The terms and definitions defined in GB/T 32452, GB/T 30114.2 and GB/T 44385-2024, as well as the following terms and definitions, apply to this document.

3.1

The ratio of the radiation dose that causes a material or device to fail due to radiation to the ambient radiation dose at the actual location of use on the satellite.

3.2 Watchdogtimer;WDT

A timer circuit that uses hardware or software to generate a reset signal and restart the system when a program malfunctions.

3.3 wake effect

When a spacecraft is orbiting in a low-altitude, non-polar Earth orbit, its speed exceeds the speed of sound of ions, causing [the following to occur] within the spacecraft.

The phenomenon of an ion depletion region being formed in the opposite direction of motion.

3.4

During strong solar activity events such as coronal mass ejections, the solar wind compresses the Earth's magnetopause to below the altitude of geosynchronous orbit, leading to...
