Most field service reps are aware of the rules and penalties for using GPS jamming device to manipulate their location or driving log. However, some drivers and representatives who did not want to be tracked by managers inadvertently used GPS jammers. These actions could have a more dramatic impact.
Ensuring driver safety, reducing fuel costs, managing on-time deliveries and asset tracking are just some of the concerns most managers have. While Global Positioning System (GPS)-based trackers make the field service manager's job easier by improving road efficiency, the technology itself is not secure from tampering.

For example, what do pilots who lose air navigation signals, ships at sea show the wrong location, and delivery drivers avoid tolls? All three cases involve GPS signal jammer.that tamper with or block GPS signals.

What is interference?
First, let's understand what GPS is and how GPS tracking works. Currently administered by the U.S. Air Force, GPS is a radio navigation system that uses the Global Navigation Satellite System (GNSS) network to use time data sent from dozens of satellites in space equipped with atomic clocks. Each satellite transmits signals that GPS receivers on Earth use to communicate their positions.

Occasional satellite glitches can corrupt these signals, but a more intentional cause is GPS interference. cigarette lighter gps jammers are plugged into the vehicle's cigarette lighter port and work by broadcasting noise on the same frequencies used by satellites. In this way, the GPS receiver cannot receive satellite signals. Depending on the strength of the gps scrambler, it can cover GPS reception for miles or yards.
