摘要
北斗卫星导航系统作为GNSS大家族中一颗冉冉升起的新星,它的加入使GNSS导航与定位技术更加多样化。针对超高层变形,文中结合国内某超高层变形监测实例,利用BDS/GPS/GLONASS/Galileo多系统组合RTK技术对其进行变形监测,并推导了多系统RTK定位模型,经研究发现,多系统组合下不仅增加了卫星可见数、改善了卫星空间分布结构,还使测量精度有了较大的提升,为今后观测环境价差下的高精度导航与定位提供了一种可靠的技术手段。
The Beidou satellite navigation system was a rising star in the GNSS family. It made GNSS navigation and positioning technology more diverse. In this paper,in view of the super high-rise deformation,it was carried out the deformation monitoring using the BDS/GPS/GLONASS/Galileo multi-system combined RTK technology combining with a super high-rise deformation monitoring example in China,and the multi-system RTK positioning model was deduced. Research found that the satellite visible number was increased,the spatial distribution structure of the satellite was improved,and the measurement accuracy had been greatly improved under multi-system combination,which provided a reliable technical means for the high-precision navigation and positioning under the observation of environmental price difference.
