Onboard Gps Dynamic Positioning Technology

The GPS technique used for the high accuracy measurement of the outside ballistic track provides an unprecedented technique support in outside trajectory designing, checking and revising for the trajectory fights battle weapon and precision attack military tactics weapon, and improving the weapon fights accuracy. This paper mainly tells about the GPS dynamic positioning technique on weapon. First,according to the inherent property of the weapan, it puts forward design requests of the GPS antenna on the weapan. Then using these design requests, it designs a kind of loop patch antenna which is carried on the weapan.. It has been simulated with the software named HFSS, and the result of the simulation is very well. Then it introducs the general kind of the GPS dynamic positioning arithmetic and the gray theory. Using the gray theory to fix the GPS dynamic positioning, it forms a new arithmetic. With the programming and simulation using the Matlab, it shows that this arithmetic has efforts on improving the precision of GPS dynamic positioning.
