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,[6] and renamed HGS-3, and was then acquired by Pakistan from Hughes Global Services on "Full Time Leasing" and relocated to Pakistan's reserved orbital position at 38° East.
HGS-3
Hughes Global Services purchased the satellite and renamed HGS-3.[5]
Pakistan's government approved the acquisition on 3 July 2002[7] and the leasing with Hughes Global Services was agreed on 6 August 2002.[8] The satellite started moving to its new orbital position on 5 December 2002 [9] and it went through a name change from Anatolia-1 to Paksat-1 on 18 December 2002.[10] After a series of orbital maneuvers, the satellite was stabilized at its final location on 20 December 2002 with 0° inclination. The satellite is in position at the Pakistani-licensed orbital location, 38° East longitude. The satellite was acquired for a cost of around five million dollars.[11]
Mission
The services include satellite communications in both C-band and Ku-band 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.
Payload characteristics
30 C-band transponders and 4 Ku-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
Number of transponders
24 in standard C-band 6 in extended C-band
Redundancy
All redundancy available
Channel bandwidth
36 MHz
Uplink frequency band
5925 MHz – 6665 MHz
Downlink frequency
band 3400 MHz – 4200 MHz
Beams
Southern regions Northern regions
Beam connectivity
All transponders can be switched independently to downlink in the southern beam. Many transponders can downlink in the northern beam. All transponders can be switched independently to uplink from either beam
Paksat-1 has two beams each in both C-band and Ku-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 Ku-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 13 March 2007, that it had 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.[12]
