For the realization of large coverage, high precision, dynamic requirements of UAV navigation system, this paper studies the data calculation method in CNSS/GLONASS integrated navigation and positioning from the status quo of UAV navigation. Based on the “current” statistical model, it establishes the state equation and observation equation, and verify the performance through flight experiment and data analysis. The result shows that the CNSS/GLONASS integrated navigation location data calculation method can realize complementary advantage of two systems, improve usability of Beidou satellite navigation system in UAV high dynamics navigation and enhance navigation accuracy.
