Automatic Vehicle Location (AVL) is a technologically advanced method of remote vehicle tracking and monitoring using GPS. Each vehicle is equipped with a module that receives signals from a series of satellites, and calculates its current geographical location, speed, and heading. This information can be stored for later retrieval or, frequently, transmitted to a central dispatch/control location where it is displayed on a high-resolution geographical map.

Automatic vehicle location (AVL) system GPS SPIDER, developed in Institute Mihailo Pupin combines GPS technology with wireless communications to deliver effective and affordable real-time vehicle tracking. GPS SPIDER keeps you informed on where your vehicle is and where it has been, how long it has been there, as well as on important information on your vehicles that can help you to quickly spot possible crisis or setbacks in fleet performance.

Most users think of GPS as a means of determining position, but the constellation of 24 satellites is also an excellent timekeeper. Each satellite contains two Rubidium and two Cesium atomic clocks. These are monitored against atomic clocks on the ground, and the whole system is continuously calibrated against the worldwide time standard, Universal Coordinated Time (UTC).

Count on the most accurate, dependable timekeeping system in the world – Global Positioning System - to keep your facility running smoothly. Our GPS Real-Time Clocks offer users pinpoint accuracy and perfect synchronization across their facilities.
