摘要
通过分析手持式GPS对三个不同点进行的观测结果与不同时间段对三个已知点的观测结果,以及单台仪器对两点间的距离测量与两台仪器同步观测两点求得的距离观测结果,提出改正手持式GPS的系统参数(DX、DY、DZ、DA、DF),消除系其统误差值,达到提高定位精度的目的,而且用两台仪器同步观测,可使结果更精确。
Through analyzed three different points and different time interval three known points observation results of hand-held GPS; distance measurement observation results between two points by single instrument and simultaneous observation by two instruments put forward hand-held GPS system parameters （DX, DY, DZ, DA and DF） correction to eliminate systematic error to achieve positioning precision. To use simultaneous observation by two instruments can make results more accurate.
