Advanced GPS
Of each application in the GPS units, the navigational, and vehicle tracking systems have brought to you, some new technology designed to fit the needs of the average person. GPS today fits in any car, fleet, police cars, ambulances, etc. GPS units are considered Automatic Vehicle Locating Systems (AVLS) or VTIS, Vehicle Tracking and Information Systems. They are also called Mobile Asset Management Systems or MAMS, and GPS. The systems provide you with a wide variety of tools that help you improve your operation efficiency and the use of your vehicles.
When you turn off the SA, it improves the precision of your system so that you can reach up to 30-metres. It makes a great position sensor for any vehicle-tracking device without DGPS overhead.

GPS devices can be used for navigating or tracking a vehicle. The GPS enables a base station to track a vehicle or vehicles without any intervention of the driver. The driver can easily arrive at his or her destination without any problems.
Navigation and tracking devices are similar in many ways. Navigation systems enable you to use graphic maps on a display screen to find your way around town, a city, or state. A tracking device uses a well-structured technology to help you track your vehicles. The technology is used irrespectively. VTS comprises of three subsystems, I.e. an in-vehicle unit or IVU, base station, communication link, etc. The IVU has added features including a position sensor and intelligent controller. These are used together with interfaces to help you connect to the communication links.
The network overlay systems utilize mobile units or phones infrastructure to locate their vehicles. Cell centre use other software programs and hardware to assess TOA or time of arrival as well as AOA or angle of arrival, of the radio signals from the vehicles to compute the positions of the driver or vehicle. The data retrieved is submitted to the tracking centre via a conventional or cell link. Some companies locate their vehicles by computing the time differentiation for the signals from the cell centre in order to reach the vehicle.
The computed information is created within the IVU in which the position information is channeled or submitted to the tracking centre via a cell link. DRL is commonly used to track vehicles. This direct radio link is a system that is dedicated to radio infrastructure and it is often used with IVU to finalize the vehicle’s location.
Since these last techniques are, limited GPS has embedded receivers that supply complete position coordinates for any point and without any restrictions to an area.
IVU structures comprise of controllers that interact with the receiver of the GPS and collects coordinates at the predefined intervals. The information is processed and submitted to the communication links. The base station uses a high-speed unit to run the VTIS applications and software that is capable of receiving the position data from the vehicle and the display is shown on a digital map.
