China’s Asia-Pacific-6E (APStar-6E) communication satellite, featuring all-electric propulsion, has successfully completed its in-orbit testing and commenced operational services, according to the China Aerospace Science and Technology Corporation (CASC). The satellite, which began its operational phase on Monday, represents a significant technological milestone for China’s space program.
APStar-6E is built on the innovative DFH-3E satellite platform, a smaller and more efficient framework designed to enhance the regional information industry by providing cost-effective, high-throughput broadband satellite resources. The satellite’s manufacturers highlight its potential to establish robust communication systems in geographically challenging areas, thus facilitating better connectivity in remote regions.

Launched in January from the Xichang Satellite Launch Center aboard a Long March-2C carrier rocket, APStar-6E is distinguished as the world’s first telecommunications satellite to achieve fully autonomous orbit transfer. This groundbreaking process involved the satellite independently moving from low Earth orbit to geostationary orbit using its electric propulsion systems. After detaching from its independent propulsion module, the satellite utilized these systems to position itself accurately in synchronous orbit.
Weighing 4,607 pounds (2,090 kilograms), APStar-6E was ordered by APT Satellite, a Hong Kong-based company, and is set to join their existing fleet of telecommunications satellites serving the Asia-Pacific region.
The satellite’s all-electric propulsion system and modular DFH-3E platform allow for efficient configuration and operation, catering to specific communication needs while maintaining a versatile framework that includes essential components like power sources, propulsion, and orbital control devices.

The satellite carries 25 Ku-band transponders and three Ka-band gateway transponders, collectively providing a communication throughput of 30 gigabytes per second. This high capacity is expected to significantly boost the regional information infrastructure, offering enhanced broadband services and supporting various communication applications across the Asia-Pacific.
Wang Min, the satellite’s chief designer, emphasized that APStar-6E’s successful deployment underscores the advanced capabilities of China’s satellite technology. The satellite’s ability to autonomously raise its orbit and maintain long-term autonomous operations marks a leap forward in intelligent satellite autonomy, enhancing the global competitiveness of China’s communication satellite platforms.
The development and successful launch of APStar-6E were orchestrated by China Great Wall Industry Corporation (CGWIC), a subsidiary of the state-owned CASC. This achievement not only demonstrates China’s growing expertise in satellite technology but also solidifies its presence in the international space industry. As the APStar-6E begins its operational life, it is poised to contribute significantly to regional connectivity and the broader development of global satellite communications.
