| 摘 要： | 研究GPS导航星座精密轨道确定的基本问题及其处理策略.基于2008年3月29日至4月7日的148个站的IGS站数据,计算了GPS卫星轨道的单天解和3天解,通过与CODE中心的最终轨道进行比较,评价了相应轨道的精度.结果显示,基于该导航星座轨道生成策略,单天轨道解径向精度优于9 cm,3天解轨道径向精度优于5 cm.

| Abstract: | The basic problem and the processing strategy about precise orbit determination of GPS navigation constellation were studied.From the observations of 148 IGS stations from March 29 to April 07 in 2008,one-day and three-day orbit solutions of GPS navigation constellation were determined.In order to evaluate the accuracy of the orbit,the orbit was compared with final orbit products produced by CODE.The results show that using this strategy,the one-day orbit solutions accuracy is better than 6cm in radical dir... |
