Launch
The PakSat-1R was launched on 11 August 2011 from the Xichang Satellite Launch Center in Sichuan province, China, by a Long March 3B/E (Chang Zheng-3B/E) launch vehicle. In 2010, China provided loans for setting up communication facilities at the SUPARCO Satellite Ground Station.[11]

The DFH-4 (DongFangHong-4) satellite bus is a large telecommunications satellite platform – a new generation of hardware based on high output power and communication capacity, ranking alongside international advanced satellite platforms. The applications for the DFH-4 platform aren't limited to high-capacity broadcast communication satellites and can be used to tracking and data relay satellites, regional mobile communication satellites, etc. The satellite bus comprises propulsion module, service module and solar array. It has a payload capacity of 588 kg and an output power of 10.5 kW by the end of its lifetime. Its design lifetime is 15 years and its reliability by the end of its lifetime is more than 0.78.
Based on versatility, inheritance, expandability and promptness principles and mature technology, the platform will meet the needs of international and domestic large communication satellite markets. The satellite is equipped with three receiver antennas and two transmission antennas. It can support the transmission of 150-200 television programs simultaneously to ground users using a 45 cm (18 in) antenna device.[13]
