Open publisher page 2 citations

Abstract

Based on the principle of TDOA/FDOA location,an accuracy model of target location is deduced.The relationships between accuracy of target location and error sources are discussed,such as orbit altitude,distance between two satellites,TDOA(time difference of arrival accuracy),FDOA(frequency difference of arrival accuracy),measurement accuracy of velocity and satellite position.It is shown that FDOA and measurement accuracy of velocity are the crucial factors,and TDOA and measurement accuracy of satellite position are secondary.
