| 摘 要： | 星历误差和星钟误差是GPS动态精密单点定位的主要误差源，不同的星历和钟差产品会对结果产生影响。利用IGS网站给出的不同星历和钟差数据及广播星历数据进行计算，采用Waypoint软件进行不同的组合计算，对不同星历和钟差组合对机载GPS数据定位结果进行分析。 |
| 关 键 词： | 精密星历 精密钟差 车载GPS 动态精密单点定位 |

| Abstract: | Ephemeris error and clock error are the main source errors of GPS kinematics precise point posi- tioning. Different ephemeris and clock difference will affect the results. The paper using the different e- phemeris and clock difference from IGS website to calculate, using Waypoint software to carry on different combination calculation with Car GPS data, and analyzing the position results, has obtained some useful conclusion. |
| Keywords: | precise ephemeris precise clock error car GPS kinematics precise point positioning |
