<p>PROBLEM TO BE SOLVED: To provide a weapon guide system in which total accuracy error is reduced. SOLUTION: The guide system 10 includes a large number of GPS satellites 12-18 transmitting a GPS data to a ground sensor 20. The ground sensor 20 comprises a GPS receiver 24, a self-searching computer 28, a data formatter 30, and a transmitter 32. The GPS receiver 24 receives a GPS data and determines a second position of ground sensor based on the GPS data. The self-searching computer 28 determines the first position of ground sensor 20 based on the GPS data collected with time. The first position is more precise than the second position. The data formatter 30 determines the GPS error between first and second positions transferred from the transmitter 32. Since the GPS error substantially enhances the accuracy of a guided weapon 40 in delivery, it is used by the guided weapon in the neighboring area of ground sensor 20.</p> |
