【摘要】 基于J₂轨道预测模型,设计了不同倾角和轨道高度圆轨道月球卫星,通过将J₂轨道预测模型预瞄准仿真结果与直接积分RKF7（8）法仿真结果相对比,研究了不同类型月球卫星轨道对-Y面卫星舱板激光通信终端瞄准精度的影响。仿真结果表明,J₂轨道预测模型可以满足月球极地卫星月地激光通信要求,当轨道高度为1 000 km和2 000 km的时候,10 min方位角偏差不超过40μrad,而俯仰角偏差仅为7μrad时,在一定程度上J2轨道预测模型可以满足月地激光通信预瞄准要求。更多还原

【Abstract】 Based on the J₂ orbit prediction model, lunar satellites with various inclinations and orbital heights have been designed. Then, by comparing the simulation results of the J₂ orbit prediction model with the direct integration RKF7（8）simulation results,pointing accuracy of lunar-ground laser communication is studied. The laser communication terminal is installed on the-Y plane satellite deck in our simulation. To a certain extent,the results show that the J₂ orbit prediction model can meet the requirements of lunar polar remote sensing satellites for lunar-ground laser communication. When the orbital height is 1 000 km and 2 000 km,the azimuth deviation of 10 min does not exceed 40 μrad,and the pitch angle deviation is only about 7 μrad. The orbit prediction model can satisfy the lunar-ground laser communication pointing requirements.更多还原
