| 中文摘要: |
| 阐述了移动测量系统的定位准确度需求，对圆概率法、均方差法和中误差法三种位置准确度评估方法进行分析比较，并在标准试验场内开展了车载GNSS/INS定位准确度测试。实验证明，中误差法的评估结果最准确，其误差小于1 m，明显优于圆概率法和均方差法。 |
| 英文摘要: |
| The positioning accuracy requirement of mobile measurement system is expounded. The three methods of positioning accuracy evaluation including the circular probability method, mean square error method and median error method are analyzed and compared. The positioning accuracy test of vehicle-mounted GNSS/INS is carried out in the standard test field. Experiments show that the evaluation result of the median error method is the most accurate, and its error is less than 1 m, which is obviously better than the circular probability method and the mean square deviation method. |
