| 摘 要： | 目前对IGS站快速精密星历和最终精密星历研究的比较多,而对预报精密星历的研究还比较少。本文采用预报精密星历和钟差对机载GPS实测数据进行解算分析,发现其定位结果比广播星历求的导航结果精度高至少一个数量级。因为预报精密星历和钟差可以提前获得,在一些时效性较高的场合很有价值。

| Abstract: | Currently,the research of IGS rapid precise ephemeris and the final precision ephemeris are more,but the research on the prediction precision ephemeris still less.This paper solves and analyzes the airborne GPS measured data using the forecasting precision ephemeris and clock error.It found that the precision of this positioning results was higher than using broadcast ephemeris at least an order of magnitude.Because the forecast precise ephemeris and clock errors can access earlier,this is valuable in some high timeliness places. |
