摘要 GLONASS卫星位置解算是多系统兼容卫星导航接收机组合定位解算中一项重要的内容,对算法的稳定性、精度和计算量有较高的要求。引入了一种求解GLONASS导航卫星位置的新方法———基于Adams预测校正公式的GLONASS卫星轨道积分方法。应用实际数据对此算法和四阶龙格—库塔算法进行了对比验证,结果表明此方法是一种求解GLONASS卫星位置的有效方法,其稳定度优于四阶龙格—库塔方法,且计算量小。 Calculation of GLONASS satellite position is an important part of multiple systems combined positioning algorithm of the GNSS receiver,which has more demands on algorithm's stability,accuracy and computational cost.A new GLONASS orbit integral algorithm based on Adams forecasting-correcting formula is introduced in this paper.This paper has verified the algorithm with practical data and compared it with the Fourth-Order Runge-Kutta method.The results show that the new algorithm is an effective method to calculate GLONASS satellite position.It is obvious that the stability of the proposed method is superior to the Fourth-Order Runge-Kutta method and the computational cost is low.
