摘　　要：根据卫星导航接收机的应用领域,利用卫星信号模拟器针对导航型接收机动态定位准确度、测速准确度、测向准确度三个主要指标制定了测试方法,并构建了一套评估工具。该工具能够在单次测试完成后输出上述三个指标的统计评估结果,统计评估结果包含均值、方差、圆概率误差等多项参数。研究结果表明,该测试方法及评估工具能够快速、有效地完成卫星导航接收机动态性能的校准。According to application fields of GNSS receivers,measurement methods and an evaluation tool have been developed tomake a comprehensive calibration of GNSS receiver. By utilizing GNSSsimulator, accuracy of dynamic positioning, speed and course could becalibrated. Statistics evaluation results of above-mentioned three accuracyindexes could be outputted after finishing a single test, which includemulti parameters such as mean value, variance, circular error probable andso on. The research results show that the evaluation methods and tool areable to make the calibration of GNSS receivers in fast and effective ways.
