Three stages of the operating principle of the GPS system

GPS is a satellite-based system that works in all weather conditions to provide position details. It is used to locate goods by air, land or sea and minimize the potential risk of theft. GPS trackers have different designs, other trackers like hidden GPS trackers don't need to be hardwired; So they can be placed anywhere as long as there is a communication network. In this article, we will describe how GPS works.

How does the GPS system work?

The system is divided into three main categories: space, control and user part. Next, we will discuss how GPS determines the location of an object or a person.

1. Spatial part

It is also known as the GPS satellite, 29 of which orbit the earth every 12 hours. Only four satellites can be seen from the earth at a time, making the tracking process easier. This segment is designed to store these signals and retransmit messages sent by the Control Section using all signals involved in the selected routing.

2. Control Section

This segment is also called a monitoring station. It includes six stations, including a control station, which is superior to the other five, called monitoring stations. One of the features of this part is that it is equipped with an atomic clock which is distributed around the earth to control the transmission. The role of the five monitoring stations is to track the signals from the GPS satellites and transmit the data to the main monitoring station or the upper monitoring station. The main control system plays an important role in fault detection. During the transmission of information, errors may occur, which reduce the level of precision, so the main system modifies them and sends them to the GPS satellite through the GPS satellite. a circularly polarized antenna.

3. User part

This section is about the GPS receiver, which is the main component. The GPS satellite sends signals to the receiver which determines the distance between each signal and its originating satellite. The military mainly uses this segment, but ordinary people can also use it in applications that require GPS.

How does GPS determine location?

The GPS tracking system is based on a mathematical principle called trilateral measurement. However, we will not study the details in depth, but the position is determined based on the distance from the satellite. The receiver receives information from the satellite and determines its position by triangulation. These four satellites determine the position of the receiver on earth. Tracking of any position is done by the first three satellites, while the fourth satellite gives the exact position of the target.

GPS is one of many groups of satellites used to confirm the exact location of something. Among other functions, the system allows locating, tracking the movements of objects or people or plotting global details. The working process can be a bit scientific, but the details provided above are simple and easy to understand. Try to understand the basics of how it works or ask the seller to help you understand before buying.
