the development, application, and prospects of the Beidou navigation system. The aim is to investigate the positioning accuracy of BDS by reviewing relevant literature, starting with understanding its benefits when applied to satellite navigation systems (such as accurate error estimation and real-time estimation of the receiver's position and velocity). The paper then mentions applications related to accuracy, such as emergencies in tunnels, lunar probe applications, and low-altitude air traffic. Finally, it discusses the prospects and innovations in the direction of BDS. The research method involves querying recent literature on the topic from CNKI for research and comparison. The conclusion is that BDS achieves high-precision satellite navigation positioning through. Based on the accuracy of BDS, it can be inferred that in the future, it will be used in conjunction with 5G technology in daily life.
