内编队飞行系统（IFFS）由一颗外层卫星和一颗在屏蔽腔内自由飞行的实心球形验证质量的内层卫星组成，可以构成一个纯重力轨道，实现对地球重力场的精确测量。外卫星对内卫星的引力是对纯引力轨道的一个重要扰动源，需要限制在10 − 11 ms − 2量级。然而，引力扰动力实际上是10 − 9 ms − 2量级，必须通过专门的补偿质量块来减小。内卫星相对于其标称位置的相对运动区域的尺寸在1cm以内，这增加了补偿块设计的复杂性。为了保证补偿后相对运动区域内的引力满足要求，提出了基于减小内星标称位置处引力的补偿块迭代设计策略。根据IFFS的现状设计了补偿模块，在最小附加质量的情况下，将该区域的引力扰动力降到10 − 11ms − 2量级。
The Inner Formation Flying System (IFFS) consisting of an outer satellite and an inner satellite which is a solid sphere proof mass freely flying in the shield cavity can construct a pure gravity orbit to precisely measure the earth gravity field. The gravitational attraction on the inner satellite due to the outer satellite is a significant disturbance source to the pure gravity orbit and is required to be limited to 10−11ms−2order. However, the gravitational disturbance force was on 10−9ms−2order actually and must be reduced by dedicated compensation mass blocks. The region of relative motion of the inner satellite about its nominal position is within 1cm in dimension, which raises the complexity of the compensation blocks design. The iterative design strategy of the compensation blocks based on reducing the gravitational attraction at the nominal position of the inner satellite is presented, aiming to guarantee the gravitational force in the relative motion region within requirements after the compensation. The compensation blocks are designed according to the current status of IFFS, and the gravitational disturbance force in the region is reduced to 10−11ms−2order with minimized adding mass.
