The invention discloses a remote-sensing
microsatellite. The remote-sensing
microsatellite comprises a stacked-type platform structure, a first body-mounted solar panel, a second body-mounted solar panel, a first expanded-type solar panel, a second expanded-type solar panel, a load camera, a load frame, a bottom plate, a battery array bracket, a
heat sink, an electronic cabin
heat sink, four antennas, four hinges and two heat knife brackets. According to the remote-sensing
microsatellite, the stacked-type platform structure is adopted, assembling is easy, and structural strength is high; all
layers of circuit boxes are mutually independent, and thus
electromagnetic interference is reduced; the load frame meets mounting of the effective load camera; the
mechanical strength of the whole
satellite main structure meets the requirement, a
satellite-
rocket separating device mounting connector is equipped, the implement space and a connector of a
thermal control device are simultaneously considered, and thus reliability and using flexibility are improved; and the problems that currently existing remote-sensing microsatellites cannot meet the capability of bearing the large camera load, the functional integration degree is low, the interchangeability of a
satellite platform is not strong enough, the production cost is high, and the production period is long are solved.
