GNSS (Global Navigation Satellite Systems)/INS ( Inertial Navigation Systems) has been the research hotspot in the field of navigation and positioning. while the small-area densification of 5G communication technology and the technical means of large-scale array antennas have provided new developments for integrated navigation research. The GNSS/INS integrated navigation mode was introduced in this paper, the research status of integrated navigation at home and abroad was investigated and analyzed, several improved Kalman filter algorithms were described: unscented Kalman filtering algorithm, adaptive improved algorithm, neural network improved algorithm, deep learning improved algorithm. GNSS/INS/5G integrated navigation system was discussed. Finally, the application prospect of integrated navigation system was given in location service.
