摘要:
为了评估北斗三频观测值在短基线RTK应用中的定位性能,采用Kalman滤波模型进行动态环境下北斗三频模糊度固定,经实测数据验证,动态环境下北斗三频RTK只需1个历元即可得到固定解,模糊度成功率较GPS双频和BDS双频分别提高了15.0%和14.1%,验证了我国北斗三频信号在短基线RTK定位中的优越性能。

Abstract:
To assess the positioning performance of BeiDou triple-frequency observations in short baseline RTK applications, the Kalman filter model is proposed to fix the ambiguity of triple-frequency observations in dynamic environments. The results show that the fixed solution can be obtained by single epoch, and the ambiguity reliability is improved by 15.0% and 14.1% compared with that the GPS and BDS dual-frequency observations.
Key words:  Triple-frequency  Dynamic  RTK  Kalman filter
