If your business has something to do with moving people or cargo it would be a good idea to know when and where your vehicles are located. There is a way to do this in real time and it is called vehicle tracking. When real time monitoring is not important, a GPS logger GPS loggers can do the same thing.
Loggers work by recording the occurrence of an event. In our case the event that is important is the vehicle's position in time. The object that generates the event is a GPS. Loggers store the events fed into it in its memory. The logger and GPS are usually combined into one package and usually have a very simple user interface. In fact, most loggers would only have a power switch and a button to start or stop data logging.
Position data that are saved by the logger is usually a text based standard. Such standards are NMEA, KML or GPX. GPX is a way to format position data so that it conforms to XML specifications. KML is another XML compliant format that is used by Google Maps. NMEA is a protocol that is understood by most electronic navigation equipment. A useful NMEA sentence is PVT which stands for Position, Velocity, and Time. Position is usually stored as XY coordinates or longitude - latitude pairs.
The data from the logger are downloaded into computers at regular intervals. The frequency depends on the memory capacity of the logger. The data is read by software and analyses it. The data can be displayed on computer-based maps.
Going back to the data, we recall that the logging unit stores individual PVT sentences. This information can be mapped right away because longitude - latitude pairs are already embedded in the sentence. We will see on the map where the vehicle went and the time spent in going to the location.
For business purposes, it is now possible to monitor the performance of the vehicle's driver. You can find out if the driver was following the prescribed route or not. You are also able to monitor if the driver was obeying company policy on speed limits. The device will tell you if your driver spent more time stopping rather than being on the move.
GPS logger GPS loggers saves position information in memory. These are very easy to use devices and have many useful applications. While not capable of real time monitoring, analysis of the data can generate many insights that are useful for business.
