> GPS signals are relatively low power (American GPS broadcasts at 25 watts and are ~10-15W at sea level)

Did you lose 16 orders of magnitude for the sea level values? GPS signal strength on the ground is usually below -135dBm per square meter. That gives you a couple of femtowatts with commonly used antenna, if you're lucky.

Easy to jam doesn't begin to describe it.




Shit, you're right. I blame the time change.
