Sirius Chronology


2000 June 30 - . 22:08 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/24. LV Family: Proton. Launch Vehicle: Proton-K/DM-2M. LV Configuration: Proton-K/DM-2M (DM3) 400-01.
  • Sirius 1 - . Payload: CD Radio 1. Mass: 3,800 kg (8,300 lb). Nation: USA. Agency: Sirius. Manufacturer: Palo Alto. Program: Sirius. Class: Communications. Type: Civilian communications satellite. Spacecraft: FS-1300. USAF Sat Cat: 26390 . COSPAR: 2000-035A. Apogee: 47,107 km (29,270 mi). Perigee: 24,465 km (15,201 mi). Inclination: 63.4000 deg. Period: 1,436.10 min. Digital Audio Radio Satellite, used for transmission of S-band radio broadcasts direct to receivers in cars in the United States. Sirius 1 was inserted into an initial 6,166 x 47110 km x 63.4 deg transfer orbit by the Proton-K's Blok DM3 upper stage. The satellite's R4D liquid apogee engine made several burns to raise the orbit to 24,388 x 47,097 km x 63.3 deg by July 8. This elliptical, inclined 24 hour orbit had a 24 hour period, designed to keep the satellite between longitude 60W and 140W, with apogee over the northern hemisphere. Stationed at 66 deg W. Positioned in geosynchronous orbit at 66 deg W in 2000. As of 6 September 2001 located at 65.59 deg W drifting at 0.015 deg E per day. As of 2007 Mar 9 located at 65.37W drifting at 0.004E degrees per day.

2000 September 5 - . 09:43 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/23. LV Family: Proton. Launch Vehicle: Proton-K/DM-2M. LV Configuration: Proton-K/DM-2M (DM3) 400-02.
  • Sirius 2 - . Mass: 3,800 kg (8,300 lb). Nation: USA. Agency: Sirius. Manufacturer: Palo Alto. Program: Sirius. Class: Communications. Type: Civilian communications satellite. Spacecraft: FS-1300. USAF Sat Cat: 26483 . COSPAR: 2000-051A. Apogee: 47,090 km (29,260 mi). Perigee: 24,480 km (15,210 mi). Inclination: 63.9000 deg. Period: 1,436.00 min. Sirius Radio's Sirius 2 was launched into a 144 x 168 km x 64.8 deg parking orbit. The Blok DM3 stage then made two burns to deliver Sirius 2 to an elliptical 6192 x 47057 km x 63.4 deg orbit. The was to provide digital radio broadcasts to mobile users in North America. Stationed at 64 deg W. As of 31 August 2001 located at 64.56 deg W drifting at 0.003 deg W per day. As of 2007 Mar 10 located at 67.77W drifting at 0.049E degrees per day.

2000 November 30 - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/23. LV Family: Proton. Launch Vehicle: Proton-K/DM-2M. LV Configuration: Proton-K/DM-2M (DM3) 402-02.
  • Sirius CD Radio 3 - . Payload: CD Radio 3. Mass: 3,800 kg (8,300 lb). Nation: USA. Agency: Sirius. Manufacturer: Palo Alto. Program: Sirius. Class: Communications. Type: Civilian communications satellite. Spacecraft: FS-1300. USAF Sat Cat: 26626 . COSPAR: 2000-077A. Apogee: 47,084 km (29,256 mi). Perigee: 24,485 km (15,214 mi). Inclination: 64.2000 deg. Period: 1,436.00 min. Direct Radio Broadcasting satellite. Launch delayed from early October due to delays in delivery of engines. Stationed at 66 deg W. The third Sirius digital radio broadcast satellite was a Loral FS-1300 series vehicle and was placed in an initial elliptical 63 degree orbit by the Proton upper stage. Positioned in geosynchronous orbit at 66 deg W in 2000. As of 30 August 2001 located at 64.69 deg W drifting at 0.027 deg E per day. As of 2007 Mar 10 located at 65.64W drifting at 0.010E degrees per day.

2010 October 14 - . 18:53 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/24. LV Family: Proton. Launch Vehicle: Proton/Briz M.
  • XM-5 - . Payload: Sirius XM-5. Nation: USA. Agency: Sirius. Program: XM. Class: Communications. Type: Communications satellite. Spacecraft: FS-1300. USAF Sat Cat: 37185 . COSPAR: 2010-053A. Apogee: 35,790 km (22,230 mi). Perigee: 35,784 km (22,235 mi). Inclination: 0.1000 deg. Period: 1,436.10 min. Summary: Fifth direct-broadcast digital radio satellite in the Sirius constellation..
