Explore the development and advantages and disadvantages of automotive GPS navigation

And TomTom's navigation only supports Android systems and iPhones, but It provides more functions, such as displaying global traffic congestion, providing real-time road condition information and voice navigation and other functions.

Technically: from the existing GPS and Beidou navigation positioning technology to more accurate and advanced space navigation technology, as well as quantum navigation technology that may appear in the future to meet the positioning needs of more application scenarios.

The disadvantages of GPS guidance mainly include the following aspects: Affected by environmental factors: GPS receivers need to receive satellite signals in the open sky. If blocked by buildings, mountains, trees and other obstacles, it will affect the positioning accuracy.

It can be seen that the function of the satellite part of the GPS navigation system is to constantly send navigation telegrams.

How to turn on the car navigation

Open the door on this side of the car cab. Step on the brake pedal of the car to prepare to start the engine.Press the one-button start button of the car to start the engine and idle. The instrument of the car lights up, which proves that the whole car has been powered on. Click the switch to start the navigation under the central console of the car.

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.

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.

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

What operating systems does car navigation include

navigation systems include: car electronic navigation system. Automotive electronic navigation system is a new technology developed on the basis of global satellite positioning system (GPS).

The in-vehicle navigation system is mainly composed of a host, a display, an operation keyboard (remote control) and an antenna. It realizes the digital intelligent navigation of field exploration and travel. It has accurate maps, geographical information and clear routes.

In summary, aIn the hardware system architecture of on-board GPS, the main units include antenna, RF front-end, base frequency/correlator, processor core, in addition to memory and bus interface.

Driving information system Driving information system provides drivers with various forms of navigation information that is conducive to deciding how to reach the destination, ranging from the smallest direction information to the straight line distance from the destination based on real-time step-by-step route guidance instructions.

WinCE is an embedded real-time operating system provided by Microsoft. Compared with ordinary operating systems, it is more streamlined and suitable for use in embedded devices. The WinCE operating system includes the general operating system and the dedicated operating system. The conversion operating system has Po used in PDA. cketPC and smarkphone used in mobile phones.

The current mainstream of the car computer operating system is Android, which is the development direction. However, there is still a considerable share of the winCE system in the market and user base. The playback software of Android system can play high-quality music, while most of the playback software of CE system can only play mp3 music. So pay attention when buying.

What is the use of the car GPS navigation system

1. GPS navigation can provide road conditions, congestion information, etc. in real time to help drivers avoid congested sections, thus saving time and fuel. The shortest path to the destination can also be calculated according to the actual speed of the vehicle, so that the driver can reach the destination faster.

2. Navigation function Three-dimensional navigation is not only the primary function of GPS, but also its basic function.Airplanes, ships, ground vehicles and pedestrians can navigate with navigators.

3. It is a satellite navigation system that can provide global positioning, navigation and time synchronization services through a set of satellite signals. The GPS system consists of a group of 24 satellites that orbit the Earth in a specific orbit and communicate with receivers on the ground.

4. GPS (Global Positioning System) is a global, all-weather, continuous real-time, automated and high-efficiency navigation, positioning, speed measurement system launched in the United States in the early 1970s, which can be used Households provide high-precision seven-dimensional information (three-dimensional location, three-dimensional speed, time).

5. Cars equipped with GPS can use GPS for navigation. The driver enters the destination into the car's navigator. The GPS system will calculate the itinerary and plan the appropriate route according to the built-in electronic map. In the process of driving, the driver can be assisted in real time through voice and image. Driver.

6. Providing travel route planning is an important auxiliary function of the car navigation system, which includes automatic route planning and manual route design.

How to upgrade the in-vehicle navigation system?

A navigation update method is to update the on-board navigation system by updating the navigation system and map in the memory card of the loading navigation system. Another way to update navigation is to go to the 4S store, which provides the original upgrade software to upgrade the navigation system and map.

Original car navigation If the car navigation comes with the original factory, you can only go to the 4S store for upgrade. Self-installed navigation If the navigation is self-installed, it can be downloaded from the official website of the brand of the navigation through the SD card on the navigation host.

Two ways to update: If the vehicle system is equipped with the Internet of Vehicles function, you can directly update the system in the navigation vehicle to update the vehicle navigation system. You can remove the navigation and memory card of the vehicle, and update the updated data through the official download of the navigation system.

Download the upgrade file. Generally, enter the official website of the car navigation and select your navigation model to download. Generally, it is mainly in .exe format, and some files are also in .zip or .rar format. It is recommended to select the exe file, and then download the file to a local folder to prepare for update. Prepare to update tools and data cables.

What kinds of navigation systems

1. At present, there are four global navigation systems in the worldThe systems are GPS, Beidou, Galileo, GLONASS, and two regional navigation systems, IRNSS and QZSS.

2. The names of the four major navigation systems are: American Global Positioning System (GPS), Russian Glonas System, European Galileo System, and China's Beidou System. The BeiDou satellite navigation system is a global satellite navigation system developed by China, covering the world's independent geographical and spatial positioning satellite system.

3. The navigation system is: automotive electronic navigation system. Automotive electronic navigation system is a new technology developed on the basis of global satellite positioning system (GPS).

4. What are the types of navigation systems? Common GPS navigation systems are generally divided into five forms: mobile phone, PDA, multimedia, vehicle and notebook.With the popularity of smartphones and the mobile phoneization of PDA functions, the first three forms began to cross.

5. The four major satellite navigation systems are: the Global Positioning System (GPS) of the United States, the Russian "Glonus" system, the "Galileo" system of Europe, and the "Beidou" system of China.

6. The operating system of in-car navigation determines its stability and fluency. The common main operating systems on the market include Android and Windows CE. Car navigation is also known as "car navigation" and "car navigation". It is a kind of navigation device on the car.
