A GPS Tracking System is made by 3 main components:
-A GPS device or GPS Tracker, which receives the location information and then gives it to a software application.
-A data transmission system, that takes the data supplied by the GPS Tracker, and delivers it for the software application.
-An Application Application, which presents to the users the info recollected through the GPS Tracker in several formats including maps and reports.
This short article will present the main elements of gps tracker voiture, and will start expanding on the first component: GPS Trackers. It will require me this article and also the next one to get in detail over GPS devices.
In this section I am going to define what a GPS Device, and exactly how they work; i then will introduce the types of trackers, what features bring various kinds of trackers and my opinion when it comes to each kind. At its simplest definition, the GPS device, or better the GPS tracker, is definitely the component in command of finding the details about the location of the vehicle, and providing this data for the GPS Tracking Application with the Data Transmission System (that will be explained in coming articles).
GPS Trackers are generally small boxes (metal or plastic) that can be the dimensions of a man’s wallet, or even a little bigger. Them all need one or more antenna (GPS antenna), and most of them need yet another antenna to enable the information transmission module. So this can lead to an initial classification of GPS Trackers:
Full satellite trackers. This type of trackers uses satellites to receive and transmit data. Hybrid trackers. This type of trackers uses satellites to get location (we will see some variations here later in this article), and the other approach to transmit the info (a data modem, a data port to download the data, etc).
On the next article I will expand on these concepts. So, the key task of any GPS Tracker would be to provide information from the location of a vehicle or perhaps an asset, or a person. The position of the units is usually acquired through the GPS satellites, but there is another method based upon triangulation with cell towers to calculate locations. Getting the location from satellites is regarded as the accurate mechanism, providing a minimal margin of error most of the times (from 2 as much as 50 feet). GPS location can be obtained akrvuz on earth. The only real down side for this location technology is the fact that GPS antenna must have a view for the sky. For instance, if the vehicle gets into a garage, most probably there is definitely not GPS locations available.
Having the location according to a triangulation with the cell towers (the ones that are also utilized by our cell phones to transmit voice and data) has a bigger margin of error (as much as a few hundred feet), which makes it a not very accurate location mechanism. This kind of location also requires the actual existence of the named cell towers to work. The upside of the mechanism is that it will perfectly work within buildings, which is not the case for GPS satellite location. Some GPS Trackers are created to assist both location mechanisms, making a new concept called Assisted GPS (AGPS).
You can find mainly three varieties of GPS Trackers: Passive Trackers, PING Trackers, and Live Trackers. Also, some devices get more capabilities than merely getting the position of the vehicle.
In this post I have dissected a GPS Tracking solution into three main components: a GPS Tracker, a data transmission system, as well as a GPS Tracking application. I have also started exposing the details of GPS Trackers, specifically the two main ways to locate a vehicle. Finally, I introduced two more elements to think about in GPS Trackers: kinds of trackers and advanced highlights of a GPS device.
