Introduction

This document presents a methodology for the assessment of radiation effects from commercial off-the-shelf (COTS) devices used in low Earth orbit (LEO) satellites. many Small satellites (< 180kg) and nano-satellites/micro-satellites (1kg~50kg) are launched to space radiation that exists but is less than high-orbit space radiation LEO orbit. It is common for designers and manufacturers of such satellites to use COTS semiconductor devices for their satellite components and electronics. sub circuit board. Using nanosatellites/microsatellites and cubesats [1.33kg×(1U~3U)] (volume 10cm×10cm×10cm is called 1U) industries or units include IT companies, mobile phone and Internet industries, universities and research institutions, etc. Satellite manufacturers prioritizing investment efficiency are also aiming to extend mission lifetimes (up to 3, 5 and 10 years) more than with Nanosatellite Educational and technical demonstrations of satellite/microsatellites have longer mission lifetimes of one year, as is common. Compared with higher orbits, even if the space radiation conditions of LEO are relatively good, the long mission life of LEO is not good for small nano satellites. COTS devices on satellites/microsatellites and cubesats constitute a key radiation environmental constraint. While methods exist for evaluating the radiation susceptibility of space devices, methods for evaluating COTS devices for use in LEO satellites are limitations, and these methods are usually based on the use of existing devices. This document provides guidance for evaluating the radiation tolerance of COTS devices and can help increase confidence in long-term mission lifetimes.
