摘　　要：本文研究了利用北斗区域系统实现高精度动态定位的观测模型和参数估计方法，给出了数据处理流程，利用TRACK改化软件和实测数据验证了利用区域系统进行精密动态定位的可行性和精度指标。结果表明：北斗区域系统可达到与GPS相当的厘米级动态定位精度，水平方向精度均优于2cm、高程方向优于5cm，结果可为北斗系统高精度测量应用提供有益支撑。The observation model and parameter estimation method for high - precision kinematic positioning with BeiDou regional system are studied in this paper. The data processing flow is given, and the feasibility and precision of the high - precision kinematic positioning with BeiDou regional system is verified using modified TRACK software. The result shows that the positioning precision provided by BeiDou kinematic positioning has reached centimeter level, which is equivalent to that of GPS. The precision of horizontal position is better than 2cm, and the vertical position is better than 5cm. The conclusions of the paper can provide technical support for the application of BeiDou system high - precision surveying.
