The Global Positioning System (GPS) is a satellite-based system that can identify the location of a GPS device installed anywhere on the ground in terms of three parameters: longitude, latitude, and altitude. It is simple to understand and is used for advanced navigation. If you have a GPS system installed in your car, the control center can learn your position through the signals transmitted between the satellite, the installed GPS device and the control center. Real-time position data is provided by some 24-34 satellites in space. These satellites map the entirety of the earth in terms of longitudes and latitudes and use these landmarks as driving or navigation aids. This data is useful in a variety of practical applications, most notably in transportation or for fleet tracking purposes. GPS is used with Geographic Information Systems (GIS), which is the digitized mapping of spaces and structures, for greater effectiveness.

With GPS installed on buses, trucks, ships, cars, and other moving vehicles, you can easily check their routes and how long they stop. In short, it helps in fleet tracking and management. GPS fleet management system, when used with GIS, can help warn of problems ahead. A vehicle with a GPS device can know about the traffic jam on the road it is moving on (which is possible thanks to GIS mapping). In the same way, ships on the high seas can navigate with great ease and also know the weather conditions that will be found on their route. GPS tracking devices also help detect stolen vehicles. After reporting the incident to the police, you can provide the crime reference number to the company providing GPS services and allow them to coordinate with the police to track the vehicle. This helps maintain control and coordination, increases efficiency and meets emergency requirements.

GPS-based fleet management software leads to better route planning and optimization, thus reducing transportation costs. Fleet tracking, better fuel usage, routing, response time and better customer service are some of the beneficial aspects of this technology. GPS fleet management has resulted in the elimination of excess fuel consumption and thus reduced carbon emissions. When applied around the world, this technology is likely to reduce your carbon footprint.

These fleet tracking systems are now also available as mobile apps. Many well-known mobile phone companies now have features enabled for these apps. These GPS based devices take you to your destination from the easiest routes and never let you lose direction. Mobile applications offer great flexibility of operations for managers or owners of the fleet of vehicles or ships. These can be used even when on the go.

GPS apps have a variety of other interesting uses as well. These are used by wildlife experts studying the travel routes of birds and animals, by law enforcement agencies while on the trail of criminals, in unmanned aerial vehicles, and most importantly by transport companies for fleet tracking purposes.
