GPS Tracking Devices


What is GPS?

GPS is an acronym for Global Positioning System, a system of satellites and receiving devices that compute positions on the Earth. Three people invented the technology for the United States Department of Defense: Ivan A. Getting, Bradford Parkinson, and Roger L. Easton. Initially, they developed the technology to help military personnel. Now, technology is in everything from vehicles to mobile devices to everyday appliances. GPS Tracking Devices leverage GPS technology to monitor the movements of a person or a vehicle, their location, and movement.

How do GPS Tracking Devices Work?

For example, navigation systems use GPS technology. The technology uses signal transmissions and mathematical triangulation to pinpoint the location. Similarly, GPS tracking devices use information from orbiting satellites to determine the exact longitude and latitude of the device. In some situations, private investigators use tracking equipment to monitor the travel activities of the subject’s vehicles.

GPS device tracking capabilities are not limited to tracking vehicles, as they can even be used to track the subject themselves.

The tracker comes with a companion app that allows you to see where the device is located on a map (with an accuracy of 16 feet). Also, you can set up text message alerts to check in on the status. The app tracks things such as the driver going over a set speed limit. Also, it will notify you when the device senses vibrations or when the power is off. Plus, you can set up a geo-fence to be notified when the device goes out of a specified area.

The body of the device is lightweight but sturdy. It has five magnets that provide a total of 80lbs of pull. This helps ensure it stays attached to the car or other vehicle. The battery life on the iTrail is impressive. It will last up to 265 days on standby. Plus, it is rechargeable so that you can use it over and over again.

The iTrail is excellent for business owners who want to track their vehicles. Also, concerned parents who want to keep track of their teens while they are driving, on a trip, etc.

The package includes the iTrail device, one USB cable, and one USB wall adapter.

What do Private Investigators Need to Know?

Full-service private investigation agencies will often receive inquiries regarding using GPS tracking devices for their clients and prospects. It is a good idea to have at least one investigator on staff familiar with how the devices are used and the laws in your state.

Proper use includes locating the subject’s vehicle and placing the device in a hidden area such that it won’t be discovered or fall off when the vehicle starts moving. In addition, it is vital to be skilled at retrieving the device and interpreting the data and results once retrieved.
