Curious what does gps mean? it's actually really easy. It's the Global Positioning System. To put it bluntly, it is a positioning system that can know your current position, speed, etc. Anytime, anywhere. While you might think it's amazing, the technology is now beyond your imagination. Satellites are like God watching you all the time. It doesn't affect your life, but it always knows what you're doing.

　　1. gps is global positioning system

　　Now many devices have gps function, so what is gps? In fact, its full name is GlobalPositioningSystem, which is translated into Chinese as "Global Positioning System", which originally originated from a project of the US military. Although the global positioning system in the United States is widely used now, in fact, some countries already have their own GPS.

　　Such as Russia's Global Positioning System (GLONASS), China's Beidou Navigation System (BDS), Europe's Galileo and so on. , all of which can be called GPS, not the US Global Positioning System. However, all of them can provide information such as three-dimensional position, three-dimensional velocity, etc. to all parts of the world through artificial satellites.

　　2. GPS is mainly composed of three parts

　　1. The ground control part consists of the main control station, ground antenna, monitoring station and communication auxiliary system.

　　2. The space segment consists of 24 satellites distributed in 6 orbital planes.

　　3. The user equipment part is composed of gps receiver and satellite antenna, and now the civil positioning accuracy can reach within 10m.

　　Third, the function of car gps

　　1. Navigation function

　　If the driver selects the start and end point of the driving route on the vehicle's gps navigation system, the navigation system will provide you with the best driving route based on your current location and traffic conditions.

　　2. Electronic map

　　Covering the information of major domestic cities and local roads, it can even display the traffic situation of the destination city at any time.

　　3. Go to the voice prompt function.

　　If you encounter an intersection or turn ahead, the system will give a voice reminder in advance.

　　4. Positioning function

　　GPS can accurately locate its own position by receiving satellite signals, and the error is within 10m.

　　5. Anti-theft function

　　There are two anti-theft functions: static anti-theft and dynamic tracking. Static anti-theft means that when you leave the car and the parked car is stolen, destroyed or moved, the car will send an alarm to the gps monitoring center through its own monitoring system, and automatically contact the owner's mobile phone or telephone for alarm, etc. Dynamic tracking means that it can locate and track stolen vehicles while driving, monitor vehicle conditions, record tracks, and even cut off the vehicle's power supply and oil circuit, with many functions.
