The battlefield situation changes rapidly, and the establishment of airstrips can effectively support the take-off andlanding of Unmanned Aerial Vehicles (UAVs) and improve the ability to carry out combat missions.The principles and ability ofsatellite navigation precision approach are introduced, the principles and characteristics of pseudo-range positioning, precisionpositioning, differential positioning and wide-area precision positioning are analyzed and summarized, the common error processingtechniques for point calibration is described, and finally suggestions on the use of point calibration are given, that precisionpositioning services provided by GNSS are the most convenient and efficient strategy are pointed out.Pseudo-range positioning is aguarantee method.For the normal protection area, the monitoring station deployment can be carried out in advance to achieve thereal-time calibration ability of the airstrip.
