Problems solved by technology

International environmental detection for MEO orbits is also a detection in which a single detector only has a single function
[0014] At present, there is no integrated detection device for MEO orbital space environment and effects at home and abroad, and it is impossible to realize that one detection device can detect multiple space environments and effects

Abstract

The invention discloses an MEO (medium Earth orbit) space environment and effect integrated detection device, and the device comprises a cylindrical detector housing, a collimation blocking layer covering the housing, and all detection units and function layers in the cylindrical interior. The collimation blocking layer is provided with an opening which is used for receiving the emergent space environment particles. The interior of the housing is alternately provided with a metal layer and an insulating layer, wherein the insulating layer forms an internal space, and the internal space is usedfor storing a dosage sensitive element, a single-particle turnover detection element and an internal charging potential monitoring piece. The device is simple in structure, has many functions, is light in weight, and is low in power consumption.

Description

technical field [0001] The invention belongs to the technical field of space environment and effect detection, in particular to an integrated detection device for medium earth orbit space environment and effect. Background technique [0002] The medium earth orbit, also referred to as MEO orbit for short, refers to the earth orbit area with a height of about 21528km, and a large number of navigation satellites are distributed in this area. [0003] In addition to vacuum, temperature, and solar electromagnetic radiation, the MEO orbital environment also has a large number of charged particles. The sources of these charged particles are mainly the outer radiation belt of the Earth's radiation belt, solar cosmic rays and galactic cosmic rays, as well as a small amount of space debris and micrometeoroids. [0004] The space particle radiation environment mainly refers to the charged particle environment of various energies encountered by spacecraft in orbit, and consists of two...
