  • Telstar 6 - . Mass: 3,700 kg (8,100 lb). Nation: USA. Agency: Skynet. Manufacturer: Palo Alto. Program: Telstar. Class: Communications. Type: Civilian communications satellite. Spacecraft: FS-1300. USAF Sat Cat: 25626 . COSPAR: 1999-005A. Apogee: 35,796 km (22,242 mi). Perigee: 35,777 km (22,230 mi). Inclination: 0.0000 deg. Period: 1,436.10 min. Loral Skynet's Telstar 6 had a mixed C and Ku band communications payload. The Block DM3 upper stage released Telstar 6 in a 6638 km x 35,756 km x 17.4 degree geosynchronous transfer orbit. After the first burn of its on-board R-4D engine on February 18, Telstar 6 was in a 15,037 km x 35,800 km x 7.9 deg transfer orbit heading for its final geosynchronous slot at 93 deg W Positioned in geosynchronous orbit at 93 deg W in 1999. As of 2 September 2001 located at 93.01 deg W drifting at 0.004 deg W per day. As of 2007 Mar 11 located at 93.03W drifting at 0.007W degrees per day.

1999 September 25 - . 06:29 GMT - . Launch Site: Kourou. Launch Complex: Kourou ELA2. LV Family: Ariane. Launch Vehicle: Ariane 44LP. LV Configuration: Ariane 44LP-3 V121.
  • Telstar 7 - . Mass: 3,790 kg (8,350 lb). Nation: USA. Agency: Skynet. Manufacturer: Palo Alto. Program: Telstar. Class: Communications. Type: Civilian communications satellite. Spacecraft: FS-1300. USAF Sat Cat: 25922 . COSPAR: 1999-052A. Apogee: 35,794 km (22,241 mi). Perigee: 35,778 km (22,231 mi). Inclination: 0.0000 deg. Period: 1,436.10 min. Telstar 7, owned by Loral Skynet, had 24 C-band and 24 Ku-band transponders. Dry mass was 1537 kg. After placement in final geosynchronous orbit it provided communications for North America from a position at 129 degrees East longitude. Sold to Intelsat in March 2004 and renamed IA-7. The satellite had a power failure on November 28, 2004 and was briefly declared lost. Intelsat recovered control of the satellite by December 4. As of 2007 Mar 9 located at 129.01W drifting at 0.007W degrees per day.

2004 January 11 - . 04:13 GMT - . Launch Site: Kiritimati. Launch Pad: 0.0 N x 154.0 W. Launch Platform: ODYSSEY. LV Family: Zenit. Launch Vehicle: Zenit-3SL. LV Configuration: Zenit-3SL 12.
