Like equipment that looks tall but doesn't need to be cleaned, such as skylights and headlights, the use of car navigation feels very bad. Not only do some car navigation screens have poor UI design, but the reaction sensitivity resembling a resistive screen is now driving people crazy. So why are car companies still very enthusiastic about using car navigation with such poor touch? The primary role of in car navigation is to assist drivers in identifying road traffic. However, with the rapid development of mobile phones, the usage rate of car phones is far less than that of mobile phones. Looking at the sales of mobile phone holders online, it can be verified that customers often rely more on mobile phones than car phones. For example, when I open a certain navigation when getting on the car, the map of the in car interconnected system is not only slow to update but also messy to operate, resulting in poor user experience. For this point, some car companies can say that they have a very thorough understanding of customers' thoughts, considering mobile phone holders for customers at the original factory. Although low-end models are not equipped with car navigation, they are equipped with "humanized" mobile phone holders for customers. This difference in product concavity and concavity is not excessive, after all, car machines are not produced by car companies, and purchased car machines have cost control. So the primary reason why car companies are still enthusiastic about such a weak car engine is that it can become additional capital to enhance the selling point of the product, and then achieve higher prices and profits. Car mechanics has now become one of the fields of research and expansion for car companies. How to make car mechanics more user-friendly, intelligent, and networked, and use car mechanics to assist in driving, has become one of the current development directions. For example, Windlink in Spring Breeze and Zebra Zhixing in SAIC are all research achievements in this field. In the future, car mechanics will not only be used for navigation, but also be more networked and intelligent. In addition to assisting in driving and improving product profitability, another important role of car mechanics is to "look at the atmosphere". In this society where I have you or not, car mechanics have become one of the goals for customers to compare with each other. Just like the small blackboard work of the KX7 back then, when others are equipped with larger and more technological central control screens, while the KX7 uses such a cheap small blackboard, it inevitably depreciates the price In fact, car navigation is quite challenging now, and its ease of use is far less convenient than that of a mobile phone. However, in the future, it will not only be a car navigation, but also an intelligent assistant that can assist drivers in completing more tasks. In this context, car navigation can also improve the visual perception of the interior, and can also increase the profitability and price of the entire vehicle to another level.

1. The chip of the satellite signal receiving module. This is an important component that determines the accuracy and speed of GPS. Choosing a outdated chip means that when your car reaches an intersection, you need to wait for GPS to tell you how to go before you can drive. If you walk at normal speed, you will occasionally have to return to the original route and correct errors. Currently, the first to third generation chips on the market are in use, and most dealers do not tell you the chip performance of their products when selling GPS. It's like when you buy a phone, people won't tell you how much CPU the phone has, because once they tell you that the CPU version of the phone is very low, it will affect its usage speed. Would you still buy this phone? (I use a certain brand of GPS navigator, and at every intersection from Shenzhen to Zhuhai, the GPS response speed and driving speed will differ by a few seconds to more than ten seconds, making the driving experience very uncomfortable.) 2. The speed of map updates. Nowadays, the speed of construction and development in various places is very fast. If manufacturers do not provide map update services in a timely manner, your GPS will not have much use. Of course, GPS sales personnel will not proactively tell you about this. The salesperson will tell you how many places and towns can be covered by the maps installed in its GPS. But if you think about it, if the map is not updated, it won't be long before your GPS displays a map that is very different from the actual one. (I used another brand of GPS navigator to travel 160 kilometers from Fuxin City to Changchun City. The reason is that the Tiechao Expressway has been open for 10 months and there is only 380 kilometers between the two places. However, the GPS navigator still instructed me to take the old road of Shenha Expressway, which is 540 kilometers between the two places.) 3. Provide a time for free updates. Generally, GPS produced by informal enterprises uses cracked maps and does not provide update services. Some companies still use genuine maps but do not provide update services. Some companies also use genuine maps, but there is an additional fee for map updates. Some companies also provide you with long-term free map updates. You should know that the price ratio of the common GPS navigator hardware itself in the market to the price of genuine map software is about 1:3 or 1:6, which means that the hardware is cheaper than the software. So, when choosing a GPS navigator, you need to look at both hardware and software. Otherwise, the GPS you have in hand is a useless piece of junk.

Introduction to Car Radio - Principles GPS is composed of three major components: space satellites, ground monitoring, and user reception. In space, there are 24 satellites forming a distribution network, each located in 6 Earth's quasi synchronous orbits with a tilt angle of 55 ° and a distance of 20000 kilometers from the ground. There are 4 satellites in each orbit. GPS satellites orbit the Earth every 12 hours, enabling any location on the Earth to simultaneously receive signals from 7-9 satellites. There is a total of 1 main control station and 5 monitoring stations on the ground responsible for monitoring, telemetry, tracking, and control of satellites. They are responsible for observing each satellite and providing observation data to the main control station. After receiving the data, the main control station calculates the accurate position of each satellite at each moment and transmits it to the satellite through three injection stations. The satellite then transmits this data to the ground through radio waves to the user's receiving device. Only after more than 20 years of research and experiments on the GPS system and a cost of 30 billion US dollars, the 24 GPS satellite constellation with a world coverage rate of 98% were officially deployed in March 1994. Now the application of GPS system is not limited to the military field, but has developed into various fields such as vehicle navigation, atmospheric observation, geographical survey, ocean rescue, manned spacecraft protection and detection. Introduction to Automotive Navigator - Composition The operation of the GPS navigator also requires a car navigation system. Having a GPS system alone is not enough. It can only receive data sent by GPS satellites, calculate users' three-dimensional position, direction, and motion speed and time information, and has no path calculation ability. In order for the GPS receiving device in the user's hands to achieve route navigation function, a complete car navigation system including hardware devices, electronic maps, and navigation software is also needed. The hardware of the GPS navigator includes components such as chips, antennas, processors, memory, screens, buttons, speakers, etc. However, as of now, there is not much difference in hardware between GPS car navigators in the market, and it is difficult to distinguish who is good from who is bad with built-in software maps. Currently, there are eight mapping companies in China engaged in the surveying and development of navigation map software, such as 4D Tuxin, Kailide, Daodao Tong, Chengjitong, After several years of continuous development and improvement, we have been able to provide quite good navigation map software. To summarize, a complete GPS car navigator consists of nine main components: a chip, antenna, processor, memory, display screen, speakers, buttons, expansion function slots, and map navigation software.
