摘要
随着北斗卫星导航系统的部署，北斗／GPS双系统单频RTK逐渐步入实用化阶段。本文基于5m超短基线与8km短基线的北斗和GPS实测数据，对北斗、GPS和北斗／GPS三种定位模式下的单频RTK模糊度解算成功率进行了对比分析。结果显示，北斗／GPS单频RTK模糊度解算成功率超过97％，可在短基线应用领域逐步推广。
With the deployment of BeiDou navigation satellite system, the application of single - frequency RTK positioning using dual system BeiDou/GPS is forthcoming. Based on the real data of 5m supershort baseline and 8kin short baseline, the success rate of single - fi＇equency ambiguity resolution using Beidou, GPS and BeiDou/GPS are comparatively analyzed. The results show that the single - frequency RTK using BeiDou/GPS, for which the success rate of ambiguity resolution is above 97% , may be popularised progressively in the short baseline application field.
