Recently, devices related to GPS satellites have become very popular: car and tourist navigators, as well as tracking devices - GPS trackers. The latter can be used both in cargo transportation and in order not to worry about a child or a pet and track their location on specialized sites or by points sent to a mobile number.
Necessary
GPS tracker, mobile phone, personal computer
Instructions
Step 1
GPS tracker operation is simple and complex at the same time. The technology itself for the user of the device looks very simple: a small device that can be put in a car, given to a child or hung on a dog's collar, receives data from Earth satellites about the location using a GPS receiver, then sends this data to a specialized website on the Internet, as well as to the tracker owner's mobile phone. The owner can track the entire path along the map on the site online from any device (tablet, personal computer or phone).
Step 2
Technically, everything is a little more complicated. The tracker cannot work without a SIM card preinstalled in it, which via GPRS (mobile Internet) will send information about points of location on the map to your cell phone and to specialized sites. Thanks to the track created on the site, you can not only determine the location of the device, but also trace the entire path (for example, in this way you can find out if the child is skipping school). The function of saving the route is also necessary for people involved in cargo transportation to track valuable goods along the way.
Step 3
In cases where there is no way to catch GPS signals (high clouds, rain, closed room), trackers are connected to GSM networks. This gives a more pronounced error in finding the tracker, but it is calculated as only 100-150 meters.
Step 4
When deviating from the route, the owner of the tracker can enable the function of listening to sounds around the tracker. The microphone is not very strong, so you can only hear what is happening very close to the device, but sometimes this is very reassuring for parents who are worried about their children. In addition, the GPS tracker can also perform the "SOS button" functions. It is extremely convenient for communication in cases where it is not possible to use a mobile phone. The required phone number is hammered into the tracker's memory in advance, then it is enough to press just one button. In addition, you can add 2-3 more numbers to be able to use the tracker as a spare mobile phone.
Step 5
Most GPS trackers run on batteries, so don't forget to recharge the latter. The more often the signal from the device is sent, the faster the battery charge will drain. Also, the battery is planted by the use of additional functions: a vibration and fall sensor, an alarm button and listening to background sounds.
