摘要
上海天文台在利用全球激光测距资料估算ERP中引入了二级复弧法。本文详细介绍了估算ERP中的二级复弧法。该方法既提高了ERP的精度,又节省了计算机的CPU时间。在估算ERP中,二级复弧法使解得的ERP序列变化平滑;由于类阻力参数,光压系数与ERP一起求解,所以节省了解类阻力参数及光压系数的时间。复弧法是一个可以在卫星动力测地研究中推广的方法。上海天文台利用二级复弧法估算了地球自转参数序列ERP(SHA)87 L 01和EOP(SHA)88 L 01。
In this paper we introduce two-stage multiarc method in determining ERP from SLR and make a comparison between adopting this method or no. The advantages of adopting this method in determining ERP is obvious, not only it can improve the precise of determining ERP, but also it can greatly save the running-time of computer. This method has been used to determine earth rotation parameters series BRP (SHA) 87L01 and EOP (SHA) 88L01.
