Some of the most advanced GPS tracking devices have the ability to detect GPS signal interference. Products such as Azuga's Fleet tracking software include signal jamming detection.This protection can detect the use of GSM and GPS jammers. This feature helps prevent vehicle theft and can even be used to recover stolen commercial fleet vehicles.

　　Some drivers are authorized to use their work vehicles for personal use under certain circumstances. For example, many drivers take their work vehicles home every night. In other cases, drivers may take an hour off for lunch to run errands and eat while using company vehicles. In both cases and others, drivers use their work vehicles for personal use and may not want to be tracked. Many examples of drivers using GPS signal jammer are because they don't want to be tracked during these private times.

　　Many GPS tracking devices offer a "Privacy Mode" setting. This feature enables drivers (and dispatchers) to hide their driving activity for a period of time. Once enabled, the vehicle's position, speed and engine data will not be available. However, in special cases, such as accidents, data can be manually extracted to assist investigations. Providing a privacy mode reduces the risk of drivers using GPS jamming devices to protect their personal data from being leaked by employers.

　　Even without jamming detection, you can still capture employees with a GPS blocker. While drivers may think using a GPS scrambler will make them invisible, doing so will actually draw more attention to their behavior.

　　When an employee uses a GPS blocker, it shows up as a missed or interrupted trip on a live tracking map or trip history map. Additionally, if a Renegade employee has activated their GPS jamming device during only part of the trip, a line will appear from the scrambler's activation position to the position when it is deactivated. You can even create an exception rule to look for GPS signal errors and trigger email alerts in the event of interference.

　　GPS interceptors are dangerous, cheap and easy to obtain. Enabling privacy mode on your GPS tracker prevents employees from using GPS-interfering devices to block their movements during off-hours.

　　High-tech models of GPS tracking devices include signal jamming detection, and you can also detect employees using jammer gps by viewing the driver's travel history and live map tracking.
