APT Satellite successfully launched the Apstar-6C into orbit with the Long March-3B (LM-3B) launch vehicle from Xichang Satellite Launch Center in Sichuan province of China. Both the satellite and the rocket were developed by the China Aerospace Science and Technology Corporation (CALT). Apstar-6C is the 12th satellite placed in-orbit under a contract between China Great Wall Industry Corporation (CGWIC), a subsidiary of China Aerospace Science and Technology Corporation (CASC), and APT Satellite signed in Oct. 2015.
Apstar-6C, a replacement satellite of Apstar-6, is the second DFH-4 platform satellite that APT Satellite has procured from CGWIC. Positioned at 134 degree east, the geostationary satellite is equipped with 45 transponders in C, Ku, and Ka bands, with a designed service life of 15 years, providing high power transponder services to customers across the Asia-Pacific region for In-Flight Connectivity (IFC), video contribution/distribution, Direct-to-Home (DTH) service and cellular backhaul.
The LM-3B is capable of launching a payload of up to 5,500kg into standard Geostationary Transfer Orbit (GTO). The launch marks the 46th mission of the of LM-3B launch vehicle and the 273rd flight of Long March launch vehicle family. Meanwhile, APT Mobile SatCom, a corporation established by APT Satellite in Mainland China has been investing and developing Apstar-6D, the third Chinese-made satellite in the Apstar satellite fleet, which will provide high-throughput broadband satellite communication services in the Asia-Pacific region. The Apstar-6D is also designed and manufactured by CGWIC as the prime contractor.
