| Abstract: | Based on the principle of time-difference location,accuracy model of target location is deduced.The relationship between accuracy of target location and orbit altitude,orbit altitude difference,satellites' formation configuration,target position,Time Difference of Arrival(TDOA)accuracy,relative satellite position accuracy,absolute satellite position accuracy and measurement accuracy are analysed.Some significant conclusions are obtained from simulated results. |
