It really doesn't take much! One of my favorite GPS jamming incidents of public record is the one at the link: http://www.gpsworld.com/gpsworld/article/articleDetail.jsp?id=43404 For another look at things, please see: http://www.gpsworld.com/gpsworld/article/articleDetail.jsp?id=43432 Bringing this back on the topic of time :) The Fall 2007 issue of the magazine "Inside GNSS" has an interesting article "Fuzzy Time - GPS-Based Synchronizers in the Presence of Interference" For a CW signal, a GPS timing receiver's performance begins to degrade when the interfering signal is at a level of -87 dBm. With an FM interference source, it starts to degrade at -106 dBm. Well worth the read if you can find this magazine.
