The GPS module is a radio receiver that is designed to determine the geographical coordinates of the location of the receiving antenna at the current time based on the data of the time delays in the arrival of radio signals.
Many people often confuse concepts such as GPS and GPRS. GPRS technology is designed to access the mobile Internet, GPS technology (Global Positioning System) means a satellite navigation system. The GPS receiving module does not transmit anything, it only receives data from satellites and determines its location due to the solution of a mathematical problem. In order for the device to be able to determine its location (coordinates), it is required that the device sees at least four satellites. The coordinates will be more accurate the more satellites the GPS module sees. The receiver sensitivity and speed are determined by the chip used in the device. Under the speed understand how quickly the device is able to determine the coordinates. By sensitivity is meant the ability of the receiver to determine the maximum number of satellites.
GPS-navigators can be divided into two types: professional, which have high accuracy in determining coordinates, and household. The former found application in the military sphere, in geodesy, cartography, and household ones can be found in almost any area of modern life. Professional devices are notable for the high quality of manufacturing not only components, but also antennas, software, operating frequencies, increased energy reserves, and most importantly - the price.
What is the GPS module for? First of all, these devices can be useful to motorists. After all, even in your hometown you do not always know how you can get to one place or another. GPS devices help not only get to a given street, but also accurately determine the desired house number. Also, these devices can lay the optimal route to the specified address, avoiding traffic jams and roads with oncoming one-way traffic, as well as streets and emergency sections closed for repair. Indispensable GPS-navigator for traveling to unfamiliar places. It will help you quickly get to any city you specify and any address.
However, do not think that these devices are only needed by motorists. It can be indispensable for pedestrians, especially tourists. So, the GPS module for a tablet or mobile phone can help a traveler navigate in a foreign city, find any sights, shops, markets and the like, and most importantly - will help to return back to the hotel. And you don’t have to, without knowing the language, pester passers-by so that they show you the right path.
Many outdoor enthusiasts, such as hunters, mushroom pickers, anglers, often use GPS-navigators: they help get out of any slum and return to civilization again.
Also, such a device helps to find stolen equipment. For example, a GPS module for a laptop can help determine the location of your device, which greatly helps in the search for stolen items.
