To address the issues of limited nonlinear modeling capability and low prediction accuracy in single-model satellite clock bias prediction, a combined prediction model integrating long short-term memory (LSTM) neural network and random forest (RF) is proposed. This model fully leverages LSTM's ability to deeply mine the temporal characteristics of clock biases, while utilizing the ensemble learning mechanism of Random Forest to non-linearly compensate for the prediction residuals of LSTM, thereby achieving a significant improvement in prediction accuracy. Experiments demonstrate that, compared to the single LSTM model, the LSTM-RF combined model enhances the prediction accuracy for GPS, BDS, Galileo, and GLONASS satellites by 74.4% to 86.8%, 27.5% to 32.0%, 80.5% to 82.7%, and 0 to 18.2%, respectively, in short-term, medium-term, and long-term predictions. This verifies the feasibility and universality of the LSTM-RF combined model for predicting nonlinear clock bias sequences.

针对卫星钟差预报中单一模型非线性建模能力有限与预报精度不高的问题, 提出长短期记忆网络(LSTM)与随机森林(RF)的组合预报模型。该模型充分发挥LSTM对钟差时序特征的深度挖掘能力, 同时利用随机森林的集成学习机制对LSTM预测残差进行非线性补偿, 实现预报精度跃升。实验表明, LSTM-RF组合模型相比于单一LSTM模型, 在短、中及长期预报中GPS、BDS、Galileo及GLONASS卫星预报精度分别提升74.4%~86.8%、27.5%~32.0%、80.5%~82.7%及0~18.2%, 由此验证了LSTM-RF组合模型对于非线性钟差序列进行预报的可行性和普适性。
