Research on Improving the Technology of Producing Radiation-Shielding Materials for Satellite Systems of Rocket and Space Technology

Abstract

Space technologies have become part of a society that increasingly relies on the effective operation of various space systems: weather forecasting, exploration of minerals, monitoring of the environment, development of telecommunications and television, and, of course, ensuring defense capabilities.

The functioning of onboard electronic equipment (OEE) is influenced by numerous factors during its operation. The impact of ionizing radiation fields of space is particularly significant. The use of semiconductor microelectronics products as the component base of space systems has made it relevant to assess and predict the radiation resistance of nodes and assemblies to the radiation effects of space.

The widespread use of functionally complex products in the radio-electronic equipment of spacecraft, for which it is quite difficult to perform the entire range of work to meet the requirements for radiation resistance, poses a number of problems in the production of a relatively full range of radiation-resistant integrated circuits (ICs).

This is due to the fact that many microchip manufacturers have stopped producing radiation-resistant products, while tools for developing and debugging ICs of commercial quality are widely represented in the market of electronic components.

Thus, there is currently a trend towards the use of commercial microelectronics products in the radio-electronic equipment of spacecraft. This provides a number of advantages over radiation-resistant microchips, as commercial microchips have greater information resistance and are cheaper.
