摘　　要：在5G+新基建的移动互联网时代,高精度定位成为诸多领域的新宠,备受年轻一代的青睐。在此背景下,博盛尚科技向市场推出一种新型的RAC高精度卫星定位接收机,其特点是不使用任何差分技术(及惯导),仅采用普通民用单频信号(GPS L1或北斗B1),就能实现优于1米的定位精度。这项技术的应用,使高精度卫星定位既摆脱了对地基(星基)增强网的依赖,又大幅降低了成本,能够推动高精度卫星定位大规模普及应用时代的提前到来。In the mobile Internet era of 5 G+ new infrastructure,high-precision positioning has become a new favorite in many fields and is favored by the younger generation.In this context,BoshengShang Technology introduces a new RAC high-precision satellite positioning receiver to the market,which is characterized by the use of ordinary civil single-frequency signal(GPS L1 or Beidou B1) without any difference technology(and inertial navigation),and can achieve positioning accuracy better than1 meter.The application of this technology makes high-precision satellite positioning not only get rid of the dependence on the ground-based(satellite-based) enhanced network,but also greatly reduce the cost,which can promote the large-scale popularization and application of high-precision satellite positioning in advance.
