Paksat-1E^[1] , formerly Palapa C1, HGS-3 and Anatolia 1 is a geosynchronous communications satellite owned by Boeing and operated under lease by Paksat. It was launched on 31 January 1996 as Palapa C1 for Indonesia, and is expected to be replaced by PAKSAT-1R in 2011.^{[citation needed]} PAKSAT-1 operated at an orbital location of 38° East Longitude and offered C and K_u band coverage in over 75 countries across Europe, Africa, Middle East, South and Central Asia. Its customers included government organizations, TV broadcasters, telecom companies, data and broadband internet service providers.

History

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. ^[2] 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 its final location on December 20, 2002 with 0-degree inclination. The satellite is in position at the Pakistani-licensed orbital location, 38° east longitude.

Services

The services include satellite communications in both C band and K_u band to customers in Pakistan, Africa and the Middle East. Paksat-1’s 30 C-band transponders and 4 K_u band transponders provide total range of satellite communication capabilities. The services are reasonably priced and 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 means to access the European or American Internet and to extend their reach into remote areas where broadband terrestrial capacity is not available.

Paksat-1 Payload Characteristics

PAKSAT-1’s 30 C-band transponders and 4 K_u band transponders provide the total range of satellite communications capabilities. The satellite is in a geostationary orbit at 38° East Longitude, and carries high power payloads in both bands.

Payload characteristics of PAKSAT-1 are as below:

C-Band Payload Characteristics

Paksat footprints

Paksat-1 has two beams each in both C and K_u bands i.e., C1, C2 and K1, K2, respectively. In C-band, C1 (Southern Beam) covers mainly African Continent and Middle East. The C2 (Northern Beam) covers South Asia, Middle East, African Continent, Central Asian States and Southern Europe. In K_u band, K1 (Southern Beam) covers mainly Middle East and Eastern Africa. K2 {Northern Beam) covers South Asia, Middle East and Central Asian States.

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 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.^[3]

“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.”
