The GPS tracking system uses 24 solar powered satellites that continuously orbit Earth. Their routes are mapped so that anywhere on Earth, at any time there are at least four satellites "visible" in the sky. Satellite signals travel at the speed of light. Using the mathematical principle called trilateration, GPS offers the ability to locate and track a subject, pinpointing longitude, latitude, ground speed and course direction. The system operates independently from telephone or internet reception and requires only a GPS receiver. The latest stage of accuracy enhancement uses the L5 band and has an ability to pinpoint to within 12 inches (30 centimeters). To save energy, real-time GPS trackers do not send a stream of data but report positions at predetermined intervals. Typically, the fastest reporting interval is ten seconds.

In order to get GPS coordinates from video, you will need software that can embed geolocation data into a video file as it is being recorded. Many modern cameras have built-in GPS capabilities that can tag video files with location data automatically. Using software, this metadata can then be extracted after recording to view the GPS coordinates.

GPS fleet tracking is a system that uses GPS technology to manage and monitor a fleet of vehicles by installing GPS receivers in each vehicle. The receivers are used to record the locations, movements, and other metrics like idle time, speed and route of the vehicles. This information can be used to enhance safety, comply with regulatory requirements, improve resource allocation and optimize route planning.

The cost of a GPS tracking system will depend on the type of system, scale and features. More advanced systems will naturally cost more and the price will also increase for every GPS receiver needed. If you wish to add additional features like real-time analytics, you will also incur higher costs.

Yes, police can use GPS to track suspects. However, in most cases, they will need some form of legal authorization in order to do so, as tracking can violate people’s right to privacy.

The accuracy of a GPS tracker is dependent on factors such as satellite visibility, the quality of the GPS receiver and environmental conditions. Environmental conditions that can interfere with signal reception can include dense forests, tall buildings and other urban obstructions. On average, a basic tracker should be able to provide a location that is accurate within a range of 10-33 feet (3-10 meters).
