In view of satellite interference location, a precise location model using geographic information system and WGS-84 coordinate was presented, an integrative algorithm using spherical surface for coarse analytic locating and tangent plane for precise iterative locating was therefore proposed, and the theoretical error expression for location method was deduced. According to the location simulation result, when using geographic information system, compared with TDOA error and FDOA error, the location error caused by height error can be neglected.
