On April 24, 2026, China marked another key milestone in its space-based internet infrastructure development with the successful launch of a batch of experimental satellites from the Xichang Satellite Launch Center located in the southwestern province of Sichuan. According to the China Aerospace Science and Technology Corporation, the country’s top state-owned space contractor, the mission lifted off at 2:35 p.m. Beijing Time, with a veteran Long March 2D liquid-fuel carrier rocket delivering the Space-based Internet Technology Demonstrator series satellites into their pre-planned orbits without incident.
This launch marks the ninth orbital deployment of satellites for the Space-based Internet Technology Demonstrator program, which kicked off with its inaugural mission back in July 2023. Among the new satellites placed into orbit is a platform developed by GalaxySpace, a leading private aerospace firm headquartered in Beijing. This particular spacecraft is designed to carry out cutting-edge technical trials for several critical next-generation satellite technologies, including broadband direct-to-device cellular communication, integrated space-ground network architecture, and other core enabling technologies for global satellite internet.
The launch is part of China’s broader, ambitious plan to build a large-scale low-Earth orbit satellite mega-constellation, which will consist of approximately 13,000 individual satellites working together to deliver comprehensive global internet coverage to users across the planet. This infrastructure will help bridge the digital divide for remote and underserved regions that lack access to traditional terrestrial broadband networks.
Produced by the Shanghai Academy of Spaceflight Technology, the Long March 2D rocket that carried out this mission is a proven workhorse of China’s launch fleet. Powered by liquid propellants, the rocket generates 300 metric tons of liftoff thrust, and is certified to deliver payloads of up to 1.2 tons into a 700-kilometer sun-synchronous orbit, making it well-suited for the deployment of this class of experimental communications satellites.
