Operations
The satellite was developed by the Chinese Academy of Space Technology (CAST) and is based on the DFH-4 platform. Its communications payload is composed of 33 operational transponders (19 in Ku band, 12 in Ka band and 2 in L band). The satellite will operate for 15 years on the geosynchronous orbit. Launch mass was around .
The DFH-4 (DongFangHong-4) platform is a large telecommunications satellite platform of the next generation. It provides high capability in output power and communication capacity ranking with international advanced satellite platforms.
The applications for the DFH-4 platform are not limited to high capacity broadcast communication satellites and it can be used as a tracking and data relay satellite, regional mobile communication satellite, etc.
The platform comprises propulsion module, service module and a solar array system. It has a payload capacity of 588 kg and an output power of 10.5 kW by the end of its lifetime. Its reliability by the end of its lifetime is more than a 0.78 industry ratio.
The platform is equipped with 22 Ku-band transponders (four 54 MHz and eighteen 36 MHz), three receiver antennas, and two transmission antennas.
The DFH-4 can support the transmission of 150~200 TV programs simultaneously to ground users using a 0.45 meter antenna device. The DFH-4 satellite also features strong capabilities against hostile disturbance and jamming. The satellite's power supply includes two 6 meter solar panels.
