摘　　要：在GPS信号弱或无信号的特殊区域内,利用GPS在特殊区域边缘地带建立基站。通过基站和流动站与卫星之间的数据传递,完成特殊区域外部的点位采集,利用微波测距原理采用空间后方交会法,计算出坐标向量,利用已知点坐标推算出点位具体坐标。In the special area where GPS signal is weak or no signal, the base station is built by using GPS at the edge of the special area. Through data transmission between base station and mobile station and satellite, point position acquisition outside special area is completed. Using the principle of microwave ranging and space rear intersection method, coordinate vectors are calculated, and specific coordinates of point position are calculated by known point coordinates.
