GPS receivers calculate velocity and time as well as track the actual location. The GPS control segment of the Positioning System is made up of many tracking stations all around the world. It uses four or more satellites to determine the position of the GPS receiver in any line of sight throughout the world. GPS systems are now employed in various applications, including air planes, mobile phones, car tracking systems, navigation systems, and mapping.

The GPS Control Segment refers to the functionality provided by the ground stations that serve as an interface for communication between satellites. The GPS control segment comprises a worldwide network of ground stations that track GPS satellites, monitor their broadcasts, conduct analysis, and relay commands and data to the constellation.

 

How Does It Work?

GPS trackers work in the same concept, but instead of displaying information on the device, the microprocessor calculates the device’s location and sends the result to a server over the Internet via the global GSM mobile network. Users can access and explore current and past tracks, speeds, and alarms on their devices through their server platform. This information is then delivered over the Internet and shown on a desktop app or an iPhone or Android app on a user’s device.

Business owners may use GPS tracking systems to track the whereabouts of their fleet and monitor staff behaviour. Small-time users will benefit from GPS systems as well. Families have utilized GPS devices to keep track of the elderly, children, and pets. To keep their luggage from getting lost or stolen, travellers have affixed GPS trackers.

 

Customers must choose whether they want an active real-time tracker or a passive tracker when purchasing a GPS tracker. Users of passive trackers cannot follow every motion made by a tracked person or object. The data must be gathered and then transferred to a computer. These trackers are usually less expensive because they don’t require a monthly fee.

 

Dispatchers use the GSM cellular network to receive real-time information, allowing them to keep a close eye on their assets or valuables. The cellular network services are paid for at monthly rates. If the GPS satellites signal is obstructed by being indoors or by a structure, and there is no sky, the device looks for cell tower signals. It uses cell tower signal strength triangulation to estimate a general location.

 

How does the GPS tracker determine the device’s position?

In metropolitan regions with adequate mobile traffic and cellular tower density, a precision of up to 100 meters can be achieved. Rural and remote places with fewer towers per square mile may see miles between base stations and thus incorrectly determine position, often displaying a location that is miles distant from the device’s true location.

GPS tracking devices can be installed in vehicles, assets, people, and valuable items, and they can be fixed or portable. GPS provides precise location, speed, and time information. As a result, a corporation can use GPS tracking to track the route and progress of businesses and parents to keep track of their children’s whereabouts and monitor precious assets.
