Paksat-1R
PakSat-1R (or PakSat-1 Replacement) is an advanced geosynchronous and communications satellite that is manufactured 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 ageostationary 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.〔http://italk.pk/post/2011/08/12/Pakistan’s-first-Communications-Satellite-PAKSAT-1R-launched.aspx〕〔http://www.dawn.com/2011/08/11/pakistans-first-communications-satellite-paksat-1r-launched.html〕 ==History==
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.
