Do Space Accelerometers Need Heat Shielding in the Thermosphere?

[JMcCarthy733]

Can someone please explain to me if highly sensitive space accelerometers need to be heat shielded before use in the thermosphere, if they already are heated shielded, or if their components are designed to work in those conditions?

If they don't need heat shielding can you explain how their components are still accurate in that extreme of a temperature range?

Thank you.

Typically, electronics are mounted on the inside of the spacecraft to an actively controlled isothermal panel to maintain temperatures inside a 'comfortable' range.

They're typically only shielded against radiation, not heat.

Hi there,

From my understanding, highly sensitive space accelerometers do not typically need heat shielding before use in the thermosphere. This is because they are already designed and built to withstand the extreme temperatures and conditions of space.

The components of these accelerometers are specifically chosen and tested to ensure they can function accurately in a wide range of temperatures. This includes the high temperatures of the thermosphere.

One way they are able to maintain accuracy in extreme temperature ranges is through the use of temperature compensation. This means that the components are designed to adjust and compensate for any changes in temperature, ensuring their accuracy remains consistent.

Additionally, these accelerometers are also often equipped with thermal control systems that help to regulate their internal temperature and prevent any damage from the extreme heat.

Hope this helps to answer your question! Let me know if you have any further inquiries.
