GPS jamming is certainly a fun problem to deal with... I've been getting into GPS for timing data, and especially if you're building a global network or coordinated system using GPS as the time source, you have to account for it if you care at all about time stability. Apparently (I haven't had this happen personally, yet) many truckers install GPS jamming cigarette lighter accessories in their trucks when they want to mask their location from trucking companies that track them everywhere. That can wreak havoc on GPS receivers at facilities, especially if you have, say, a logistics building right next to a datacenter.
