Magnetic levitation control on-orbit test method for separated micro satellite

Abstract

The invention provides a magnetic levitation control on-orbit test method for a separated micro satellite. The method comprises the steps of adopting a magnetic levitation control experiment to verifythe magnetic levitation control, separately testing the separated micro satellite under different on-orbit working states, wherein an attitude orientation mode is to power off an inter-cabin connection unlocking device, power on an on-board sensor and a magnetic levitation mechanism, power off the on-board sensor and the magnetic levitation mechanism after verification and power on the inter-cabin connection unlocking device, and an attitude maneuvering mode is to power on and lock the inter-cabin connection unlocking device, enable the satellite cabins to be in a connected state, enable thesatellite to enter an attitude maneuvering process, power off the inter-cabin connection unlocking device, start the on-board sensor and the magnetic levitation mechanism to work, power off the on-board sensor and the magnetic levitation mechanism after verification and power on the inter-cabin connection unlocking device. The method can cover all attitude modes when the satellite is in an orbit,fully assesses the performance of magnetic levitation control when the satellite is in the orbit, is simple and reliable, and has a good engineering application value.

Description

technical field [0001] The invention relates to a satellite on-orbit test method, in particular to an on-orbit test method for a maglev control of a separate tiny satellite. Background technique [0002] Remote sensing satellite is a mission-oriented earth observation satellite, which can realize continuous observation of global key military areas, disaster occurrence areas, scientific research areas, etc. Perform long-term, fast-access imaging. Remote sensing satellites have high requirements for pointing accuracy and stability. [0003] In order to ensure the stability of existing satellite platforms, vibration suppression and isolation are required. The separated micro-satellite uses maglev control technology to isolate the platform cabin from the load cabin, and isolates the vibration source of the platform cabin. The pointing accuracy and stability of the load cabin are higher than those of traditional satellites, which can meet the requirements of remote sensing, sur...
