It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur.

Proton/Briz K/M Chronology


1999 July 5 - . 13:32 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/24. LV Family: Proton. Launch Vehicle: Proton/Briz K/M. LV Configuration: Proton-K/Briz-M 389-01. FAILURE: Second stage explosion.. Failed Stage: 2.
  • Raduga - . Payload: Raduga s/n 45L. Nation: Russia. Agency: RVSN. Class: Communications. Type: Military communications satellite. Spacecraft: Raduga. COSPAR: F990705A. Apogee: 30 km (18 mi). Carried a Russian Defence Ministry communications satellite. First attempted flight of the Khrunichev Briz-M upper stage in place of the usual Block DM. After the second stage explosion the remainder of the vehicle survived for 45 seconds before breaking up. Debris landed near Karaganda. As a result of this accident the Kazakh government suspended launches from Baikonur pending Russian agreement to pay back part of rent owed.

2000 June 6 - . 02:59 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/24. LV Family: Proton. Launch Vehicle: Proton/Briz K/M. LV Configuration: Proton-K/Briz-M 392-01.
  • Gorizont - . Payload: Gorizont 45. Mass: 2,125 kg (4,684 lb). Nation: Russia. Agency: Svyaz. Manufacturer: Reshetnev. Class: Communications. Type: Civilian communications satellite. Spacecraft: Gorizont. Completed Operations Date: 2000-06-06 . USAF Sat Cat: 26372 . COSPAR: 2000-029A. Apogee: 35,798 km (22,243 mi). Perigee: 35,779 km (22,231 mi). Inclination: 0.3000 deg. Period: 1,436.20 min. Communications satellite. First successful Proton/Briz-M launch. The Proton placed the Briz-M/Gorizont payload stack into a suborbital trajectory. The stage then performed four maneuvers to put the satellite into geosynchronous orbit:
    • Burn 1 placed the stack into a 200 km, 51.6 deg parking orbit probably inclined at around 51.6
    • Burn 2 raised apogee to 6000 km and changed inclination slightly
    • Burn 3, at second perigee, four hours after launch put the stack in a 369 x 34,988 km x 48.8 deg transfer orbit. The Briz-M then jettisoned its empty toroidal supplementary fuel tank.
    • Burn 4, ten hours after launch, placed Gorizont No. 45L in near-geostationary orbit.

    Gorizont No. 45L was expected to be the final launch of that model of television broadcasting satellite. It carried 6 C-band transponders, one L-band, and one Ku-band transponder. The newer Ekspress satellites are replacing the system. Stationed at 145 deg E. Positioned in geosynchronous orbit at 145 deg E in 2000. As of 5 September 2001 located at 145.25 deg E drifting at 0.002 deg W per day. As of 2007 Mar 10 located at 144.69E drifting at 0.019W degrees per day.
