面向微纳遥感星座构建的阻力差分控制方法OA北大核心CSTPCD

Considering weight,power consumption,volume and cost of the whole satellite,some micro-nano satellites are usually not equipped with propulsion systems.In order to meet the con-stellation establishment requirements,the differential drag control(no-propulsion control)tech-nology method is proposed.By adjusting the windward area of the solar array,the differential drag is used to increase or decrease the difference of orbital semi-major axis between two satel-lites.Then,phase of the micro-nano remote sensing satellite constellation can be controlled with-out changing the satellites'body attitude or affecting the application of the payload.The differential drag control method is verified by using 20 micro-nano remote sensing satellites to construct a con-stellation.By applying the differential drag control technology to the phase control of micro-nano remote sensing satellite constellation,the satellites can be equally phased in the same orbital plane,and the constellation construction can be successfully realized.
