Obviously that is not the case. Again Big Brother is in your pocket. |
GPS itself is a 100% passive system. The problem was that those guys didnīt steal standard passive GPS receivers, they stole GPS devices that also served as trackers. Most GPS trackers use RF to transmit signals, some send data to satellites (but not to the GPS satellites). Some companies and communities use those trackers for fleet control.
