Satellite Tracking
Introduction
The automated vehicle tracking system (RVA), automated vehicle location (AVL, acronym for its name in English, automatic vehicle location) or operation assistance system, (SAE) applies to real-time remote location systems, generally based on the use of a GPS, GSM, Bluetooth, Wifi and a transmission system that is frequently a wireless modem. The European synonym is tele-location.
Online systems rely on wireless data transmission, which gives us great mobility as an advantage and allows us to have real-time communication of what is happening in our vehicle (Bluetooth, satellites, cell phones, etc.).
Off-line systems are those in which the information is not transmitted in real time; it is necessary to use a memory device to transport and analyze it.
High-end vehicles or electronic vehicles (Tesla among others) have these GPS and in case of theft you can ask the company for the location of this vehicle.
Context
In most cases, the location is determined using GPS equipment and the transmission to the control location is through communications technologies such as satellite, cellular or radio, using a transmission modem located in the vehicle as part of (or endorsed) to the GPS device.
Some other possibilities to determine the location of the vehicle, if not with GPS, are the use of DR (dead reckoning), Initial Navigation or RFID and even some combination of several of these technologies.
As a last case, we can find that these devices installed in vehicles to "track" or better known as GPS, are not always going to be there to work for us, it may be that in the few cases that exist they cannot work directly due to malice made by man just to steal. Always take into account everything we do with our vehicles and see if we really need it.
AVL Components
- GPS satellites:.
The vast majority of AVL devices use GPS satellites to obtain information on their geographic location, among other parameters.
