GPS Tracking refers to a Global Positioning System. It entails a network of 24 satellites in orbit and devices on the ground that can establish a person or object’s location on Earth with astonishing precision. GPS Tracking tracks three separate data sets: positioning, navigation, and timing. 

You may not realize it but this technology has been around for a long time. GPS was originally created for military use in the 1960s. In 1983, GPS became available for public use, and the technology has only grown from there. Today, it’s used for everything from precision military maneuvers in foreign lands to kids playing mobile phone games in your neighborhood.

Since the GPS data collected is generally the same, the speed at which you can access the vehicles location provides is one benefit. You can make better dispatching and scheduling decisions when you have good data to use.Live systems don't require any installation of a local antenna, computers to store the data or tracking software on the client PC. Live truck trackers generally are viewed through a convenient website. Another benefit is that vehicles don't have to return to a central location to get the data. Many fleet managers don't need live data to make decisions but the trucks don't return to a central location with any frequency. GPS data that is over 2 weeks old is really not of significant value to most fleet managers. The price of live tracking systems is subsidized by the monthly fee that goes with them. This keeps the capital investment lower. The primary disadvantage to live GPS trackers is that there must be a monthly fee. The monthly fee is used to cover the cost of moving the GPS track and telematics data across the cellular network, subsidizing the equipment investment, development, customer service and profit for the service provider. Because there is a monthly subscription service vendors are motivated to support your account and address needs.
