Abstract：The implemented international Martian exploration programs including “Mars, Zond and Phobos1/2” in USSR, “Mariner, Viking, Mars Observer, Mars Global Surveyor, Mars Pathfinder, Mars Climate Orbiter, Mars Polar Lander, Mars Odyssey, Spirit, Opportunity, Mars Reconnaissance Orbiter and Phoenix” in USA, “Mars96” in Russia, “Hope” in Japan and “Mars Express” in Europe, and the future domestic and overseas Martian measurement missions are presented. The Martian gravitational field models produced by Martian observations are introduced amply,which including.1) the U.S.: 6×4, 6×6, 10×10, Mars50c, MGS75B, MGS75D/E, MGS85F/F2/H2, MGS95I/J, GMM1, GMM2B, GGM1025 and GGM1041C.2) the U.K.: 6×6.3) France: 18×18 and MGGM08A. The measuring principle and advantages in the SGGDopplerVLBI tracking mode are described,which will be applied in the future firststage China’s Martian satellite gravity measurement. It is concluded that the electrostatic suspension gravity gradiometer is preferable in the future firststage Martian satellite gravity gradiometry mission in China by a comparison of strongpoints and shortcomings from electrostatic suspension, superconducting and quantum gravity gradiometers.
