Considering the wide application and critical importance of satellite navigation systems, aiming at the requirements for precision and reliability of the next-generation BeiDou satellite navigation system, this study investigates the current development status of integrity technology from four dimensions: basic integrity of satellite navigation systems, integrity of satellite-based augmentation systems (SBAS), advanced receiver autonomous integrity monitoring (ARAIM), and precise point positioning (PPP)integrity, and compares the technical difficulties of each. Finally, it explores the development trends of future integrity technologies. This study is significant for the design and construction of the integrity system of the next-generation BeiDou satellite navigation system.
