that's called jamming and was addressed by the comment. if you wear very narrow blinders and point your face right at where you want to look, then the enemy needs to install their spotlight right ahead of you instead of just anywhere in front.

It is a mitigation that may help, but not foolproof: someone can jam or spoof from the sky. Current areas where jamming is being detecting. * https://gpsjam.org https://gpsjam.org

  This jamming isn’t from the sky though. Incidentally, there has been a recent escalation in this: over Iraq commercial airline pilots have been reporting increasingly successful GPS spoofing, with GPS positions being shifted by tens or hundreds of nm, the clock being shifted, etc. In some cases this has exposed bugs in aircraft software where it has not successfully recovered the GPS position even after leaving the affected area, leaving them with degraded navigation all the way to the destination. This is not as dire as it might sound, as there are plenty of other ways for an aircraft to determine its position, though it certainly reduces the margins for error in some cases. But it’s interesting because such spoofing should be extremely difficult to carry out successfully, especially on a moving target like an airliner.

Encryption still won’t stop it. You will need many blinders to get a fix on enough satellites.

Or make a stronger spotlight and point it at whatever is directly in front of you, to blind you with reflected light.
