Car What does navigation mean?

The function of navigation is equivalent to a guide. In-car navigation can help drivers reach their destination with the best journey. Navigation can also provide road conditions, distance and other information. Through the navigation function, it can take you from where you are to another place you want to reach.

refers to GPS navigation. As long as the destination is set, the driving route of the car will be displayed, and there will be prompts for turning and so on. But the driver still needs to drive. With the function of GPS global satellite positioning system, you can know your exact location anytime and anywhere when driving a car.

On-board GPS navigation system, its built-in GPS antenna will receive data information transmitted by at least 3 of the 24 GPS satellites around the earth. Combined with the electronic map stored in the on-board navigator, the position coordinates determined by the GPS satellite signal match it. Determine the exact location of the car in the electronic map.

The car is completely for driving. When it is turned on, it is ready to navigate for you. All locations are regarded as the starting point or destination. The main function of the map is to provide geographic information services and take into account navigation. The main function of the car is navigation, which also takes into account geographic information services. For those who need driving navigation, of course, the car is easy to use.

Navigation is used to guide vehicle driving, aircraft or ship navigation, or human walking.Navigation devices include navigation signs, radars and radio guidance devices. In the early days, radio guidance and radar navigation were mainly used for military aircraft and ship navigation and bombing. Civil navigation in the 1990s was mainly car navigation.

What is the working principle of car navigation

1.The navigator can only display the specific location on the display 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. The basic principle of GPS navigation is based on high-speed movement.The instantaneous position of the satellite is used as a known starting data, and the spatial distance back intersection method is used to determine the position of the point to be measured.

5. 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.

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.

How to turn on the car navigation

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.

Step 1: Open the central control screen of the vehicle and find the icon of the navigation system. Step 2: Click the navigation icon to enter the navigation system menu. Step 3: In the navigation menu, select the "Destination" option.Step 4: Enter the destination address you want to go to, or select the preset location.

It is not complicated to use a car navigator. First, start the vehicle, then turn on the car display and on-board navigation function in turn, and finally set up the navigation. Next, let's learn about it with the editor.

Get navigation equipment. First of all, you need to get a navigation device, which can be a navigation system installed in 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.

Preparation before turning on the car navigation. First of all, we need to start the vehicle. Before the vehicle starts, we need to think about where we are going, estimate the approximate time, and start the vehicle. The circuit of the whole vehicle is unobstructed so that we can operate the navigation system.Turn on the car display.
