| 摘 要： | 本文介绍了基于国际探月观测数据建立的月球重力场模型:8×4、15×8、13×13、5×5、7×7、16×16-1/2/3、Lun60d、GLGM-1/2、LP75D/G、LP100K/J、LP165P、LP150Q和SGM90d;通过对比SST-HL/LL-Doppler-VLBI和SST-HL/SGG-Doppler-VLBI跟踪观测模式的优缺点,建议我国将来首期月球卫星重力测量计划采用SST-HL/SGG-Doppler-VLBI较优;其次,通过对比静电悬浮、超导和量子卫星重力梯度仪的优缺点,建议我国将来首期月球卫星重力梯度计划采用静电悬浮重力梯度仪;并建议我国将来首颗月球重力梯度卫星的轨道高度(50～100 km)选择在已有月球探测卫星的测量盲区,轨道倾角(90°±3°)设计为有利于月球卫星观测数据全球覆盖的近极轨模式。 |

| Abstract: | In the paper,firstly,the lunar gravitational field models produced by observations of lunar exploration including 8×4,15×8,13×13,5×5,7×7,16×16-1/2/3,Lun60d,GLGM-1/2,LP75D/G,LP100K/J,LP165P,LP150Q and SGM90d were expatiated;secondly,SST-HL/SGG-Doppler-VLBI tracking mode was suggested in the future first-stage lunar satellite gravity measurement in China by a comparison of strongpoints and shortcomings between SST-HL/LL-Doppler-VLBI and SST-HL/SGG-Doppler-VLBI modes;thirdly,the electrostatic suspension gravity gradiometer was a preferable selection in the future first-stage lunar satellite gravity gradiometry mission in China by a comparison of advantages and disadvantages among electrostatic suspension,superconducting and quantum gravity gradiometers.Finally,the orbital altitude(50~100 km) of lunar gravity gradiometry satellite was selected in the unmeasurable area of existing lunar satellites and orbital inclination(90°±3°) was designed as the near-polar-orbit model for global coverage of lunar satellite observations in China. |
