China News Service, Beijing, September 16 (Reporter Sun Zifa) The reporter learned from the National Key Laboratory of Integrated Space-Time Network and Equipment Technology built and operated by China Electronics Network Communications Research Institute that at the 5th Beidou Scale Application International Summit held from September 15 to 16, cutting-edge technologies such as China's new generation of space-terrestrial collaborative PNT (positioning, navigation, timing) network were showcased, empowering new developments in Beidou scale applications with full-stack capabilities.
As a core enterprise in the Beidou industry, China Electronics Network Communications Research Institute continues to deepen the construction of a comprehensive PNT system and strives to build the "chip-terminal-system-application-testing and certification" full-chain capability. This time, it participated in the Beidou Scale Application International Summit and set up six major sections, including space-time innovation, space-time equipment, space-time security, space-time network, industry applications, and testing and certification, to fully present the innovation results of the entire chain of space-time information.
Among them, the space-time innovation section focuses on comprehensive PNT cutting-edge technology, displaying achievements such as a new generation of space-ground collaborative PNT network, a high-precision wide-area distributed time-frequency transmission system, and space-space-ground collaborative multi-source fusion positioning and mapping terminals.
The new generation of space-to-ground collaborative PNT network relies on the PNT cloud platform and integrates space-based, ground-based, and indoor subnet resources to create a comprehensive test network integrating scientific research, application, and technology research; the high-precision wide-area distributed time-frequency transmission system overcomes the "last mile" problem of time-frequency transmission.
In the space-time equipment section, a variety of independently developed Beidou and low-orbit fusion core equipment are on display, including Beidou railway station centralized control terminals, locomotive and on-board early warning communication terminals, locomotive and on-board integrated communication antennas, Beidou high-precision verification terminals, low-orbit navigation enhanced payloads, and low-orbit communication and guidance fusion information. A series of products such as the Beidou-3 regional short message, Tiantong-1 satellite Internet of Things, 5G, long-distance radio frequency communication and other technologies can realize global blind zone communication and have functions such as high-precision solution and limit intrusion alarm to ensure the safety of railway stations and locomotive operations.
The space-time security section displays safety protection products for civil aviation Beidou applications such as GNSS (Global Navigation Satellite System) performance monitoring and evaluation systems.
In the space-time network section, the short message testing equipment for mass consumer terminals is displayed, which can solve the Beidou short message testing needs of mass consumer terminals such as mobile phone terminals, smart watches, and vehicle-mounted modules.
The industry application section shows the effectiveness of Beidou technology in multiple fields, covering emergency rescue, mining industry, smart parking, modern agriculture and other scenarios.
The testing and certification section demonstrates the complete inspection, testing and quality assessment service capabilities of Beidou and satellite Internet terminal products.
CETC stated that in the future, it will continue to promote the integrated development of Beidou technology with emerging technologies such as satellite Internet, mobile Internet, big data, and the Internet of Things, empower the development of emergency, transportation, mining and other industries, and help China's Beidou industry achieve a higher level of scale and industrial development.
It is understood that as the only national key laboratory in the field of satellite navigation, the National Key Laboratory of Integrated Space-Time Network and Equipment Technology is also known as "Chinese Space-Time". Its overall goal is to support the integration of space-time reference transmission and maintenance services for land, sea, air and space, and determine four major research directions: space-time unification and transmission network, multi-dimensional signal and monitoring and evaluation, space and ground enhancement and combined positioning, intelligent navigation and space-time services.
