A method for adjusting the installation accuracy of satellite remote sensing instruments based on drilling templates

Abstract

The invention provides a satellite remote sensing instrument installing precision adjusting method based on a drill plate. The method comprises the following steps that the drill plate and a vibrationisolation device are installed on a satellite and subjected to installing precision adjusting; the vibration isolation device and the drilling plate as well as the vibration isolation device and thesatellite structure are subjected to pin hole match working; the drilling plate and the vibration isolation device are disassembled from the satellite; the drill plate is subjected to installing precision resetting in the state of being not installed on the satellite; a remote sensing instrument detecting main body and the vibration isolation device are assembled and subjected to installing precision adjusting; the remote sensing instrument detecting main body and the vibration isolation device are subjected to pin hole match working; and the remote sensing instrument detecting main body and the vibration isolation device are installed on the satellite, and the final installation precision is measured. According to the satellite remote sensing instrument installing precision adjusting method based on the drill plate, on the premise that the installation precision of the remote sensing instrument detecting main body is ensured, the remote sensing instrument detecting main body development procedure and the satellite structure development procedure are independent from each other, meanwhile, by adopting the mode that the drill plate is subjected to pin hole match working, the effectthat installation precision data are effectively transmitted between the remote sensing instrument detecting main body and the satellite structure is achieved, and the method has the advantages that the method is simple, and the implementation cost is low.

Description

technical field [0001] The invention relates to the technical field of satellite overall design, in particular to a method for adjusting the installation accuracy of a satellite remote sensing instrument based on a drilling template. Background technique [0002] With the wide application of satellites in weather forecasting, resource detection, ocean observation, disaster reduction, etc., users have put forward higher and higher requirements for the resolution of remote sensing instruments carried by satellites. If the installation accuracy of the remote sensing instrument cannot be guaranteed, its optical axis cannot be precisely pointed to the target area, and high-resolution images cannot be obtained. In order to ensure the normal operation of remote sensing instruments, the installation accuracy of remote sensing instruments must be guaranteed at all stages of ground design, development, and testing. [0003] Under normal circumstances, in order to minimize the influen...

Problems solved by technology

However, under normal circumstances, the development progress of the detection body of the remote sensing instrument often lags behind the development progress of the star structure and the vibration isolation device. This mismatch of development progress leads to the inability to directly complete the pin hole between the detection body, the star structure, and the vibration isolation device. It has brought great difficulties to ensure the installation accuracy of the remote sensing instrument to detect the main body
