What is navigation used for, and what are the functions of car navigation?

The role of subnavigation:

1. Give a deeper page entry.

Some pages with a deeper hierarchy or the first page of the column do not have an entrance, you can choose to put the more important ones in the secondary navigation to give the entrance, which is convenient for search engine spiders to crawl and reduce the number of isolated pages.

2. Pass weights where they are useful.

We can choose the more important content to put on the secondary navigation and add accurate keywords, which can convey higher weight and increase the relevance of the recommended inner pages, and the content in the general secondary navigation is easier to rank.

3. Provide users with a variety of choices.

When the user enters the home page, it may take multiple clicks to reach the desired page, so the sub-navigation can provide users with a variety of choices, reduce the user's click cost to improve the user experience.

1. It is convenient to access the Internet, 2. It is simple and clear.

The main purpose is positioning, monitoring and navigation. Due to the wide range of civilian navigation, everyone mentions that the on-board GPS is the navigation product used in the car. That is, the on-board or portable GPS navigation system used in the car.

Urban road conditions are becoming more and more complex, and equipping a car with an accurate GPS satellite navigation device has become a new choice for many motorists. GPS is a satellite positioning system that uses satellites to locate access points to know where the access point is located.

Vehicle satellite positioning system is mainly used in the field of car navigation. To put it bluntly, it provides a convenient tool for car drivers to choose their routes. The following is an introduction to six GPS for friends who love cars, and I believe it will give you some help.

The focus of on-board GPS is GPS positioning, and the anti-theft and anti-robbery mentioned above are some value-added services provided by GPS.

GPS navigator has risen in the market in recent years, and its emergence has brought a lot of convenience to people's travel. Aside from the heavy map, the driver only needs to enter the destination into the car navigation system, and the system will automatically calculate the most suitable route according to the built-in electronic map, and remind the driver to pay attention to the itinerary at any time while the vehicle is moving.

During the entire journey, the driver does not have to think about the route at all, and even in a completely unfamiliar city, the navigator will automatically guide the driver to the intended destination.

Although GPS navigator has attracted more and more attention from car owners because of its professionalism and convenience, there are still many consumers who are not clear about the concept of GPS navigator, so let's first open a literacy ** to fully popularize the knowledge of GPS navigators.

In the 15th century, the great scientist Leonardo da Vinci conceived a self-driving vehicle and left behind a blueprint. It's a clockwork-powered vehicle. In 1649, the German watchmaker Hans Herchu successfully prototyped a prototype based on the blueprints, which reached a speed of kilometers per hour.

Due to military needs, Urcolas Joseph Ciuniyo (1725-1804), an army artillery captain under Louis XIV of France, was ordered to develop a power tractor to tow cannons. In 1769, he made the No. 1 car at the Paris Arsenal, but it could not be driven and the trial production failed; In May 1771, the No. 2 car, which was larger than the No. 1 car, was not ideal, but it could seat four people and reach a speed of up to kilometers per hour, becoming the first vehicle in history to use steam power without relying on external forces such as wind and animal power. It is a wooden tricycle with a length and width.

A large boiler of cubic meters is suspended on a special frame in front of the front wheels, and the steam generated is sent to the cylinders that hang vertically above the front wheels, driving two pistons to rotate the front wheels, becoming the first "automatic car" in history.

Because the boiler and the two cylinders are installed in the front and upper parts of the front wheels that shake during driving, the driving is unstable, and there is no condenser, so you have to stop every 15 minutes to add water, which is very inconvenient, and there is no braking, it is very dangerous, and the result is that it crashes into the city wall and causes an accident in a test drive. In 1789, Napoleon I ordered the restoration of the car, and in 1801 it was sent to the Musée National des Arts et Métiers in Paris for safekeeping.

Since then, there has been a constant search to improve the performance and appearance of the car. More than 50 years later, in 1826, Blanc successfully built the world's first real internal combustion engine car in England, and was granted patent No. 5350 on April 25 of the same year. This two-cylinder car, with good performance, can not only run on flat avenues, but also climb steep slopes.

In May 1826, it successfully climbed Mount Hunter in Blacks, Kent, England.

The main function of car navigation is navigation, and secondly, there are many entertainment functions, you can go to the affordable ** online to take a look.

The built-in GPS antenna of the in-vehicle GPS navigation system will receive data transmitted from at least 3 of the 24 GPS satellites orbiting the earth, combined with the electronic map stored in the car navigation system.

The position coordinates determined by GPS satellite signals match this to determine the exact position of the car in the electronic map.

This is commonly referred to as the positioning function. On the basis of positioning, it is possible to use a multi-function viewer.

Provide information on the best driving routes, road conditions ahead, and the nearest gas stations, restaurants, hotels, etc. If you get lost due to the GPS signal being interrupted, don't worry, the GPS has recorded your driving route and you can go back the way you came. Of course, these functions are inseparable from the mapping software of the area that has been prepared in advance.

Car GPS also has a big function is anti-theft, which is divided into two types: static anti-theft and dynamic tracking. The former refers to the owner leaving the car, when the parked vehicle is stolen, destroyed, and moved, the vehicle sends an alarm to the GPS monitoring center through its own monitoring system, and automatically contacts the owner's mobile phone, alarm, etc. The latter can locate and track the stolen vehicles in operation, monitor vehicle conditions, record vehicle tracks, and even control vehicle power and fuel cuts.

Name implies. Navigation means giving you directions. The navigation function is generally a function that comes with mobile phones.

Turn on navigation. You can go to places you don't know. She can guide you in the right direction.

It is an essential function of the phone. It is also a weapon in daily life.

The navigation function is to plan the target and local route through satellite positioning, and you can go to unfamiliar places through navigation.

That is to say, the electronic map function, which is the orthodox function of GPS. As soon as the owner enters the start and end points, the system will immediately point the best shortcut between the two places to the owner. Unfortunately, this technology is still a concept in China for a short time.

It is said that China's FAW and other companies have begun to develop autonomous navigation systems, so car owners have reason to believe that GPS navigation can play a role in the near future.

At present, the country is mainly through voice navigation, the owner can get the location of the vehicle through the vehicle's monitoring center, and can also query the walking route to the center. This kind of voice navigation is not perfect compared with foreign electronic maps, but it can reduce the pressure of the car owner to read the map while driving, and the car owner can easily get guidance as long as it is hands-free**.

Navigation is mainly about monitoring and controlling the movement of a process or vehicle from one place to another.

1. Map inquiry.

Search for the location of the destination you want to go to on the operation terminal, record the location information of the place you often go to, and keep it, and you can also share the location information with others, and query the information near a certain location, such as gas stations, hotels, ATMs, etc.

2. Route planning.

The GPS navigation system will automatically plan a route based on the starting point and destination you set. Planning routes can be set whether or not they want to pass through certain waypoints. The planning route can be set whether to avoid high-speed and other functions.

3. Electronic dog function.

There are speed measurement information points at intersections in the GPS map, and GPS will remind you by voice. If there is no information point in the map to measure the speed, it will not be reminded. Therefore, it is not possible to rely solely on GPS to reverse speed test.

Navigation is used to guide the navigation of vehicles, airplanes or ships, or the movement of people.

Navigation devices include navigation signs, radars, and radio guidance devices, and the early radio guidance and radar navigation were mainly used for military navigation and bombing of aircraft, ships, and ships.

Civil navigation in the 90s was mainly car navigation. In the past decade, with the advent of smart phones, the large coverage of navigation satellites. Mobile map navigation has become the navigation of the general public.
