Research on Authentication Method of Satellite Navigation Signal Based on Digital Wireless Communication System

The quality, safety, and reliability of satellite navigation signals will directly affect the vital interests of users and consumers, and affect the safety of their application industries. Certification is a means of considering the quality level of products and the relevant capabilities of manufacturing enterprises. From the perspective of product testing, certification testing is the testing of the overall performance and functional indicators of a product, which is more accurate, comprehensive, and reliable compared to general product inspection or testing. This article elaborates on the interface, channel, and process design of digital wireless communication systems, explains the design principles of satellite wireless network communication systems, and provides authentication requirements and methods for satellite navigation systems. Practice has proven that this method meets the standard requirements for satellite navigation certification and can be promoted in production practice.
