[edit] Paksat Project

Pakistan's Paksat-1 was originally known as Palapa-C1. It was launched by Hughes Space and Communications Company for Indonesia. Later Indonesia declared the satellite unusable after an electric power anomaly. The insurance claims were paid and the title was transferred to Hughes Space and Communications Company. ^[1]. HGS-3 was then acquired by Pakistan from M/s Hughes Global Services on "Full Time Leasing " and relocated to Pakistan's reserved slot at 38 Degree. After a series of orbital maneuvers, the Satellite was stabilized at the final location on December 20, 2002 with 0-degree inclination. The satellite is in position at the Pakistani-licensed orbital location, 38° east longitude. Paksat 1 is operational and is ready to offer services.

[edit] Services

The services include low cost, high quality satellite communications in both C- and Ku-bands to customers in Pakistan, Africa, and the Middle East. Paksat-1’s 30 C-band transponders and 4 Ku-band transponders provide total range of satellite communication capabilities. Services are priced well below market rates. The satellite is ideal for businesses looking for low cost-of-entry to the satellite service market or to leverage the advantages of satellite communications. ISPs can use the satellite as a highly cost effective means to access the European or American Internet and to extend their reach into remote areas where broadband terrestrial capacity is not available.

[edit] Paksat Future Projects

Telesat, one of the world’s leading satellite operators, announced on March 13, 2007 that it has signed a consulting contract with the Pakistan Space and Upper Atmosphere Research Commission (SUPARCO), Pakistan’s national space agency. Under the agreement, Telesat will assist SUPARCO in the procurement and launch of the Paksat-1R satellite, which will replace the existing Paksat-1 in 2010.

“Telesat’s new relationship with Pakistan’s national space agency is testimony to Telesat's longstanding reputation for integrity, reliability and deep expertise in the field of satellite communications services,” said Dan Goldberg, Telesat’s president and CEO. “For more than 35 years, Telesat has been a pioneer in leading-edge satellite communications and it’s a privilege to put that experience to work to benefit the people of Pakistan.”

Telesat’s services will include initiating, evaluating and recommending manufacturer proposals for Paksat-1R, and providing technical and commercial advisors during the negotiation process. Telesat will also help oversee the construction of the new satellite, and will monitor the launch and in-orbit testing services.

“SUPARCO is committed to explore and expand our country’s satellite technology, and Telesat can certainly help in reaching this goal,” said a SUPARCO spokesperson. “Telesat shares SUPARCO’s vision and passion for developing advanced satellite services for the benefit of millions of people, everyday.”
