摘要
手持式GPS具有捕捉卫星信号灵敏度高、定位速度非常快、使用方便等特点,目前已在工程领域低精度定位中得到广泛应用。但由于GPS默认所采用的相关参数一般与工程所采用的参数不一致,因此难以直接采用手持GPS观测的坐标值,为了准确测定坐标。必须对手持GPS相关参数进行准确配置,实现与工程坐标基准及尺度的统一。
The hand-hold GPS features high sensitivity of satellite signal capture, high positioning speed and convenient application, etc. Therefore, it is widely utilized in positioning with requirement of low precision in engineering field. But it is difficult to apply directly coordinates observed by the trend-hold GPS as relevant default parameters utilized by the hand-hold GPS is not in compliance with pa- rameters applied in engineering. To determine coordinates accurately, relevant parameters of the hand-hold GPS shall be configured accurately to realize unity of those with norms and codes of engineering coordinates.
