| Abstract: | To solve the problem of locating a ground emitter from a constellation,a Doppler frequency difference-based three-satellite passive location method is studied. On the basis of an accurate location model,an iterative algorithm is derived to solve the location equations and the problem of location ambiguity is analyzed. The geometric dilution of precision (GDOP) is theoretically analyzed and verified by Monte-Carlo simulations. The analysis results show that the measurement errors of Doppler frequency differe... |
