Qianfan Constellation Completes Fourth Batch: Global Seamless Internet Coverage Nearing Reality
China's Qianfan constellation completed its fourth batch of 108 satellite launches, reaching 576 total satellites in orbit, with global seamless coverage expected by Q2 2028.
China's Qianfan (Thousand Sails) constellation completed the launch of its fourth batch of 108 low-Earth orbit communication satellites on December 15, bringing the total number of satellites in orbit to 576. Led by the Shanghai Engineering Center for Microsatellites, each satellite weighs approximately 300kg at an orbital altitude of about 1,100km. Unlike SpaceX's Starlink, Qianfan uses a Ka+V dual-band design with a theoretical single-satellite bandwidth of 20Gbps. The project expects to complete all 1,296 satellites by Q2 2028, providing global seamless internet coverage with a focus on serving Belt and Road Initiative countries.
