China Advances Satellite Internet Technology with Long March 2D Launch
China successfully launched a Long March 2D rocket carrying satellite internet test satellites, focusing on direct-to-cell broadband and space-ground network integration. This marks the sixth launch in the satellite internet program as China pushes forward its capabilities in satellite communications. The mission is part of a broader strategy to enhance sovereign internet access and boost the nation’s overall space infrastructure in 2025.
On April 1, 2025, China successfully launched a Long March 2D rocket from the Jiuquan Satellite Launch Center, marking another step in its satellite internet technology tests. This launch, occurring at midnight local time, involved insulation tiles dropping from the payload fairing as the rocket ascended into the clear azure sky. The Shanghai Academy of Spaceflight Technology (SAST) confirmed the launch success and identified the payload as a satellite internet technology test satellite.
The primary purposes of the satellite include technical testing and verification for direct-to-cell satellite broadband and integration of space-ground networks, though SAST withheld specific details and images of the satellite. Notably, the Ministry of Industry and Information Technology (MIIT)’s Radio Management Bureau reported that this launch carried four test satellites, labeled 0001-0004, featuring Ka and other frequency payloads.
This mission represents China’s sixth launch of satellite internet technology test satellites, coming after various missions since July 2023 using different rockets. Authorities have provided minimal official information about these satellites, though development is credited to the China Academy of Space Technology (CAST).
China is concurrently advancing two low Earth orbit megaconstellation projects, Guowang and Qianfan/Thousand Sails, while continuing its satellite internet technology missions. Their objectives might include testing new satellite generations or system features such as propulsion and thermal control. Additionally, China has launched three high orbit internet satellites throughout 2024, operating from geostationary positions, with limited details disclosed about their purposes, leading to speculation about potential military applications.
This expansion contributes to China’s comprehensive communications infrastructure in space, focusing on self-sufficiency for internet services. The government prioritized satellite internet as part of its strategy in 2020, aligning with broader communications projects involving satellites in medium Earth and geostationary orbits.
The April 1 mission marks the 17th orbital launch for China in 2025, following the Long March 7A rocket’s deployment of the classified TJS-16 satellite. With an ambitious target of over 100 launches this year, fueled by increased commercial endeavors and innovations in launching capabilities, China plans notable missions, including the human spaceflight initiatives Shenzhou-20 and 21 and the Tianwen-2 asteroid sample return mission anticipated in May.
In summary, China’s recent Long March 2D launch illustrates its ongoing commitment to developing a robust satellite internet infrastructure and advancing its capabilities in space technologies. As the nation pursues multiple projects, including low Earth orbit megaconstellations and geostationary satellites, it aims to enhance its sovereign access to space-based internet services, minimizing reliance on foreign technologies. The country has set ambitious goals for future launches, indicating a significant expansion in its space exploration and usage strategies.
