This work discusses the feasibility of applying a small and inexpensive GPS, a Field
Strength Meter (FSM) and a personal computer, that can activity and rapidly determine
the Geo-locations of RF cooperated emitter, which have a wide range of both m
ilitary and
civilian applications.
The emitter’s Geo-coordinates can be estimated by a single moving observation
system, which receives signals from the emitter, and measures his Geo-locations and Field
Strengths of the transmitted signal at four Positions
Analytic Formulas are derived to calculate the location of Emitter, which detected
from four Positions by using of Linear Algebra or pseudo range’s solution, The MATLAB
was used to solve the four Equations and to simulate the Geo-Positions on Geo-Map.
