GPS fleet management is the product of three useful technologies. Global Positioning System, computerization, and cellular communication are by themselves independent technologies that have many uses. But [link widoczny dla zalogowanych] when these technologies are integrated, a new product is created. This technology enables the real time monitoring of the [link widoczny dla zalogowanych] location of assets. Fleet management refers to the fact that there are a lot of these assets that could [link widoczny dla zalogowanych] be delivery trucks, taxis, buses, and military vehicles. The purpose of managing the fleet is to realize business expectations in an efficient manner.
The GPS lies at the heart of the management application. The GPS is just a radio receiver with a lot of built-in smarts. It takes its information from a constellation of satellites orbiting the earth. What the [link widoczny dla zalogowanych] satellite does is to provide position information to earth bound GPS receivers. When a receiver has four of [link widoczny dla zalogowanych] these satellites in view, it is able to calculate a solution which is actually [link widoczny dla zalogowanych] the position of the vehicle that is accurate to ten meters or less.
The location of the moving asset that contains the GPS unit is transmitted to whoever is managing the vehicles using cellular communication. Older systems use SMS. Newer management systems utilize wireless internet via GPRS or 3G.
In front of the manager is the base station. It is composed of a computer that is running mapping software. Updates from the fleet show up on the map. Other things that are important for the business are also shown on the map. These are roads, buildings and the location of customers.
One important [link widoczny dla zalogowanych] distinction of this management application over GPS tracking is the presence of additional sensors. For example, [link widoczny dla zalogowanych] delivery trucks have sensors that reports every time the cargo door is opened. The trucks can also be equipped with RFID sensors. It enables management to monitor in real time when and where a piece of cargo was delivered. Another example is [link widoczny dla zalogowanych] a sensor on a bus able to report the event of stopping in a bus station and how long a trip is between stations. The real time aspect of knowing where and what time an important event took place is the essence of GPS fleet management.
Back to the base, the events that are reported are being analyzed in [link widoczny dla zalogowanych] real time on the computer. All sorts of optimizations are performed in order to [link widoczny dla zalogowanych] maximize the use of the assets. Studies of the benefits gained when the application is used showed significant savings in operational costs. There are savings in fuel consumption and more importantly, when less fuel is used, potential pollution is averted.
Another user of application is the military. This gives the commander a strategic advantage in knowing where his forces are located all the time. He adds to the advantage when he uses real-time intelligence data to better position his units. This way the military objective is met with [link widoczny dla zalogowanych] the least cost in terms of casualties and equipment damage.
GPS fleet management is technology that has to wait for computerization to mature. Now that computers are cheap and affordable, what was previously purely military equipment is now finding its way in a lot of civilian applications. The military should be credited for making GPS technology publicly available.
