GPS Tracker for Fleet Management

If your business depends on having vehicles ready where you need them, when you need them, a GPS tracker can help you manage your fleet and keep drivers more accountable. The Global Positioning System (GPS) is a world-wide system formed by dozens of satellites and tracking stations. It started out as a tool maintained and used only by the military, but has evolved into an essential guidance tool that people can carry in their pockets. However, today’s commercial GPS tracker systems allow business operators to monitor their fleets for security and efficiency.

GPS Tracking

Global Positioning System tracking works out exactly where your car, truck or limo is at any given time. It can be placed anywhere inside the vehicle via a fixed or portable unit. In addition to providing a fixed position, GPS software tracks the movement of your vehicles. So, you can monitor the route and progress of a delivery or pick-up, or to track valuable assets during transit.

A GPS tracking system uses the Global Navigation Satellite System. This network of satellites uses microwave signals to communicate with GPS devices by either transmitting or receiving location information. In general, it allows the GPS tracker to give the location, speed, time and direction of a moving vehicle, which enables a GPS tracker to provide managers with real-time and historic data on vehicles and their drivers.

How it Works

Ground stations around the globe help monitor and transmit GPS tracker signals from satellites continuously orbiting Earth. The satellites transmit microwave carrier signals that users of GPS technology can receive. These signals are converted by GPS devices such as trackers and cell phones and returned to the satellite, which lets the GPS system estimate the vehicle’s position, velocity and time.

The calculations are made possible by a simple mathematical concept called trilateration. In order to calculate position, the GPS receiver has to know the location of the place tracked by three satellites in geosynchronous orbit (stationary) above the earth. Further, it has to know the distance between the place being tracked and each of the three satellites. GPS trackers contain multiple receivers that pick up data from many satellites simultaneously using electromagnetic radio waves traveling at light speed.

Active GPS for Real-Time Tracking of Your Assets

Active GPS trackers are also called real-time systems because they automatically update a central tracking portal. This is widely used for commercial applications, especially for fleet and delivery businesses, because it is better at tracking vehicles and people. Trust but verify is an old adage that applies well to employers who want to give their associates the benefit of the doubt, but also need a way to monitor employee behavior and asset management to streamline activity across a fleet of vehicles.
