To me, NF refers to "noise floor".

Lets see him go below that.

GPS received signals are among the lowest "power" signals we currently
grab. They sit just above the noise floor.


It might to you, but in this context it means either Noise Factor or
Noise Figure.

Of course you can go below the Noise Floor, and in some circumstances
and modes the signal is receivable and decodable.

30dB below the noise floor....

The answer to all your needs. Less is more. That Chef's Hat
conglomeration is overkill.
