On July 7th, Hexintong, a subsidiary of Beidouxingtong, released a new generation of Beidou high-precision positioning module UM982, which is based on a new generation of radio frequency baseband and high-precision algorithm integrated GNSS SoC chip independently developed by Hexinxingtong - NebulasIV design , and adopts 22nm process. This product is mainly used for high-precision navigation and positioning fields such as drones, lawn mowers, precision agriculture and intelligent driving. On-chip RTK positioning and dual-antenna orientation solution. The product has a built-in advanced anti-jamming unit, which ensures that the module can still provide reliable and accurate positioning accuracy even in complex electromagnetic environments.
In recent years, China's Beidou chip has achieved a breakthrough in the 22nm process, which is even ahead of GPS chips. However, from a traditional point of view, navigation chips do not need too advanced manufacturing processes. The manufacturing process of navigation chips on the market is generally around 40nm. Why does China's Beidou navigation chips continue to pursue more advanced manufacturing processes?
Zhang Quande, the former secretary-general of China Satellite Navigation Association, told the reporter of China Electronics News that with the comprehensive development of Beidou's "integration of technology, network, terminal, and data", "Beidou +" innovation and "Beidou + Beidou" will also be formed. "The new business form of application has become the core foundation and power source of the new layout for the construction and development of the national comprehensive space-time system. Therefore, the future development trend of Beidou chips is functional integration and performance optimization. It needs to integrate communications, Internet of Things and various sensors to become a booster to promote the development of the intelligent industry. Therefore, the smaller the chip process, the easier it is to integrate with various industries, and it can also make it more widely used and better promote the development of various industries.
The "2021 White Paper on the Development of China's Satellite Navigation and Location Services Industry" released by the China Satellite Navigation and Positioning Association shows that the overall output value of my country's satellite navigation and location services industry in 2020 will reach 403.3 billion yuan, an increase of about 16.9% over 2019. Among them, the core output value of the industry, including chips, devices, algorithms, software, navigation data, terminal equipment, infrastructure, etc. directly related to the research and development and application of satellite navigation technology, increased by about 11% year-on-year, reaching 129.5 billion yuan. The proportion is 32.11%, the growth rate is higher than last year. It can be seen that Beidou has been fully integrated into production and life and is flourishing.
In addition, China's domestic Beidou navigation chips have also begun to be widely used in all walks of life. The "2021 White Paper on the Development of China's Satellite Navigation and Location Services Industry" shows that by the end of 2020, the sales of domestic Beidou-compatible chips and modules have exceeded 150 million, and the quarterly shipment has exceeded 10 million; the terminal product society with Beidou positioning function The total number of possessions exceeds 1 billion units/set (including smartphones); in 2020, the total shipments of high-precision chips, modules and boards for centimeter-level applications in China will grow rapidly, exceeding 1 million pieces, and the main application scenarios include intelligent connected vehicles , UAVs, agricultural machinery, construction machinery, surveying and mapping instruments, robots and IoT terminals, etc., high-level high-precision applications are obviously ubiquitous and large-scale.
