高精度导航接收机自动测试系统设计
Design of Automatic Test System for High Precision Navigation Receiver
摘要
Abstract
Aiming at the problems of large error,poor repeatability and low degree of automation of existing navigation receiver test schemes,a high-precision navigation receiver automatic test system is designed.Firstly,the hardware platform of the receiver test system is constructed,which is composed of multi-system navigation signal source,high-performance industrial computer,program-controlled power supply,network switch,serial port server,etc.Secondly,the signal source simulation control software is used to control the multi-system navigation signal source to simulate and produce specific navigation signals,which provides a simulation environment for the test of high-precision navigation receiver.Then Visual Studio is used to develop the navigation terminal automatic test and evaluation soft-ware,and the ranking evaluation method and root mean square evaluation method are proposed as the evaluation criteria of receiver posi-tioning accuracy.Finally,the reliability and stability of the test system are verified by experiments,and the test system can test the per-formance index of the high-precision navigation receiver accurately and quickly.关键词
