A tracker for location tracking (GPS tracker)

GPS / a-GPS entered our lives firmly and somehow amazingly fast. The cost of a simple Navigator is slightly higher than the price of a good liquid compass, a set of functions, the information content of these two navigation devices is nothing to compare. And considering that today 95 out of 100 phones are available with built-in GPS-module, the orientation of the stars, the trees and the moss on the stones will soon be about as anachronistic as the postman with a telegram in his bag.

On the other hand, unfortunately, stolen cars and other property in our country are not uncommon. Lost, unfortunately, sometimes people. For example, according to statistics, at least a few hundred people don't come back every year since “passive hunting". This is especially true of elderly people. Many unpleasant incidents could be avoided using a normal GPS tracker for location tracking.

How it works

Let us Recall a little school geometry. This will help us to understand how a bug to track the location and General positioning of the object on the Earth's surface. Suppose we have a point “X”, the location where you want to calculate. We have the following:

• Distance from the unknown point to the other three (T1, T2 and T3);
• The coordinates of these three points.

The Desired position of the point “X” to define easier: it is enough to apply to a pattern of dots with known coordinates:

• Construct a circle with center at T1 and radius equal to the distance from point T1 to point “X”;
• To do the same with points T2 and T3;
• The intersection of the constructed circle will give point “X”.

And the bug for location tracking, as well as the other GPS device, this principle finds your location on the planet's surface. Points with known coordinates-satellites navigation systems. Data about their position in space in real time receives the GPS module of the device, and for the duration of the passage from them signal, the program calculates the distance to the spacecraft.

Positioning System

A Pioneer satellite navigation system available for the mass market, is the American GPS. The first devices were placed on ships and military equipment, then gradually desheveya and improving, came to private cars and even cell phones.

Except the Americans, the satellite navigation is our country, the United Europe and of course China. And if the first civilian GPS device has worked, usually only with us satellites that produced now well - “see” and our GLONASS, and the European “Galileo”, and BeiDou developed in China.

How to use GPS tracker

GPS-tracker is a symbiosis of the two systems:

• Devices satellite positioning;
• Cell communication on the GSM platform.

Each system has its own function. GPS module real-time monitors your location and converts the received data in the geographical coordinates: latitude and longitude. Block cellular request provides these coordinates to a third-party mobile device telephone number which is previously introduced to the memory bug. For this bug to track the location provided with a slot for a SIM card.

Get the coordinates of the smartphone with the bug (such devices are called trackers) in several ways, depending on the device tracker or the preferences of the owner. Most often, the number of the SIM card bug just sent a blank TEXT, or is a “blank” call. In response to the mobile device receives an SMS with the coordinates of the beacon.

A More advanced method is the use of special mobile apps. Method is somewhat more complicated, but the location of the object can be seen immediately on an interactive map. If necessary, all the moving person or object, the media tracker, you can track online.

How to use GPS in the car bugs

A Tracker for tracking a location of a vehicle is equipped with a special antenna that allows a good to hide the device from prying eyes, but at the same time to remain visible for the satellite navigation systems. The same is not the usual lithium-ion battery, instead the tracker is connected to the onboard network of the car (or motorcycle). Mount beacon is best in such places to the hijacker or not found it or dismantling it would take too much time.

Sometimes the owners are going to this trick: set a lighthouse, which is well hidden, and “dummy” – an old non-working module, but nevertheless with the SIM card and connected to the network. Bug to track the location of a car on the phone to provide a SIM card with zero maintenance fees and expensive phone calls.

If the grandfather mushroom

Where our children

Partly to protect themselves from worrying about children also can, using the bug to track the location.

This is the opportunity for remote listening, etc. are Produced such gadgets in the form of watches, key chains and other trinkets. And the small size enables them to hide even in school clothes. However, keep in mind that the tracker – is not a panacea. And the basis of child safety-is the proper upbringing and education of safe behavior.
