Location Precision Analysis and Error Correction of Loitering Reconnaissance Munitions

When loitering reconnaissance munitions is conducting battlefield surveillance and target location, measurement errors of inertial navigation system make the target position obtained by reconnaissance equipments be fault. In this article, the reasons for the errors were given, and location errors of reconnaissance loitering munitions were analyzed, an error revising method was also proposed to revise the large measurement error made by inertial navigation system based on landmark information. Simulation results show that the algorithm can effectively correct measurement error and improve target localization accuracy.
