Abstract: The GNSS/INS integrated navigation system is a high-precision integrated navigation system that organically combines the satellite navigation system and the inertial navigation system, and takes advantage of the good long-term stability of satellite navigation and the high short-term precision of inertial navigation. The GNSS/INS integrated navigation system is studied. RTK real-time differential positioning has great advantages in application due to its convenient use. Based on the GNSS/INS integrated navigation principle of RTK, a set of low-cost and high-precision real-time integrated navigation system is designed. The integrated application of the navigation system and airborne hyperspectral, experimental results show that the system can provide high-precision position and attitude information in real time, and can meet the application requirements of airborne and other mobile measurement systems.
