摘要
本文在单位矢量法测轨原理的基础上,给出了一种根据已知的部分粗略轨道根数进行约束求解的实用测轨方法。该方法已经在实际工作中得到应用。大量的实测计算表明,该方法在观测资料较差时,能够较好地提高初轨计算收敛率,测轨精度也优于一般比典的初轨计算方法。
According to the principle of Unit-Vector-Method,we present an initial orbit determination method with some restricted elements.This method has been put in practical use and the results show that even if the accuracy of data is not very good or the arc length not very long,this method is still efficient.The convergency is improved and the accuracy-also higher than those of classical methods.
