China's First All-Electric Communication Satellite Successfully Enters Operational Phase

The APStar-6E, also known as Asia-Pacifc-6E, has reached a critical milestone by successfully completing its in-orbit technology verification and ground station reviews in Hong Kong. According to the China Great Wall Industry Corporation (CGWIC), all tests detailed in its in-orbit protocol have been fulfilled, with the satellite’s payload performing exactly as expected based on previous ground tests and contractual requirements.

Developed by the China Academy of Spacecraft Technology on the DFH-3E satellite platform, the APStar-6E is the first satellite of its type featuring dual Hall/Ion electric propulsion systems. These advanced systems have met the necessary station-keeping criteria, allowing the satellite to autonomously maneuver into its designated geosynchronous orbit following its launch. Initially launched alongside its independent propulsion module on January 13, 2023, via a Long March-2C rocket from the Xichang Satellite Launch Center, it separated from the module on January 23 and successfully transitioned to geosynchronous orbit by June 10, 2024.

Now positioned at 134°E alongside its counterparts APStar-6C and APStar-6D, the APStar-6E is designed to offer highly cost-effective, high-throughput broadband communication services, especially across the Southeast Asian region. Equipped with 25 Ku-band user beams and 3 Ka-band gateway beams, it provides a communication capacity of roughly 30 Gbps and is expected to operate for 15 years. The satellite’s successful operation marks a significant advancement in delivering autonomous orbit transfer capabilities and long-term operational autonomy, enhancing the overall competitiveness and intelligence of China’s satellite platforms. CGWIC, a subsidiary of the state-owned China Aerospace Science and Technology Corporation, has a proven track record in delivering international communications satellite programs to various countries and regions around the world.
