摘要
公路勘测GPS测量常采样静态相对定位技术,需要至少一双公共点,提出采用连续运行基准站方法,使未知点与基准站组成远距离同步观测,此方法用于北京和东北地区公路勘测工程中,结果表明连续运行基准站的测量方法在与常规测量方法相同测量精度的结果下,提高了作业效率。
Highway Survey and regular sampling of static GPS measurements relative positioning technology,required at least one pair of public point,given the continuous operation of the base station means by which the unknown point and the base stations synchronize remote observation,this method has been applied to Beijing and Northeast Highway Survey and Engineering,the results show that the continuous operation of base station measurements and conventional measurements in the same method as the measurement accuracy of the measurement results, the improved operational efficiency.
