Radar detects the targets and measures its parameters, range, azimuth, height, and velocity of the target. In some application, such as early warning radar we don’t have extremely measure all these parameters, but in other application like detection targets and measures his geo-locations requires high resolution to all these parameters. This paper discusses the feasibility of detecting the location of from four deferent satellites Positions by using of Linear Algebra and pseudo range’s solution, The Matlab was used to solve the four Equations and to simulate the Geo-Positions on Geo-Map
