The invention relates to an SPORT (Solar
Polar Orbit Radio Telescope)
clock scanning
satellite comprising a
satellite body, a subsatellite, a stretching arm, a
solar cell paddle, a butt-joint ring, a geosynchronous communication antenna and an
orbit control engine. The SPORT
clock scanning
satellite is characterized in that the satellite body is in a cuboid shape and has a three-cabin internal structure; and the subsatellite concretely comprises a subsatellite body, a
helical antenna, a reflecting plate, a reflecting plate support frame, a flexible solar
paddle, a
helical antenna unfolding guide mechanism, a guide unfolding
drive motor, a speed
reducer, an
S wave-band digital antenna, a
receiver and a
power module. The SPORT
clock scanning satellite adopts a main force-bearing structure which is a
central force-bearing drum and a radial partition board force-transferring path, has a clear and concise force-transferring link, and is beneficial to the design of structure strength and rigidity through configuration distribution; the SPORT clock scanning satellite is provided with an
orbit maneuver motor so as to transfer orbits per se when flying during a
cruise phase, thereby reducing the requirements on a carrying upper stage; in addition, the SPORT clock scanning satellite ensures the stability of a better satellite attitude through the distribution position of a propelling module of the satellite body.
