> Jamming can be pretty much eliminated by using phased array antennas.
citation needed there. GPS typical signal strength is -125dBm.
For ground based stuff, its pretty simple to overpower the band so that nothing can hear it.

A GPS Digital Phased Array Antenna and Receiver (2000): https://apps.dtic.mil/sti/tr/pdf/ADA452307.pdf
but thats still like -70dbm at best. That's about the level of being a few meters away from a wifi AP level of power.
a 1 watt(RF) jammer is going to cast a large cone of non-GPS even with a phased array antenna.
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.
