Developed using China's homegrown DFH-4 platform for the Hong Kong-based APT Satellite Company Limited, 'APSTAR-9' is designed to stay in service for at least 15 years.
It will replace its predecessor 'APSTAR-9A', which was launched in 1998 with a designed mission life of 15 years also.
Monitoring data collected 26 minutes after the satellite's launch at 0:16 am Beijing time indicated that it had separated from the rocket and reached its designated orbit, state-run Xinhua news agency reported.
Today's launch is the 214th mission of the Long March carrier rocket series developed by China Aerospace Science and Technology Corporation (CASTC).
