Sun inertia pointing master-slave non-contact dual-super satellite platform

Abstract

The invention provides a sun inertia pointing master-slave non-contact dual-super satellite platform comprising a load cabin. The load cabin comprises a first side plate, a partition plate, a first top plate, a first bottom plate, a solar cell, an effective load data transmission antenna, a data processing unit and a relative position sensor. The first top plate is a sun observation load datum plate; the first bottom plate is a magnetic suspension direct force control mechanism mounting angle plate; a sun observation load is mounted on the sun observation load datum plate; a magnetic suspension direct force control mechanism and a part of the structure of a two-cabin locking and unlocking mechanism are mounted on the magnetic suspension direct force control mechanism mounting angle plate;the relative position sensor is mounted on the magnetic suspension direct force control mechanism; and the load cabin is connected to the upper portion of a platform cabin in a butting mode. The requirements for the sun observation load with ultrahigh pointing precision and ultrahigh attitude stability can be met.

Description

technical field [0001] The invention relates to a satellite platform, in particular to a master-slave non-contact dual supersatellite platform with inertial orientation to the sun. Background technique [0002] A sun observation satellite with ultra-high pointing accuracy and ultra-high stability is under development. The weight of the whole star is about 250kg, and its sun observation load weighs about 35kg. The load envelope is 650mm×550mm×250mm, and the pointing accuracy requirement is 5×10-4 degrees, attitude stability is 5×10-6 degrees / second. [0003] Most of the existing solar observation satellite platforms are designed with a fixed connection between the payload and the satellite platform, which cannot fully isolate the disturbance of the satellite platform. [0004] Therefore, in order to meet the requirements of ultra-high pointing accuracy and ultra-high stability indicators of satellite solar observation payloads, including improving the payload space environme...
