| In order to make weapons to achieve the goal of long-range, accurate, and efficientdamage and low collateral damage, so as to transform from the repression by the surfacetarget to the destruction by the point target.Therefore, there is an urgent need to use highdynamic precision-guided receiver. However, because the actual experiment demands thereceiver’s performance particularly high and testing the performance of the precision-guidedreceiver will cost a lot of manpower and resources. Thus, there has a very important practicalsignificance to study the indoor navigation simulator which based on the precision guidancewhen testing the receiver.This article is arm at the receiver can achieve the performance requirements of fast andstable positioning，the receiver’s acquisition and tracking performances change insignificantlywhen the carrier changes the movement mode. Mainly on the basis of the original simulator，through the PC control, and real-time detected the receiver. According to the Precision-guidedGPS navigation signal simulator system components，descriped the functionality, workingprinciple and implementation of hardware and software in details. Analyzed the structure ofthe GPS signal, and its Location Principle;Accomplished the PC control software withmulti-serial port, and analyzed the function and effect of each display module. In addition,and introduced the parameters’calculating method of each module in detail. Focused on themethod of coordinate transformation in the simulator’s positioning solution;in order to test thehost computer software，set up the hardware platform of the simulator and the receiver，increase PCI215 digital I / O card to send INS auxiliary information to the receiver in thesystem through the synchronization host，so that improve the dynamic performance ofreceiver;Analyze and test the signal quality and performance of navigation signal simulators,given the results of the test. Test the receiver of aquirsition and tracking performance. |
