| 摘 要： | 起算点坐标的精度直接影响基线解算的精度，本文利用杭州湾大桥首级GPS控制网实测数据，通过比较人为增加起算点坐标误差后基线解算结果与实测结果，得出起算点坐标误差对基线解算是有影响的，起算点坐标任一分量的误差都会在基线的3个分量上引起误差。

| Abstract: | The precision of initial point's coordinate can affect the exactness of datum line directly.According to the characteristic of GPS project in the bridge of Hang Zhou bay,after we compared with anthropogenic increasing the error of the initial point can have the affect on the baseline solution,any error of initial point's coordinate may cause the error of three constituents of the baseline. |
