摘要
随着我国北斗导航卫星系统(BDS)的不断发展和完善,基于GNSS多模系统的接收机种类不断增多,其RTK测量可实时获得高精度的定位信息,在国民经济和社会发展中具有广阔的应用前景。本文对多模GNSS接收机在空旷区域、大面积水域、树木下、高大建筑物旁、高压线下、雷达周围的RTK测量平面精度和固定解初始化时间进行研究,旨在探究不同特殊观测环境对RTK测量平面精度与初始化时间的影响,以期为特殊观测环境中高精度实时定位提供借鉴。
With the continuous development and improvement of China′s Beidou navigation satellite system （ BDS）, receiver typesbased on multi-mode GNSS system continue to increase, the RTK measurement can be real-time access to high precision positioninginformation, and it has a broad application prospect in national economy and social development. This paper study the RTK measurement plane accuracy and fixed solution initialization time of multi-mode GNSS receiver in different special observation environment,including open area, large area of water, trees under, tall buildings beside, under the high voltage line, around the radar, in order toexplore the different special observation environment influence on the plane precision of RTK and initialization time, so as to providereference for high precision real-time location in special observation environment.
