That question is pretty easy to answer with just a little reading at Wikipedia or a Google search. What reading have you done about this already? Can you post links to your reading, and ask specific questions about which parts you are not understanding yet? Thanks.

Yes, I’ve read this article from Wikipedia: https://en.wikipedia.org/wiki/Global_Positioning_System. From it I conclude that only P code is encrypted, but I also read some articles about cryptographic civil GPS signals. This is beyond my understanding.Senmeis

What is it about the civilian GPS signals you do not understand? Why? Are you looking at the new so-called high precision 'safety' signal which is not encrypted AFAIK. I'm not clear on what there is out there to make this hard for you.

I believe that @davenn can speak to this because GPS receiver systems from a large company, Trimble, has very high accuracy systems - example: for optimizing the drilling (planting) of corn (maize). Dave works for them still, I think.

At any rate he probably has some high quality input here.
