The Design Of Guided Bomb Satellite Receiver's Test Control And Evaluation System

Satellite navigation system gets more attention because of its ability to provide all-weather,high-precision timing and other needs.In the application of missile-borne aspect,due to the vulnerability of the satellite navigation system and the deficiencies in the engineering aspects of the domestic satellite navigation user,the satellite navigation system result some problems,although it is often equipped in the missile to help the navigation system to improve accuracy.This paper firstly introduces the composition of the test system of the satellite receiver,the main function of each part and the test project,puts forward the requirement analysis according to the characteristics of the user.And then,the paper build the template based on the XML script language for the test project and process steps,design automatically test and control system,and also proposes the evaluation system compared the evaluation standard of global navigation satellite system at present.Finally,the paper develops the software of the test control and performance evaluation system using the object-oriented method.Through the test system and evaluation software designed for the satellite receiver of this paper,the coordination and synchronization of each sub-system are kept high,the test efficiency is improved.And the paper studies the testing statistics of the receiver in some specific environment,in order to improve the efficiency of the receiver in the use of air-guided bombs.The real experimental results show that the efficiency of the test system and problem detection are improved greatly,as well as the test method is also provides a new way for the test of the satellite receiver.
