Add in coding gain over 1 second (a code 10 million chips long), and that gives you an extra 70dB. Now it's getting hard to jam.

Downside: This only works if your movement over the 1 second period is predictable, to a small part of a wavelength. If you're moving unpredictably, you'll have to give up a few db's of coding gain.
