What is the most widely used navigation system in my country at present?

Currently the most widely used navigation system in our country is GPS. The GPS navigation system is a radio navigation and positioning system based on 24 positioning satellites around the world that provides three-dimensional position, three-dimensional speed and other information to all parts of the world around the clock.

Currently the most widely used navigation system in our country is GPS.

The GPS navigation system is a radio navigation and positioning system based on 24 positioning satellites around the world that provides three-dimensional position, three-dimensional speed and other information to all parts of the world around the clock. It consists of three parts. The first is the ground control part, which consists of the main control station, ground antenna, monitoring station and communication auxiliary system. The second is the space part, which consists of 24 satellites distributed in 6 orbital planes. The third is the user device part, which consists of a GPS receiver and a satellite antenna. Civilian positioning accuracy can reach within 10 meters.

System functions

The GPS navigation system was initially established for military purposes, and later slowly developed for civilian use. The GPS navigation system is a radio navigation and positioning system that provides drivers with three-dimensional position, three-dimensional speed and other information around the clock through artificial satellites.

The vehicle-mounted GPS navigation system, its built-in GPS antenna will receive data information from at least 3 of the 24 GPS satellites orbiting the earth, combined with the electronic map stored in the vehicle-mounted navigation system, through The position coordinates determined by the GPS satellite signal match this to determine the exact position of the car in the electronic map. This is what is commonly known as the positioning function.

Based on the positioning, the best driving route, road conditions ahead, and the nearest gas station, restaurant, hotel and other information can be provided through the multi-function display. If unfortunately the GPS signal is interrupted and you lose your way, don't worry, the GPS has recorded your driving route, and you can return the same way. Of course, these functions are inseparable from the map software that has been compiled in advance for the use area.

Another great function of vehicle-mounted GPS is anti-theft, which is divided into two types: static anti-theft and dynamic tracking. The former means that when the car owner leaves the car and the parked vehicle is stolen, damaged, or moved, the vehicle sends an alarm to the GPS monitoring center through its own monitoring system, and automatically contacts the owner's mobile phone, calls the police, etc. The latter can locate and track stolen vehicles in motion, monitor vehicle conditions, record vehicle tracks, and even control vehicle power and fuel cuts, etc.
