Abstract
Single satellite passive location has many advantages and practical applications, but it also has limitations such as the positioning is not accurate and the sample points of track are relatively sparse. Knowing the shortcomings of such single satellite positioning measurements, this paper gives the simulation of a three-point passive location method based on joint Time Difference of Arrival (TDOA) and Frequency Difference of Arrival (FDOA) and analyzes the Geometric Dilution of Precision (GDOP) performances based on positioning error. The simulation results show that this method is able to calculate the position of radiation source with TDOA and FDOA measured at three points. GDOP performances show the relative velocity and position between radiation source and satellite can affect positioning accuracy in the range of TDOA and FDOA estimation error.
