摘要 从某颗在轨卫星地面轨迹漂移“异常”出发,分析了该现象发生的内在机理,建立了零偏模式下(卫星姿态偏航角保持为零)光压摄动力沿迹方向累积效应解析模型,并基于历史观测数据通过轨道改进估计模型参数。最后,利用该卫星2018年真实地面轨迹对新模型预报精度进行验证。结果表明,采用新模型后,卫星地面轨迹漂移预报误差得到明显改善,为该卫星轨迹保持控制策略制定提供了技术支持。

Abstract: The intrinsic "anomaly"  mechanism of the ground track drift of a satellite in orbit is analyzed and the model of solar radiation pressure accumulation effect in alongtrack direction in zero yaw attitude mode(keeping yaw angle zero in one orbit cycle) is built. Then, the model parameters are estimated using historical observation data through POD. Finally, the accuracy of the new model is verified by using the real ground track of the satellite in 2018. The results show that the accuracy of satellite ground track drift forecast is significantly improved by using the new model. It can provide technical support for developing the control strategy of ground track keeping for this kind of satellite.
