• Asiasat 3 - . Payload: HGS-1 / HS 601HP. Mass: 3,400 kg (7,400 lb). Nation: China. Agency: Asiasat. Manufacturer: El Segundo. Program: Asiasat. Class: Communications. Type: Civilian communications satellite. Spacecraft: HS 601. USAF Sat Cat: 25126 . COSPAR: 1997-086A. Apogee: 35,964 km (22,346 mi). Perigee: 35,612 km (22,128 mi). Inclination: 5.50 deg. Period: 1,436.20 min.

  The spacecraft was left in a high inclination useless orbit by a failure of the DM-3 stage and became an insurance writeoff. Two trips around the Moon to remove the inclination under its new owner (Hughes) saw it back into very limited service (as HGS-1) by August 1998 over the Indian Ocean and available for sale at bargain rates. Operated in geosynchronous orbit at 150-154 deg W in 1998; 60 deg W in 1999. As of 5 September 2001 located at 59.68 deg W drifting at 0.024 deg W per day. As of 2007 Mar 8 located at 169.58W drifting at 0.011W degrees per day.

• Asiasat 3S - . Payload: HS 601HP. Mass: 3,463 kg (7,634 lb). Nation: China. Agency: Asiasat. Manufacturer: El Segundo. Program: Asiasat. Class: Communications. Type: Civilian communications satellite. Spacecraft: HS 601. USAF Sat Cat: 25657 . COSPAR: 1999-013A. Apogee: 35,795 km (22,241 mi). Perigee: 35,778 km (22,231 mi). Inclination: 0.00 deg. Period: 1,436.10 min.

  A replacement for Asiasat 3, placed in the wrong orbit by a Proton launch in 1997, Asiasat 3S carried C and Ku band transponders. The Blok DM3 upper stage placed it a 9,677 km x 35,967 km x 13.1 deg geosynchronous transfer orbit. Asiasat's on-board R4D apogee engine was to be used to raise perigee to geostationary altitude. Mass in transfer orbit was 3,463 kg, down to 2,500 kg after insertion in geostationary orbit. Operated in geosynchronous orbit at 105 deg E from 1999. As of 4 September 2001 located at 105.52 deg E drifting at 0.008 deg E per day. As of 2007 Mar 11 located at 105.46E drifting at 0.017W degrees per day.

• AsiaSat 4 - . Payload: HS 601HP / AsiaSat 1R. Mass: 4,042 kg (8,911 lb). Nation: China. Agency: AsiaSat. Manufacturer: El Segundo. Program: Asiasat. Class: Communications. Type: Civilian communications satellite. Spacecraft: HS 601. USAF Sat Cat: 27718 . COSPAR: 2003-014A. Apogee: 35,805 km (22,248 mi). Perigee: 35,772 km (22,227 mi). Inclination: 0.00 deg. Period: 1,436.20 min.

  Delayed from May 28, 2002, and January 13, February 5, and April 11, 2003. AsiaSat 4 was designed to provide broadcast, telecommunications and broadband multimedia services to the Asia Pacific region, and direct-to-home broadcast servic-es to Hong Kong, from its orbital position of 122 deg É East longitude.The satellite generated up to 9,600 watts using two sun-tracking four-panel solar wings covered with triple-junction gallium arsenide solar cells. AsiaSat 4 was to operate in C-band and Ku-band. The satellite carried 28 active transponders with six spares in C-band, powered by 55-watt traveling-wave tube amplifiers (TWTAs), and 20 active transponders with four spares in Ku-band, powered by 140-watt TWTAs. The C-band payload was designed to offer pan-Asian coverage, similar to AsiaSat 3S, also a 601HP model. The Ku-band payload provided high power, and spot beams for selected areas in either the Fixed Satellite Service frequency band or in the Broadcast Satellite Service frequency band. As of 2007 Mar 10 located at 122.23E drifting at 0.011W degrees per day.

• Asiasat 5 - . Mass: 3,760 kg (8,280 lb). Nation: China. Agency: ILS. Program: Asiasat. Class: Communications. Type: Civilian communications satellite. Spacecraft: FS-1300. USAF Sat Cat: 35696 . COSPAR: 2009-042A. Apogee: 35,791 km (22,239 mi). Perigee: 35,781 km (22,233 mi). Inclination: 0.00 deg. Period: 1,436.10 min. Provided C-band and Ku-band communications services..
