Auxiliary system for mounting optical camera in deep-embedded mode

Abstract

The invention discloses an auxiliary system for mounting an optical camera in a deep-embedded mode. The auxiliary system comprises two parts of a mechanical guiding device and a real-time monitoring system which are arranged inside a cabin body of a load cabin. The mechanical guiding device is in fastened connection with the load cabin through a load cabin hole position and guides the camera to beslowly embedded in the cabin body of the load cabin through a guiding roller set. The real-time monitoring system comprises a position and pose positioning part and a position and pose monitoring part for monitoring the safe distance between the camera and a satellite body by 360 degrees. Through an active and passive combination mounting process, the operation intensity of manual holding and gapobserving difficulty can be lowered, mounting risks are reduced, and the mounting time is saved.

Description

technical field [0001] The invention belongs to the technical field of spacecraft ground support equipment, and in particular relates to an auxiliary system for highly reliable installation of spacecraft optical payloads. Background technique [0002] The optical camera is an important payload of a remote sensing satellite. Due to the heavy weight of the camera (usually 500kg to 2000kg), in order to reduce the height of the center of mass of the entire satellite, the optical camera is often embedded in the interior of the payload cabin with a large depth. For example, see figure 1 , figure 1 It is a schematic diagram of the installation state of the camera embedded in the payload cabin in the prior art; due to the limitations of the satellite configuration and other aspects, the distance between the camera and the star is small, which brings great difficulty to the installation and disassembly of the camera. The installation of the optical camera needs to be carried out in ...

Problems solved by technology

[0002] The optical camera is an important payload of a remote sensing satellite. Due to the heavy weight of the camera (usually 500kg to 2000kg), in order to reduce the height of the center of mass of the entire satellite, the optical camera is often embedded in the interior of the payload cabin with a large depth. For example, see figure 1 , figure 1 It is a schematic diagram of the installation state of the camera embedded in the load compartment in the prior art; due to the limitations of the satellite configuration and other aspects, the distance between the camera and the star is small, which brings greater difficulty to the installation and removal of the camera

The installation of the optical camera needs to be carried out in the form of hoisting. At present, the minimum distance between some models of cameras and the load cabin is only 5mm. The installation risk is high, and accidents such as bumping and extrusion are prone to occur during the installation process. There are many optical sensitive components in the optical camera, and accidents such as bumping and extrusion have a great impact on the quality of the camera.
