at launch, fengyun 2-07 had a mass of , however by the time it reaches its operational orbit, this will have decreased to , partly through jettisoning the fg-36. the spacecraft is cylindrical, with a diameter of , and a length of fully deployed. it is spin-stabilised at a rate of 100 rpm, and carries a five-channel stretched visible and infrared spin scan radiometer, or s-vissr, capable of producing visible light and infrared images of the earth. the s-vissr will return visible-light images with a resolution of , and infrared images with a resolution of . it will produce a full-disc image every thirty minutes, as well as imaging smaller areas of interest. in addition to s-vissr, fengyun 2-07 also carries an x-ray detector to monitor the sun, and detect solar flares.
