Spatio-temporal information is the key element for human beings to use information resources to serve production and life, and BEIDOU chip is the application cornerstone of building China's spatio-temporal information security. In the era of Internet of Everything, the position information and time data provided by BEIDOU navigation, positioning and timing technology are the core keys to connect the "virtual" and "real" world, and the innovative application of spatio-temporal information and other data integration is the core resource and innovation main line to realize intelligent information service. Since the development of BEIDOU system in China, it has been proposed that the construction of BEIDOU system is to master the national independent and controllable time and space benchmarks and provide ubiquitous services.
BEIDOU navigation and positioning information is the key information in spatio-temporal data, and its authenticity and confidentiality are the prerequisites for the safety and reliability of various applications. Once the accurate navigation and positioning data is tampered with and stolen, it will cause serious economic losses, and even endanger people and even important equipment, infrastructure and national defense security. How to avoid that information being stolen and tampered with in the transmission link has become the urgent need of BEIDOU industry application. Designing a hardware encryption unit in BEIDOU chip to realize "source-level" location information encryption output is the key to solve this hidden danger, and will also provide the underlying security support for industrial applications based on location information.
BEIDOU GNSS satellite navigation and positioning chip developed by ALLYSTAR supports "source-level" location information security encryption technology, encrypts the transmitted data, ensures the confidentiality of the transmitted data, meets the requirements of BEIDOU location information security and trusted location service in key important industries, ensures the intrinsic security of China's spatio-temporal information from the technical level, and builds a secure base for China's digital construction.
BEIDOU chip is the key guarantee for BEIDOU application to be autonomous and controllable. BEIDOU chip industry, as the upstream of BEIDOU industrial chain, is the foundation and support of industrial development. Improving the technical level of BEIDOU satellite navigation and positioning chips, launching products with higher performance and better cost performance, getting rid of the dependence on high-end chip products of foreign manufacturers, and realizing effective localization substitution are the key steps to ensure the independent and controllable application of BEIDOU. Only by relying on independent, controllable and advanced BEIDOU chips can we completely solve the potential threats to BEIDOU application and space-time information security in China.
BEIDOU chip builds a solid foundation for the construction of national integrated PNT (Positioning, Navigation and Timing) system. At present, China is accelerating the construction of national comprehensive PNT system with BEIDOU system as the core, with the goal of providing a safe, reliable, better performance, ubiquitous and ever-present time and space infrastructure. By 2035, China will build a more ubiquitous, integrated and intelligent national integrated positioning and navigation time service system. After the signal of satellite navigation and positioning system is transmitted to the ground through satellite, the core technology is that the chip receives the signal and solves it, so as to obtain accurate position and time information. Therefore, the basic capability of the whole BEIDOU The chip developed by ALLYSTAR is located in the key link of BEIDOU industrial chain and the core part of the ground receiving section, which has built a solid foundation for the completely independent and controllable application of national integrated PNT system.
BEIDOU chip will promote industrial integration, innovation and development. With the increasing demand for spatio-temporal information in various industrial application fields, the development of BEIDOU industry must integrate innovative applications in order to realize the application development of BEIDOU industry and promote the innovation of industrial application technology and application mode. Satellite navigation and positioning chip, as the core position information, is the key factor of information fusion. Improving the technical level of BEIDOU satellite navigation and positioning chip can not only promote the integration of industrial data and information, but also promote the technological development of all walks of life and upgrade the industrial structure.
Chip-level BEIDOU high-precision positioning solution empowers the industry to develop with high quality and safety
BEIDOU global system construction has been opened and operated stably for more than two years. In key industries, domestic BEIDOU chip enterprises represented by ALLYSTAR are accelerating core technology research and constantly breaking through technical difficulties. Through independent research and development, chips such as frequency emission and baseband are highly integrated to realize high-precision board "chipping", reduce the cost and threshold of high-precision positioning application, provide high-performance, low-cost and cost-effective chip-level BEIDOU high-precision positioning solutions for industrial applications, promote the large-scale application of domestic BEIDOU chips, and support the high-quality development of BEIDOU industry.
In order to fill the gap in the field of meteorological sounding satellite navigation chips in China, the Meteorological Exploration Center of China Meteorological Administration and domestic BEIDOU chip manufacturers successfully developed the "Spring Equinox I" meteorological sounding chip module. After repeated experiments, the chip module has obvious advantages such as high precision positioning, high integration, high reliability, low power consumption, low cost, hardware standardization and data processing standardization. Once the meteorological special module is launched, it will break the monopoly of satellite navigation chip technology in the international sounding market. In July 2019, the first batch of "Spring Equinox I" went offline. On May 1, 2021, a new radiosonde equipped with this chip module was successfully launched at Anqing Radiosonde Station in Anhui Province. The chip module can support BEIDOU satellite navigation system, Global Positioning System (GPS) and other navigation systems.
