【Abstract】 In this paper, the locations of ground targets by satellite borne remote sensors were deeply explained. The azimuth of target relative to the nadir point locus of the satellite and the sensor’s reviewing angle were acted as result parameters in relative location processing. Through these parameters combined with the orbit parameters, the general formulas of the latitude and longitude of the ground target were derived. On this basis, the target’s position errors were analyzed completerly, the calculation methods of error components were discussed in detail, and a corresponding calculation formula was also derived.更多还原
