摘　　要：本文提出了基于Bayes推理数据融合理论的卫星轨道控制效果快速评估方法。首先计算卫星遥测数据中温度、姿态、轨道数据信息量的先验概率,然后通过Bayes推理方法进行数据融合,得到后验概率,根据后验概率对轨控效果进行判定。结果表明,通过融合算法计算轨控概率,相比通过单一信息量计算更加准确、可靠。A data fusion method based on Bayes reasoning is proposed to promptly judge the orbit control effect of satellite. Firstly, the prior probability of satellite telemetry data including temperature, attitude, and orbit is calculated. Then, the posterior probability is obtained by data fusion using Bayes reasoning method, and the orbital control effect is judged according to the posterior proba-bility. The results show that it is more accurate and reliable to calculate the orbit control proba-bility by data fusion algorithm than by using a single amount of information.
