1, Beidou civil chip. According to the official website of Jiuzhou Xingyi Company, the Beidou No. 3 navigation and communication chip is a Beidou civil chip developed by Jiuzhou Xingyi Company. It has the GNSS system full frequency point high-precision navigation and positioning function, and can realize regional and global short message communication.
2The third-generation Beidou chip is used in the construction of the Beidou 3 satellite system, which can achieve sub-meter level positioning accuracy and achieve chip-level security encryption without foundation enhancement. On September 16, "the world's first multi-system multi-frequency high-precision SoC chip supporting the new generation of Beidou-3 signal system" was officially released.
3, the decoding chip is done from the compressed file to the audio format to show that it is the reverse process of compression (or coding). A good decoding chip (or the player on your computer) can better restore the audio information before compression, which can make up for the audio signal pressure to a large extentShrinkage process loss.
chip is a French fry, potato chip, chip, chip, notch, or chip. The plural form of chip is chips, the third person singular is chips, the past tense is chipped, the past participle is chipped, and the present participle is chipping.
Biochip is a micro-laboratory with multiple micro-reaction chambers, which can be used to achieve multiple generation in a sample958% equity. Bda Beidou focuses on the research and development and design of Beidou chips, and released the world's first multi-system, multi-frequency, high-precision SOC chip supporting the new generation of Beidou III signal system, as well as the "first domestic dual-frequency Beidou chip" in the era of ultra-precise positioning.
2, At present, Unigroup Group, Huawei hisilicon two companies in many fields have been the world's leading level, but a huge problem is that the core of their architecture authorization is controlled by outsiders. 3, Recently, China Beidou spokesman Ran Chengqi solemnly announced at the press conference of the State New Office that the Beidou system 28nm process chipAlready in mass production, the 22nm process chip is about to be mass-produced, leading the US GPS process for two generations.
4, BeidouStarcom 002151 navigation high-precision application products continued last year's good momentum, driving rapid growth of operating revenue.
2, the chip does not need to be charged, but the device needs to provide power to use, at present, all chips need power to achieve. Low power consumption is achieved by using bioelectricity, there are also battery-powered micro-batteries, and there are direct power supply lines. The chip itself does not store electricity.
3, but it still needs some power supply to maintain its internal state and stored data. Therefore, in general, in order for the chip to function and perform the function for which it is designed, it needs to be provided with the appropriate power supply voltage. Only in the chip connectionIt can only work as designed if it is connected to the power supply and powered correctly.
4, satellite power supply system, also known as energy system or power supply and distribution system Beidou satellite also has its own energy power supply and distribution system. Energy systems generally include solar arrays, battery packs, power controllers, equalizers and distributors. The internal and external relations are as follows: the solar array is the power generation unit and the main power supply energy.
The real "China core", the chief designer of the Beidou system: beyond GPS, more powerful, more accurate At present, Beidou is the first in the world to create three hybrid orbital constellations. Compared with other systems, Beidou has added new functions such as accurate single point positioning, satellite-based enhancement, regional and global short message communication, and international search and rescue.
The first two generations of Beidou satellite chips rely on imports from the United States, but the third generation has been fully replaced by domestic chips. Why is the chip the core of all high-tech products? It's not just in our phones, computers, etcIn electronic products, the Beidou navigation satellite is the best example.
Second, foreign GPS baseband chip technology has developed to the fourth generation, accumulated a lot of practical experience in anti-multipath, inertial navigation, chip technology has been very mature, to achieve a single chip program, the cost advantage is very obvious. These experiences are accumulated through a lot of testing and actual operation of the system.
The GPS used in the phone is American. In 2020, there are four global satellite navigation systems in the world, in addition to China's Beidou, there are the United States GPS, Russia's Glonass, and Europe's Galileo". The most mature is still the US GPS system.
China Haida "Global precision" system HI has been officially released to the world -RTP, Beidou high-precision navigation chip "Stellar No. 1" and the first fully independent technology GNSS dish antenna put into practical application in China. Jinjia Co., LTD. (002191) holds HuaGreat Beidou 7,958% of the equity.
The chips produced in China are Loongxin series, Sunway series, Feiteng series, VIA series, Sunway series. The Loongson series general processor is a general processor developed by our country, which is of great significance to the maintenance of information security in our country.
