Satellite structure protection against space radiation

[titius]

Hi,

did anyone have an idea on wich criteria to rely for choosing the thickness of an aluminium structure to protect the satellite subsystems from space radiations.


Thanks

How much are you willing to spend to build, test, and launch the added weight? Aluminum is not much of a shield, and the general approach is to harden the electronics.

I suggest that you read Space Mission Analysis and Design by Wertz and Larson.

Thanks for your answer, but in certain cases it is not possible to harden all the electronics from all the corners.
I think you already know that the radiations comes from all of the possible angles due to the rotations of the satellite. So I think that a minimum aluminium thikness is required to dcrease the radiation intensity.

Not sure what you're refering to; hardening of circuits are usually inherent in the design and are not dependent on angle.

I'd say he trying to say that certain electronic component in his design can't be hardened against radition without some reduction in intensity.

I'm referring to "from all the corners"
