| 摘 要： | 随着多个GNSS系统不断建成,天空中的导航卫星越来越多,使得RTK作业时的观测量也越来越多,这对提高单频单历元RTK的可靠性起到了至关重要的作用。本文分析了GLONASS信号频分多址的特点,对GPS/GLONASS/BDS单历元单频RTK定位的算法和模型进行了研究,提出了一种适用于三系统组合条件下短基线单频单历元RTK定位的算法,并采用实测数据对算法进行了验证,结果表明,GPS/GLONASS/BDS单历元单频RTK定位是可行的。

| Abstract: | As the Global Navigation Satellite System ( GNSS) began to enter into the age with more systems, the increasing number of navigation satellite visible in the sky, brings the benefits to ambiguity resolution.Finally, the accuracy and reliability of GNSS single-epoch and single -frequency RTK positioning is greatly improved.Considering the characteristics of GLONASS signal with frequen-cy division multiple access, the model of single-epoch and single-frequency the RTK positioning of GPS/GLONASS/BDS is stud-ied in this paper, then the feasibility of the model was verified with the measured data , and the result shows that single-epoch and single-frequency RTK positioning of GPS/GLONASS/BDS is feasible. |
