摘要
用实例数据验证了GPS PPP技术的精度水平及影响因素等。结果表明,PPP技术的精度水平可以用于小比例尺测图直接定向;PPP精度受限于精密星历的精度水平及软件的算法。
This paper demonstrates the factors which influence the GPS PPP accuracy and selects a large number of data to get the PPP accuracy level. The results show that the level of accuracy of the PPP technology can be used to direct orientation of small - scale map- ping and the PPP accuracy is limited by the precise ephemeris accuracy level and software algorithms.
