快速精密星历与最终精密星历对定位精度的影响和比较

Influence and Comparison of Rapid Precise Ephemeris and Final Precise Ephemeris on Positioning Precision

星历的精度会对单点定位和相对定位的解算结果产生影响,利用IGS跟踪站给出的观测数据以及快速精密星历和最终精密星历来进行计算,结果表明,用快速精密星历代替最终精密星历是可行的。

The impact of ephemeris on single point positioning and in this paper,sequently cise ephemeris respectiv calculates ely the feasibility that IGS rapi using d eph and analyzes an example for the rapid observed data offered by IGS tracking relative positioning is introduced precise ephemeris and final pre- stations. The conclusion shows emeris can commonly replace the final ephemeris.
