Paper Title:
Research on Passive Location Based on the Least Square Estimation Method
  Abstract

Passive location system does not radiate electromagnetic wave, so it can work passively and conceal itself very well. Main factors interfering location precision are: measure errors of time difference, measure errors of three satellites, height errors of targets location on earth, geometry form of satellites cluster and orbit height of satellites cluster; The Least-square estimation method is presented, at the same time in the process of algorithm iteration the target height can be inquired in the geography information system and be corrected continuously, and the localization error is analyzed and simulated, the result indicates that the corrected height error can improve the height precision, then improve the level precision, The integral localization precision can be improved.
