摘要/Abstract

摘要： 针对BDS-3系统B1C+B2a及B1I+B3I信号用于单历元RTK快速定位的性能差异不确定的问题,本文在建立BDS-3单历元RTK快速定位模型的基础上,详细推导了BDS-3双频数据RTK单历元双差整周模糊度快速固定算法的实现流程,设计和开发了一种BDS-3单历元RTK快速定位分析软件(SeOTF＿RTK),并比较分析了BDS-3双频数据单历元RTK快速定位的性能差异。试验结果表明:对于B1C+B2a和B1I+B3I数据,BDS-3双频数据单历元RTK快速定位精度基本相当,均可为用户提供厘米级,甚至毫米级的RTK测量精度;对于BDS-3静态数据和BDS-3动态数据,RTK单历元双差整周模糊度快速固定成功率方面,B1C+B2a数据略优于B1I+B3I数据,且均可达到97.5%以上,RTK单历元双差整周模糊度解算效率方面,B1I+B3I数据略优于B1C+B2a数据,且均可优于0.34 s。

Abstract: In view to the fact that the uncertainty of performance differences between B1C+B2a and B1I+B3I signals used for single epoch RTK fast positioning in BDS-3 system.In this paper,based on the establishment of the BDS-3 single-epoch RTK fast positioning model,an implementation flowchart of RTK single-epoch double-difference integer ambiguity fast reslution algorithm for BDS-3 dual-frequency data is decuced in detail firstly.The BDS-3 single-epoch RTK fast positioning analysis software (short as SeOTF_RTK) is designed and developed,and the performance differences of single-epoch RTK fast positioning for BDS-3 dual-frequency data are compared and analyzed.The experiment results show that the positioning accuracy of BDS-3 single-epoch RTK fast positioning is basically equivalent for not only B1C+B2a data but also B1I+B3I data,and both can provide users with millimeter to centimeter level RTK surveying accuracy.For both BDS-3 static data and BDS-3 dynamic data,B1C+B2a data is better than B1I+B3I data in the success rate of RTK single-epoch double-difference integer ambiguity resolution both of which is 97.5%above,meanwhile B1I+B3I data is better than B1C+B2a data in the efficiency of RTK single-epoch double-difference integer ambiguity resolution both of which is better than 0.34 s.

Key words: BDS-3, single-epoch RTK fast positioning, single-epoch integer ambiguity fast resolution, dual-frequency data
