摘要：

The target landing site for Chang' e-1 mission is the rugged area of South Pole-Aitken(SPA) basin, which is located on the farside of the moon. There arc many craters densely distributed in the SPA basin, the uneven topography will result in high risk of sunlight and communication shield when the lander works on lunar surface. Communication and sunlight shield was analyzed. Then, the solution to reduce the lander's survival risk generated by the shielding was presented in three aspects: to increase the landing precision by optimizing the trajectory control strategy, to optimize the lunar surface operating programme, as well as to add the function of the lander' s autonomus management. The solution has been used in the Chang ' e-1 probe successfully, providing reference for future deep space exploration missions.
