  • Tianwen-1 is China's first independent interplanetary mission. It will complete orbiting, landing, and roving tasks in one operation. Exploiting tracking data from gathered during this extended mission, this paper explores possible ways to improve the Mars gravity field model through simulations. We designed two types of orbits, a polar and a near equatorial large eccentricity orbit and recovered six gravity solutions considering various error sources. By the power spectrum of these gravity models was analyzed and evaluated, finding that a month of tracking data from the polar orbit or the combined polar and near equatorial orbit could be used to properly reconstruct the Mars gravity field model with orders and degrees of 42 under the 0.1 mm/s measurement noise. The results show that after considering the influence of comprehensive error, the accuracy of gravity field solutions from the two types of orbits was similar. Nevertheless, the orbit with large eccentricity near the equator has a slightly stronger constraint on more than 35 order and degree coefficients.
