In the range test of anti-ship missile,the missile’s flight height can be obtained by telemetry equipment on the missile.This elevation data are be used to calculate missile geodesic distance by coordinate transformation,and the positioning method of airborne infrared theodolite single station is realized.The influence of the difference in elevation and geodesic distance of airborne infrared theodolite station and missile on single station positioning accuracy is analyzed,and single station positioning accuracy of airborne infrared theodolite and intersection positioning accuracy of two airborne infrared theodolites are estimated by Monte Carlo simulation.The simulation results show that for sea low altitude anti-ship missiles with the geodesic distance of several thousand meters,single station positioning accuracy and two-station intersection positioning accuracy are of same level.And single station positioning accuracy for missile missing distance measurement is more than one times higher than that of missile positioning.
