This paper presents an integrated INS (Inertial Navigation System) and camera-based
navigation system. The camera-based navigation system provides position measurement
aiding to the INS. This is an alternative to the more conventional GPS (Global Positioning
System) aided INS. The system is intended for UAVs (Unmanned Aerial Vehicles) and long-range missiles. The basic principles of camera-based navigation are presented. The Kalman
filter based integration of INS and camera-based navigation is discussed. Total system
simulation results are shown together with INS simulations for comparison. Finally, a brief
overview of factors that improve the navigation accuracy is presented.
