The invention provides a remote sensing micro-nano satellite system. The remote sensing micro-nano satellite system comprises a load, a platform, a star sensor, solar panels and a solar panel supporting structure, wherein the platform is mounted on the periphery of the load, the load comprises a camera and a force-bearing barrel, the force-bearing barrel is a cylinder with openings at the two ends, the camera is fixed inside the force-bearing barrel, the ground is subjected to observing and imaging through an opening at one end, and optical load data is generated; the platform is fixedly connected with the force-bearing barrel through an opening at the other end, a platform body is a cuboid with openings at two ends, one hole is formed in the side face of the cuboid, the hole is connectedwith one opening of the force-bearing barrel, multiple components are arranged on the platform body, and the multiple components are used for processing satellite platform information. The star sensoris used for the attitude sensitivity and measurement of a satellite on a rail and is used for acquiring the attitude data of the satellite, and is fixed on the outer side surface of the force-bearingcylinder, the solar panels are directly opposite to the bottom surface of the cuboid and are used for supplying electric energy to the remote sensing micro-nano satellite system, and the solar panelsupporting mechanism is used for supporting and connecting between the solar panels and the platform body.
