| 1 | Lunar topographic model CLTM-s01 from Chang’E-1 laser altimeter显示文摘More than 3 million range measurements from the Chang’E-1 Laser Altimeter have been used to produce a global topographic model of the Moon with improved accuracy. Our topographic model, a 360th degree and order spherical harmonic expansion of the lunar radii, is designated as Chang’E-1 Lunar Topography Model s01 (CLTM-s01). This topographic field, referenced to a mean radius of 1738 km, has an absolute vertical accuracy of approximately 31 m and a spatial resolution of 0.25o (~7.5 km). This new lunar topographic model has greatly improved previous models in spatial coverage, accuracy and spatial resolution, and also shows the polar regions with the altimeter results for the first time. From CLTM-s01, the mean, equatorial, and polar radii of the Moon are 1737103, 1737646, and 1735843 m, respectively. In the lunar-fixed coordinate system, this model shows a COM/COF offset to be (-1.777, -0.730, 0.237) km along the x, y, and z directions, respectively. All the basic lunar shape parameters derived from CLTM-s01 are in agreement with the results of Clementine GLTM2, but CLTM-s01 offers higher accuracy and reliability due to its better global samplings. | PING JinSong HUANG Qian YAN JianGuo CAO JianFeng TANG GeShi SHU Rong | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，7： | 19 |
| 2 | Pre-LOI trajectory maneuvers of the CHANG'E-2 libration point mission显示文摘This paper addresses pre-LOI (before Lissajous orbit insertion) trajectory maneuvers for the libration point mission of CHANG'E-2,which is the first Chinese satellite to fly to the Sun-Earth L2 libration point and the first satellite ever to fly to the L2 point from lunar orbit.First,a transfer trajectory for the mission is designed based on InterPlanetary Superhighway theory under the constraint of the remaining propellant,TT&C (telemetry,track and command) and sunlight conditions.The effects of trajectory maneuver errors on the mission are also analyzed.Second,based on the analysis results,the article investigates the trajectory maneuver schemes for the lunar escape and transfer trajectory maneuvers employing mathematical models and operational strategies.The mission status based on our maneuver schemes is then presented,and the results of control operation and corresponding analysis are provided in detail.Finally,the future trajectory maneuver in the Lissajous orbit is discussed.According to the analysis of the CHANG'E-2 TT&C data,the trajectory maneuver schemes proposed in the article work properly and efficiently. | WU WeiRen LIU Yong LIU Lei ZHOU JianLiang TANG GeShi CHEN YongZhi | 2012 | Science China(Information Sciences)2012，55，6： | 12 |
| 3 | New features of the Moon revealed and identified by CLTM-s01显示文摘Previous analyses showed a clear asymmetry in the topography,geological material distribution,and crustal thickness between the nearside and farside of the Moon. Lunar detecting data,such as topography and gravity,have made it possible to interpret this hemisphere dichotomy. The high-resolution lunar topographic model CLTM-s01 has revealed that there still exist four unknown features,namely,quasi-impact basin Sternfeld-Lewis (20°S,232°E),confirmed impact basin Fitzgerald-Jackson (25°N,191°E),crater Wugang (13°N,189°E) and volcanic deposited highland Yutu (14°N,308°E). Furthermore,we analyzed and identified about eleven large-scale impact basins that have been proposed since 1994,and classified them according to their circular characteristics. | HUANG Qian PING JinSong SU XiaoLi SHU Rong TANG GeShi | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，12： | 7 |
| 4 | Chang’E-1 orbiter discovers a lunar nearside volcano: YUTU Mountain显示文摘In the day time of the Moon surface, the strong illumination from high altitude and high albedo rate radical craters will introduce the illumination effect on observing the nearby low altitude, low albedo rate and shallow small slop rate area seriously, and even can 'hide' the later area from the light. Based on the lunar global topography model obtained by Chang’E-1 mission, and by comparing with the lunar gravity model, a volcano named 'YUTU Mountain' has been identified. It is a volcano with diameter of ~300 km and height of ~2 km located at (14°N, 308°E) in Oceanus Procellarum. Besides, the DEM of another volcano named 'GUISHU Mountain' in the same area has been improved. This new discovery will benefit the study of lunar magmatism and volcanism evolution in the nearside of the Moon. | PING JinSong HUANG Qian SU XiaoLi TANG GeShi SHU Rong XIAO Long HUANG Jun | 2009 | Chinese Science Bulletin2009，54，23： | 4 |
| 5 | A digital open-loop Doppler processing prototype for deep-space navigation显示文摘A prototype based on digital radio technology with associated open-loop Doppler signal processing techniques has been developed to measure a spacecraft's line-of-sight velocity. The prototype was tested in China's Chang'E-1 lunar mission relying on S-band telemetry signals transmitted by the sat-ellite,with results showing that the residuals had a RMS value of ~3 mm/s (1σ ) using 1-sec integration,which is consistent with the Chinese conventional USB (Unified S-Band) tracking system. Such preci-sion is mainly limited by the short-term stability of the atomic (e.g. rubidium) clock at the uplink ground station. It can also be improved with proper calibration to remove some effects of the transmission media (such as solar plasma,troposphere and ionosphere),and a longer integration time (e.g. down to 0.56 mm/s at 34 seconds) allowed by the spacecraft dynamics. The tracking accuracy can also be in-creased with differential methods that may effectively remove most of the long-term drifts and some of the short-term uncertainties of the uplink atomic clock,thereby further reducing the residuals to the 1 mm/s level. Our experimental tracking data have been used in orbit determination for Chang'E-1,while other applications (such as the upcoming YH-1 Mars orbiter) based on open-loop Doppler tracking will be initiated in the future. Successful application of the prototype to the Chang'E-1 mission in 2008 is believed to have great significance for China's future deep space exploration. | JIAN NianChuan SHANG Kun ZHANG SuJun WANG MingYuan SHI Xian PING JingSong YAN JianGuo TANG GeShi LIU JunZe QIU Shi FUNG Lai-Wo ZHANG Hua WANG Zhen GOU Wei | 2009 | Science China(Physics,Mechanics & Astronomy)2009，52，12： | 2 |
