摘　　要：提出一种基于交互式迭代和批量最小二乘法的在轨质量特性计算方法,仅使用陀螺作为敏感器,动力学模型适用于零动量和偏置动量两种控制模式,考虑了卫星与飞轮动量交换以及参数之间耦合关系,且能够适用于在轨不进行连续大角度姿态机动的卫星。计算结果表明,此方法具有快速、稳定的收敛特性和较高的计算精度。This paper brings forward the method based on interactive iteration and batch least square, in which only gyro is used without any other sensor. The model of the method adapts to both zero-momentum system and bias momentum system, considering momentum exchange be- tween the satellite and the momentum wheels as well as the coupling among the parameters. The method is also effective for the high orbit satellites which do not maneuver with large attitude an- gle. The results realize that this method converges rapidly, stably and accurately.
