How does a GPS tracker work?

To understand why a GPS tracker is such a versatile and practical device, you need to know how it works. First of all, a so-called GPS signal is required, which is transmitted. Now there are two ways in which communication can take place: either with a satellite or with a SIM card.

A smart device

The GPS receiver is built into the GPS tracker. The GPS signal permanently determines the current position so that the device knows exactly where it is. Now either a cell phone or another server receives the data from the GPS receiver, such as speed, time and, of course, the position. Specially equipped GPS trackers can send a signal by text message or phone call in the event of an emergency call from a person. The mobile Internet helps to track a vehicle or a person at short intervals. The transmitted data for the position can be viewed either on the PC or on the cell phone. The coordinates are usually displayed as a marker on a map.

Track markers on the map

There must be a GPS signal in order for localization to take place. Information about the GSM base station can help to determine a position if there are inaccuracies in the location, and are often equipped with this function when it comes specifically to locating people.

Visual tracking

A GPS person tracker releases the current position if, for example, a request is sent via SMS. Many manufacturers offer their own page on the Internet so that the position can be viewed on a map. This also makes it easier to track the route you have traveled or walked so far.

Use online tracking portals

A so-called tracking portal is not only required for people, but also for animal tracking or vehicle tracking. With such an online portal, the user enjoys several advantages at once. The peripheral data and the current position of the GPS tracker can be optimally viewed. Numerous reports and functions are often available that allow optimal and precise route tracking. In the same way, information is provided about the standing times and journey times. An alarm can be switched on if a certain area is left. The collected data is optimally summarized on such portals. It is possible to configure the tracker on the portal, which also works remotely. In order to manage these professionally, a proper program should always be used.

There are certainly different forms of this. On the one hand, there is the English location portal from China or the USA with an unknown server location, inadequate data protection and poor reliability. On the other hand, there are professional fleet management software variants where, for example, data protection and very high reliability are important, e.g. for couriers, pharmacy services, newspaper deliverers, medical transports, etc. The costs are different from those of the simple tracking app for amateur athletes.

GPS monitoring provides security

A GPS tracker is also often referred to as a direction finder, tracking device, sniffer dog or tracker. Not only can you better document and track your own sporting performance when jogging, running or on tours, but the device is much more than that. There are many areas in which general safety can be improved by GPS monitoring. For example, if parents are worried about whether their children have arrived at school safely, a GPS tracker is particularly recommended. Of course, this also applies to the way home. In an emergency, people with dementia can be found more quickly. If accidents occur or a call for help is necessary on vacation or on an excursion, the device provides just as much security. This provides ideal theft protection for cars, motorcycles, bicycles and other vehicles. Luggage or other valuables can also be easily found with a GPS tracker and GPS monitoring.
