摘要: 针对中国北斗卫星导航系统(BDS)用户设备动态性能的检测需求,本文设计了一种可以在真实环境下,高效、自动化测试的检测系统,称为BDS高精度动态检测系统(BDHDS)．该系统以依维柯汽车为载体,高精度的惯性组合导航系统为测试基准,布设了卫星信号采集回放仪、卫星信号转发器、测试暗箱、监控设备等专业测试设备,并且基于JavaScript开发了自动化测试评估软件,实现了卫星信号采集、回放，测试结果实时显示，测试报表自动生成、测试过程记录等功能．为了检测BDHDS的有效性,本文选择了两种不同型号的BDS设备分别进行了静态、低速动态和高速动态跑车试验,试验结果表明该检测系统能够直观高效地评估BDS用户设备的动态性能．Abstract: In order to detect the kinematic performances of BDS user equipment, a detection system are designed which can efficiently and automatically test the kinematic performances of BDS user equipment in real environments. It is named BDS High-Precision Kinematic detection system (BDHDS). This system uses Iveco as a carrier and a high-precision inertial integrated navigation system as a test datum. It consists of professional test equipment such as satellite signal acquisition and playback, satellite signal repeaters, shielding boxes, and monitoring equipment. It also develops automated testing software based on JavaScript. The BDHDS has such functions as satellite signal acquisition, playback, real-time display of test results, automatic generation of test reports, and recording of test processes. In order to test the effectiveness of BDHDS, two types of BDS user equipments are selected for static, low-speed kinematic and high-speed kinematic tests. The test results show that the BDHDS can intuitively and efficiently evaluate the kinematic performance of BDS user equipment.
