Abstract
Satellite navigation system is an important infrastructure in modern society and is widely used in many fields. With the increasing requirement for positioning accuracy, especially in emerging fields, current systems still face challenges in complex environments and high-speed motion states. It is of great significance to study and improve the positioning accuracy. This paper discusses the methods and techniques to improve the positioning accuracy of satellite navigation system, analyzes the research status and technical trend, summarizes the basic principles, and analyzes the factors affecting the accuracy. In view of these problems, suggestions are put forward to optimize signal processing, enhance receiving algorithm, multi-frequency signal processing, improve technical standards and compatibility, strengthen infrastructure construction, optimize satellite layout, and innovate algorithm and data utilization. Through these technical means, it is expected to provide effective solutions for improving the positioning accuracy of the satellite navigation system, and to promote its high-precision application in more fields.
