With the popularity of private cars and the increase in travel modes such as self-driving tours, car navigators have become more and more popular with car owners, and have even become a necessary "weapon" for some people to travel. Many car owners feel that it is safe to travel with it, especially when traveling far. Especially now, as the Internet of Vehicles is used more and more in our lives, navigation has become more convenient and caring.
This is not just knowing where you are going, but telling you where you are going when you are away, and what you should know, such as whether you are speeding, it will tell you in time that you will slow down to ensure their own Be safe and avoid violating traffic laws at the same time.
What historical changes have taken place in the development of car navigation systems so far? The following small series will be shared with you based on the timeline.
From the scrolling map in 1921 to the navigation of unmanned autonomous vehicles in China today, the development of navigation information systems has taken students for nearly a century.
In fact, at the beginning of car navigation, navigation is just based on the map.
People find that scrolling the map on the wrist is not as convenient as putting it on the dashboard. Therefore, Daly released a navigation system called "Iter-Auto", which can be integrated into the car dashboard to form a scrolling map. The system is also equipped with car connection lines to automatically display the local map while driving.
This is a year full of historical significance. The United States successfully launched the world's first orbital navigation satellite system, named "1B transit". In the next few years, other transportation satellites appeared one after another.
The system was put into use in 1964. The solar array is used to receive radio signals and provide navigation support for the Apple Navy’s polar submarines. It can help the spacecraft to determine the current position, relying on the satellites above the spacecraft, but the number of satellites at that time, the signal often disappears.
That year, the National General Motors Research Office moved the navigation information system into the car, and developed a navigation aid management system for students that does not rely on Chinese satellites, called "DAIR".
This kind of carrying device has its own enterprise service management center and provides two communication technology channels. It can be updated by radio signals that rely on roadside indicator lights to obtain knowledge about China's transportation network. Magnets embedded in the road can "activate" voice notifications about the next exit and current development speed limits. Drivers can choose to rely mainly on nearby route navigation stations to obtain navigation data information. At the same time, they will also need a punch card to act as a direction arrow (left, right or straight), thereby effectively helping the driver to work smoothly to reach the destination.
The US Office of Naval Research has launched the NTS-2 satellite, paving the way for the arrival of NAVSTAR GPS.
The world's first automated guided vehicle was born.
In particular, it uses a built-in helium gyroscope to detect the rotational movement of the vehicle, instead of a U.S. postal module satellite positioning device. At the same time, a special servo gear is installed in the gearbox housing to provide feedback to help maintain the position and speed of the vehicle, enabling the vehicle to display its position on a fixed map.
Etak was founded by Horney and has a navigation system with a vector map display that automatically rotates when the car turns, allowing the destination to appear on the top of the map. At the time, the company's huge database attracted a lot of attention.
To some extent, GPS satellites were only authorized in the 1980s. However, around 2000, the US government finally stopped restricting the selective use of GPS and opened up accurate global positioning data to civilian and commercial users worldwide.
With the continuous development and increase of China Mobile's smart phone system functions, companies such as TomTom can decide to develop and utilize mobile navigation technology applications. So the company launched a navigator for PDAs, and configured a base and GPS receiver to help students locate the location.
The car navigation system has developed to a certain extent, and the head-up display has naturally become the next new field to realize the development of the navigation technology market. So Pioneer launched its own NavGate system. This software system is designed to provide enterprises with a certain degree of influence of virtual social reality navigation services. A large translucent projection screen is installed on the position of the car sunshade to project the driver’s field of vision. The overlay image inside.
With the rapid development of science and technology, one-button navigation, voice-controlled navigation, car networking and mobile phone synchronization are the development directions of car navigation in the future.
