摘　　要：由于各种误差的影响,民用传统单点定位精度只有数十米量级,为了提高其定位精度,采用局域差分GNSS定位技术,用户站接收来自基准站提供的坐标改正数,进行改正可以消除大部分误差,精度可以得到一定的提高。根据某GNSS网中1个点的观测数据来模拟用户站,其他3个点模拟基准站进行定位解算。研究结果表明,局域差分单点定位精度可以提高到亚米级,在矿区定位和测量中有重要作用。On account of the effects of various errors, the traditional single point positioning precision of civil can only achieve tens of meters. In order to improve the accuracy of positioning, use the local area difference GNSS positioning technique which the rover station receives the coordinate corrections and makes a comparison and correction to get a more accurate position.According to a point in GNSS network station observation data to simulate the user, the other three station observation data to simulate the base station, compile software for difference single point positioning solution. The experimental results show that the precision can be improved to the level of the decimeter and it plays an important role in the location measurement of mining area.
