PROBLEM TO BE SOLVED: To improve a weapon system for providing hot start navigation information for a satellite using positioning system receiver of a missile before a flight, by eliminating a part of cost and disadvantage in an advance technology. SOLUTION: This weapon control system provides the hot start navigation information for the satellite using positioning system receiver of the missile before a flight. This system has the satellite using positioning system receiver for decoding a P(Y) signal from one or a plurality of satellite using positioning system constellations of satellites, by using a classified red cipher key. When the P(Y) signal is decoded once, one or a plurality of characteristics (for example, PRN code synchronization, a Doppler shift and a modulation bit sequence) of the signals is derived. Next, the other information of a black cipher key including the characteristics and the red cipher key of these signals, is provided for the satellite using positioning system receiver of the missile before a flight. This information is provided for the missile, and the missile can acquire the P(Y) signal, and thereby, the missile can quickly determine its position more quickly than the other method.
