PakSat-1R (or PakSat-1 Replacement) is an advanced geosynchronous and communications satellite that was manufactured by China Great Wall Industry Corporation (CGWIC) and operated by the Space and Upper Atmosphere Research Commission (Suparco), an executive space authority of the government of Pakistan.
The PakSat-1R was developed and built as a geostationary telecommunications satellite and was launched from Xichang, China, at 16:15 UTC on 11 August 2011. Launched on the Long March 3B rocket, the satellite has a design life of 15 years with initial goals to provide broadband internet access, digital television broadcasting, remote and rural telephony, emergency communications, tele-education and tele-medicine services across South and Central Asia, Eastern Europe, East Africa and the Far East. The satellite successfully took over the operations of its predecessor, the PakSat-1E satellite leased by Pakistan, in geostationary orbit at 38° East.
In December 2001, the Suparco negotiated to lease the Palapa-C1 satellite and designated it as PakSat-1E in an attempt to avert the orbital slot crises. It was acquired after an anomaly in the electrical system of the satellite on 24 November 1998. A module for controlling the hydro accumulators had failed and an American contractor, Hughes Global Services (HGS), managed to develop a strategy that allowed the continued use of the satellite in geostationary orbit. The satellite was eventually leased by Pakistan as PakSat-1E at 38°East in geostationary orbit and had been active since April 2004. During this time, the Suparco began developing the geosynchronous satellite to replacing the aging PakSat-1E as part of the new space policy announced by the Government of Pakistan in 2008.
