The invention discloses a single-satellite high-precision collaborative remote sensing method, which is applied to a multi-load satellite platform, and is characterized in that an effective load is connected with the satellite platform through a flexible cable and a non-contact actuator to form a multi-loop control system; the method comprises the following steps: (1) enabling the flexible cable to be equivalent to a combination of a plurality of beads, springs and dampers; (2) establishing acting force equations and moment equations of all the effective loads, all the flexible cables and the satellite platform; establishing a control equation and constraint conditions of the multi-loop control system; and (3) according to a control equation and constraint conditions of the multi-loop control system, orientation is performed on the payloads, the multiple payloads point to the same target, and the distance between the payloads and the satellite platform is controlled within a critical distance. According to the method, the non-contact actuator and the flexible cable are adopted for dynamic modeling, and a control equation of a multi-loop control system is established, so that super-static and super-stable and cooperative work of a plurality of effective loads is realized on a single satellite platform.
