What is the working principle of car navigation

1. The navigator can only display the specific location on the display screen by comparing it with the map in the memory card. The position coordinates determined by the GPS satellite signal will match the electronic map stored in the on-board navigator, so as to determine the exact location of the car in the electronic map, which is commonly known as the positioning function.

2. Geomagnetic direction sensors, gyro sensors, speed sensors, etc. installed on cars are used to determine the trajectory of cars.

3. The working principle of the car navigation system: detect the specifics of the car on the earth through the signal sent by the navigator and the satellite in the sky, and then feedback it back to the navigator. The specific location is displayed on the monitor by comparing it with the map in the memory card.

4. Connect to the satellite in the sky through the signal sent by the navigator, detect your specifics on the earth and then feedback to your navigator. The navigator can only show the specific location on the monitor by comparing it with the map in the memory card.

5. The basic principle of GPS navigation is to determine the position of the point to be measured according to the instantaneous position of the high-speed satellite as the known starting data, and to adopt the method of spatial distance rear intersection.

How to use navigation

1. Turn on the navigation switch button. After opening, the menu bar button of the initial interface menu will be displayed. Click the "Navigation Bar" button in the menu bar to enter the navigation interface. Determine your location according to GPS (satellite positioning), and now you can search for the destination you need to reach.

2. The specific method is as follows: First, open the car navigator to enter the main page, and click "Find Destination". Then enter the destination, as shown in the figure below. Then find the "Set Destination" option and click it to navigate.

3. Open the Gaode map and click the driving option.Enter the starting point and the arrival point. Then click the navigation.

4. When the navigator is turned on, the navigation starts until the car starts. When the device has not found the satellite, the coordinates will stay at the last place where the GPS satellite was obtained. We click to search directly. There are three main ways to input: handwriting, pinyin, and initials. In fact, the first letter is the best.

5. Tips for using car navigation. A trend of electronic products is that the operation is getting simpler and simpler, and a few buttons can complete the settings you want. However, simple operation does not mean that you can treat it carelessly. A little bit of use and maintenance can greatly extend the life of the navigation.

How to use the navigation on the car

1. First, open the car navigator to enter the main page and click "Find Destination".Then enter the destination, as shown in the figure below. Then find the "Set Destination" option and click it to navigate.

2. The steps to use a car navigator are roughly as follows (generally touch screen): turn on the navigation switch button (generally on the far left, the circle and the button of the vertical line). After opening, the initial interface (generally the radio station first) will be displayed, and then click the menu bar button in the interface (generally at the bottom left).

3. When the navigator is turned on, the car starts to start the navigation. When the device has not found the satellite, the coordinates will stay at the last place where the GPS satellite was obtained. We click to search directly. There are three main ways to input: handwriting, pinyin, and initials. In fact, the first letter is the best.

4. CarHow to use the navigation above? Get the navigation device. First of all, you need to get a navigation device, which can be a navigation system installed on the car, a handheld navigation device or a mobile phone navigation software. If you use mobile phone navigation software, you need to install and turn on the GPS positioning function.

What is a car navigation system?

1. On-board navigation is carried out using on-board GPS (Global Positioning System) with electronic maps. It can conveniently and accurately tell the driver the shortest or fastest route to the destination, which is a good helper for the driver. Synchronous satellites on Earth were originally used for military and aerial navigation.

2. The vehicle navigation system integrates technologies in automobile, transportation, computer, communication, system science and other fields.The early navigation system mainly used inertial navigation equipment, such as gyros, combses, etc. to locate the direction of the vehicle and estimate the navigation position. Due to its limited use, it has not been widely used.

3. The automotive electronic navigation system is a new technology developed on the basis of the global satellite positioning system (GPS). Its principle GPS is a device that can receive positioning satellite signals, calculate the exact longitude and latitude of the car, as well as the speed and direction of the car through the microprocessor, and display it on the monitor.

4. The vehicle navigation system includes satellite global positioning system (GPS, BeiDou), wireless receiver, various sensors, navigation control unit, map matcher, CD-ROM driver, color liquid display, corresponding software, etc. That monitor is usually in the middle of the dashboard.
