【摘要】 目前大多数Android智能移动终端主要使用单点定位技术,它的定位误差大约在7m左右或者更大。该项目基于An-droid 7.0及以上系统平台,在智能移动终端设计专用的高精度实时动态定位软件GNSSRTK GDUT,该软件基于智能移动终端内置的廉价GNSS导航芯片API输出的原始测量值,配合差分参考基站和差分服务器获取的参考基站测量的原始信息,在智能移动终端进行双差方法修正误差,进行高精度实时动态定位解算,从而达到2m以内的定位精度。更多还原

【Abstract】 Currently, most Android smart mobile terminals use single-point positioning technology, and its positioning accuracy isabout 7 m or even worse. Based on the Android 7.0 or above system platform, this system designs a dedicated high-performance po-sitioning solution software GNSSRTK GDUT for the intelligent mobile terminal. Based on output by the inexpensive built-in GNSSnavigation chip API of the raw measurement values, the software corrects the error in the intelligent mobile terminal by combiningthe original information of the differential correction of the GNSS reference station obtained by the differential server to perform re-al-time kinematic high-precision solution, so as to achieve a positioning accuracy of 2 meter or better.更多还原
