摘要
在实时动态(Real Time Kinematic,RTK)作业模式下,GPS基准站应布设在无遮挡覆盖的开阔区域,以使其对卫星有最佳的可见性,保证基准站为流动站提供更为精确的实时差分信息。介绍了RTK作业模式,阐述了通视分析在GPS基准站布设中的重要性,对在有限范围空间数据支持下卫星可见性分析方法进行了重点研究,基于MGIS软件平台对该方法的具体应用进行了实验,并对实验结果进行了展示,说明了通视分析在卫星可见性分析计算中的重要性和可行性。
In the RTK operation mode,the GPS reference station should be laid in the open unobstructed area to make the satellite visibility best to provide more accurate real-time differential information for the rover station.This paper firstly introduces the RTK mode of operation and describes the importance of the visibility analysis in the layout of the GPS reference station.Then the analysis method of satellite visibility supported by limited spatial data is discussed.Finally some experiments about the application of that method are done on MGIS,and the experiment results are presented in this paper,which prove the importance and feasibility of the visibility analysis in the satellite visibility calculation.
