Embodiment Construction

[0027] The method for assessing the risk of deep charging of satellites according to the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0028] Firstly, step 1: sampling the occlusion and parts to be evaluated inside the satellite into a flat structure or a coaxial structure, and obtaining the thickness value of the medium.

[0029] figure 1 Middle (a) and (b) are the dielectric structure models sampled by the evaluation method of the present invention, for example, all kinds of common cables in the satellite system can be sampled as figure 1 The coaxial model shown in (a), while the printed circuit board, etc. can be sampled as figure 1 The plate model shown in (b), figure 1 In (a), the medium 1 is surrounded on the inner core 2; figure 1 In (b), above the medium 4 is the shield 3 , and below it is the ground layer 5 .

[0030] As an example, in this embodiment, a printed circuit board medium in ...

Abstract

The invention belongs to the field of spacecraft space environment protection design and space radiation environment effect evaluation for in-orbit management application, and specifically relates to a method for evaluating the risk of satellite deep charging. The method is suitable for charging evaluation for mediums such as slab structures and coaxial cable sleeves in various stationary orbit satellites having spin stabilization platforms and three-axis stabilization platforms. On the basis of a current deep charging evaluation method based on a current balance theory, the invention provides the method for evaluating satellite deep charging by use of satellite high-energy electron continuous data which is actually measured, and overvaluation and undervaluation caused by the commonly-used charging evaluation method based on the balance theory can be avoided, so that the method provided in the invention is more scientific and has higher practical application value.

Description

technical field [0001] The invention relates to the field of satellite in-orbit space radiation environmental effect management, in particular to a method for evaluating the risk of deep charging of earth orbit satellites. Background technique [0002] Elements such as high-energy electrons, high-energy protons, and heavy ions in the space radiation environment will cause radiation effects and hazards to satellites. In addition to causing radiation dose effects on satellites, high-energy electrons in space will also penetrate the skin of the satellite and deposit in the insulating material or non-grounded conductor inside the satellite to cause charging, that is, deep charging of the satellite. The deep charging of the satellite will be like the electrostatic charge on the ground. When a certain tolerance value is exceeded, a discharge will occur, just like the electrostatic discharge on the ground. During the discharge, a large amount of charge and electromagnetic waves wil...
