en.Wedoany.com Reported - On June 29, at the Space Computing Forum of the 2026 Global Digital Economy Conference held in Zhongguancun, Haidian District, Beijing, the TianSuan Constellation completed the launch of new ground stations and their integration into the national network, with two new ground stations in Beijing and Hefei officially becoming operational. Previously, the TianSuan Constellation had established the East China Ground Station and the South China Ground Station, forming a preliminary multi-regional collaborative satellite-ground communication and computing service support system. With the integration of the Beijing and Hefei ground stations, the constellation's capabilities in satellite tracking, telemetry and command (TT&C), data reception, task scheduling, and satellite-ground collaborative computing will be further enhanced, providing new ground infrastructure support for China's space computing network construction, integrated space-air-ground services, and the expansion of commercial aerospace applications.
Ground stations are crucial gateways to the space computing network. Satellites in orbit require TT&C commands, task scheduling, data return, and computational collaboration. A single ground station struggles to meet the demands of multi-regional, multi-mission, and high-frequency communication.
With the Beijing and Hefei ground stations operational, the TianSuan Constellation's ground-side service nodes have been further expanded. The Beijing node facilitates connections with universities, research institutions, industry alliances, and space computing application scenarios. The Hefei node can leverage Anhui's foundation in aerospace information, low-altitude economy, intelligent computing, and data applications to undertake satellite data reception, processing, and industry validation tasks. Working in conjunction with the established East China and South China ground stations, the TianSuan Constellation can conduct satellite TT&C, data reception, link scheduling, and satellite-ground collaborative experiments across more regions, reducing the pressure on single access points and improving mission response efficiency.
The focus of the TianSuan Constellation's construction is not merely "launching satellites," but rather enabling satellites, ground stations, network protocols, space servers, and application systems to collectively form an open, testable, and reusable space-air computing platform. Traditional satellites typically undertake observation, communication, or navigation tasks, with data processing relying heavily on ground centers. The space computing network aims to place a portion of computing capability into orbit, equipping satellites with on-orbit processing, on-orbit collaboration, and inter-satellite communication capabilities. With the national ground station network integration, the ground segment can dispatch tasks to satellites more quickly and receive processed data results from orbit more stably, supporting experiments in remote sensing, the Internet of Things (IoT), low-altitude economy, emergency communications, and future 6G space-air networks.
To date, the TianSuan Constellation has launched a total of eight satellites, including BUPT-1, BUPT-2, and BUPT-3, and has achieved multiple on-orbit technological results. These achievements include the world's first spaceborne 5G core network system, the world's first cloud-native satellite platform, the dual-kernel high-reliability satellite native operating system RROS, and space servers. As the first satellites of the TianSuan Constellation Phase II, BUPT-2 and BUPT-3 integrate payloads and application systems such as inter-satellite high-capacity laser communication, snapshot hyperspectral remote sensing cameras, space servers, IoT experimental platforms, and satellite-ground IP-based networks, conducting on-orbit experiments for space-air computing, 6G networks, and intelligent remote sensing.
Space servers are key equipment within this system. They enable satellites to function not just as data collection terminals, but also to undertake some data processing, task management, and application execution functions.
In remote sensing scenarios, satellites generate vast amounts of raw data daily. However, due to limitations in link bandwidth, transit time, and ground reception windows, not all data can be transmitted back to the ground in a timely manner. With on-orbit computing capabilities, satellites can first perform preliminary screening, compression, identification, and processing of images, spectra, IoT data, or mission information, before transmitting the more valuable data back to Earth. This not only alleviates the reception pressure on ground stations but also improves data timeliness for applications such as disaster monitoring, ocean observation, traffic inspection, agricultural remote sensing, and urban management.
The addition of the Beijing and Hefei ground stations will also enhance the TianSuan Constellation's ability to support multi-mission concurrency and satellite-ground collaborative computing. As the satellite constellation enters the networking phase, the capability of a single satellite is merely foundational. What truly impacts service quality is the ability of satellites within the constellation to collaborate, the rapid scheduling of ground nodes, and the rational allocation of data between space and ground. More ground stations provide greater flexibility in mission access paths, higher utilization rates of satellite transit windows, and better support for future large-scale open experiments and industry application integration.
From the perspective of commercial aerospace applications, the national network integration of the TianSuan Constellation will provide more enterprises and research teams with an experimental environment for space-air computing. Stable satellite-ground links and schedulable computing platforms are essential for the low-altitude economy, satellite IoT, integrated space-air-ground communication, intelligent remote sensing, emergency management, and edge AI applications. With the Beijing and Hefei ground stations operational, the TianSuan Constellation's ground service capabilities have shifted from single-point construction to multi-regional collaboration. Future efforts can focus on conducting more engineering experiments around industry data processing, on-orbit software validation, spaceborne AI applications, and space-terrestrial integrated networks.
The addition of new ground stations and the completion of national network integration by the TianSuan Constellation mark a new phase for China's space computing infrastructure, moving beyond satellite launches and individual technology validation towards the collaborative advancement of constellations, ground stations, computing platforms, and application services. As more satellites, ground stations, and industry scenarios are integrated, the space computing network will evolve from a mere aerospace research concept into a new type of infrastructure supporting satellite data processing, 6G space-air networks, the low-altitude economy, and commercial aerospace services.
