How to set the vehicle navigation system destination

How to use: All GPS can not receive satellites indoors or the signal is very weak, only outdoors can receive the signal, this is common sense The correct way to search for signals is:

Fixed search signal, do not move, because walking GPS is not easy to locate.

Open the machine to the navigation interface, click on the upper right corner of the navigation interface. signal signs, you can see the number of satellites receiving maps, normal 3 positioning, 5 navigation.

Open the upper right side of the back of the machine, the GPS accepts the satellite signal module, and the machine is at an angle of 90 degrees, and the signal acceptance effect is the best.

Speed of receiving signal: There are two concepts involved.

Cold start meaning: It is the first time GPS searches the satellite is called cold start, which is usually slow.

Different GPS satellite search speeds are different, some GPS cold start to search for satellites within 1 minute, some are 1 minute away, about 1 minute to 2 minutes, and some are 2 minutes away.

Hot start meaning: After starting within 2 hours, it is hot start, and hot start is the fastest, usually 1-2 seconds to search for satellites. 2 hours-4 hours is warm start.

Principle: The navigator is calculated by calculating the angle between the satellites, if you want to position, you must have 3 satellites, and then the navigation system calculates the angle between every 2 satellites, and calculates 3 angles, so that you can get the angle of the navigator relative to the satellite.

That depends on the navigator you use, brother

First enter the navigation system, and then click to find Brother Yukai, enter the place you want to go, first enter the province, then find the city, and then find a specific place, click to query, the map locks the location, and then set it to the destination, and then there will be a way to choose the road, high-speed or the shortest path or the least charge or system recommendation, choose one, and then navigate on the line.

Through commercial communication satellites, GPS is applied to vehicle navigation to guide car drivers, and it becomes a vehicle navigation system. On the other hand, traditional maps often fail to keep up with the changes in the streets and are difficult to read, often making it impossible for drivers to get accurate instructions. Therefore, a satellite navigation system that can use satellite signals at high altitude to accurately and timely navigate and locate the car.

Due to the accurate position of Weixian caller, in GPS observation, we can get the distance from the satellite to the receiver, using the distance formula in three-dimensional coordinates, using three satellites, we can form three equations to solve the position of the observation point (x, y, z). Considering the error between the clock of the satellite and the clock of the receiver, there are actually 4 unknowns, x, y, z and clock difference, so it is necessary to introduce the fourth satellite to form 4 equations to solve, so as to obtain the latitude and longitude and elevation of the observation point.

First enter the navigation system, Dust Lao and then click to search for Bijia, enter the destination, first enter the province, then find the city, then find the specific place of the number of liters, then click on the query, draw the location, and then set it as the destination, then there will be a route selection method, high-speed or shortest route, the least charge or system recommendation, choose one, and then navigate.

Through commercial communication satellites, the global positioning system is applied to vehicle navigation to guide motorists and become a vehicle navigation system. On the other hand, traditional maps often can't keep up with the changes in the streets, are difficult to identify, and often make it impossible for drivers to get accurate instructions. Therefore, it is a satellite navigation system that uses satellite signals at high altitude to accurately and timely navigate and locate the car.

Because the position of the satellite is accurate, we can get the distance from the satellite to the receiver in GPS observations. Using the three-dimensional coordinates and the distance formula for the three satellites, we can form three equations to calculate the location of the observation point (x, y, z). Considering the error between the satellite clock and the receiver clock, there are actually four unknowns, namely x, y, z, and clock difference.

Therefore, it is necessary to introduce a fourth satellite to form four equations to solve, so as to obtain the latitude, longitude and elevation of the observation point.

Millions of car purchase subsidies.

1. Prepare before turning on the car navigation.

First of all, we need to start the vehicle first, before the vehicle drives, think about where we want to go, estimate the approximate time, and start the vehicle, so that the circuit of the whole vehicle is unblocked, so that we can operate the navigation system.

2. Turn on the car display.

As shown in the figure, we need to turn on the display screen on the car, each model is different, but it is the same, we find the button of the switch, and then press it with your hand, because the circuit is unblocked, the screen will soon light up.

3. Turn on the car navigation function.

On the display screen of the car, we find the option of "navigation", and then click it with our hands, which is the same as the touch screen of the mobile phone, which is very convenient, so that the car navigation is turned on.

4. Set up navigation. In the lower right corner of the navigation homepage, we can see that there are all menu options, you can click with your hands, here we can see the places we often go to, such as "back to work", "go home", etc., we can set some commonly used routes, just save it, so that it is much more convenient for us to use it again.

5. Adjust the size of the map on the navigation page.

In the lower right corner of the navigation page, we can find a "+" and "-" signs, you can press and hold the "+" with your hand so that the map will continue to zoom in, and press and hold "-" The map will continue to zoom out until it reaches your ideal size.

6. The vehicle starts and the navigation starts.

Start the vehicle, as shown in the picture, the red arrow in the screen indicates the location of our vehicle, and some signs around it, which can make us familiar with the driving environment as soon as possible, and there are voice prompts to pay attention to the road section.

1.First of all, turn on the computer and click on the navigation (generally the touch screen, you can directly select to enter).

2.Then after the navigation system starts, click Find, which will enter the selection screen or open the input panel.

3.The next step is to enter the address. One way is to make a selection through a list, with provinces, cities, and counties being selected on a case-by-case basis.

4.After the final selection, enter the map, there are two small flag icons (or buttons, usually prompted), click to select and set as the destination.

Added: You can set a start location similar to this. In addition, after the setting is completed, you can simulate the navigation for preview, which is more convenient for you to drive.

Collect the big map first, for example, if you go to Quancheng Square in Jinan City, click on Shandong Province first, then, Jinan City, and then that's it, so it's good, and then there will be a choice, high-speed priority? Distance takes precedence, time preference.
