you can't have authentication in a one way system. satellites send days, planes receive it, but never send anything.

You can have a digital signature, so the recievers know it's legit

yes of course, but that isn't authentication.

Playing with semantics a little, it can be thought of as the satellite authenticating with the client using the signature as password.

You can't copy a signature, since it is different every time the signed content is different. You need to have the correct key in order to make a valid signature.

If you've figured out how to do that, a lot of governments would pay you a lot of money for your solution
