GPS knows where I am

GPS is an abbreviation for Global Positioning System, which translates as “global positioning system,” that is, determining the latitude and longitude of an object. To ensure the functioning of GPS, 24 special satellites, divided into six orbits, orbit the Earth. The satellites are located in such a way that signals from six of them can be received simultaneously anywhere in the world.

GPS is actively used in aviation, marine navigation, geodesy, there are also car navigators and so on, but now we are more interested in what exactly GPS can give to the average user.
If you, an ordinary user, have a GPS receiver, then, having tuned in to the appropriate satellites, it can measure and display your coordinates with very high accuracy. Moreover, as you move, these coordinates are read and issued constantly, so you can clearly track all your movements.

What is this for? In order to answer the nagging question: “Where am I?”, and also tell you how to get to the address you need, and the shortest and most pleasant way.

Until recently, global positioning systems were quite weighty devices that could not be used in everyday life. Now GPS has been significantly miniaturized, and they are even built into watches - this is what high-tech has come to. However, using a navigator on a watch is not very convenient, so modern GPS modules come in several types.

The first type is a separate positioning device that can be connected wirelessly to a regular computer: handheld, laptop. Most often, of course, such external modules are used with handheld devices - due to mobility.

The second type is a GPS device built into a regular handheld device. Well, the third type is a specialized mini-computer with built-in GPS, which is intended exclusively for navigation. Specialized mini-computers with built-in GPS are usually used by car drivers, but, in my opinion, they are noticeably less convenient than a normal handheld computer (PDA) with built-in or external GPS. However, this is all a matter of taste.
