24-496: A 1,500 m/s residual velocity to GSO. A tandem launch of multiple spacecraft is also supported, with the ability to inject the spacecraft into different orbits. The maiden flight of Briz-M took place on 5 July 1999. The flight was a failure, due to the explosion of the carrier rocket's second stage. The flight had a communications satellite as a payload. Briz-M completed its first successful flight on 6the June 2000, when it delivered
36-601: A time very popular with early domestic satellite television enthusiasts in Western Europe as these were among the first such signals to be receivable there. In this application, Gorizont was (except at high latitudes ) the successor to the Orbita system which used non-geostationary Molniya satellites. Gorizont represented an improvement in channel capacity and could be picked up on less elaborate receiving systems. This article about one or more communications satellites
48-451: A twin upper stage consisting of a core module (using Briz-KM as the baseline) and a jettisonable add-on toroidal tank surrounding the core. It is powered by a pump-fed gimballed main engine, the 14D30 . The main engine can be restarted 8 times in flight and allows precision placement of the spacecraft into orbit. Orbital lifetime of the Briz-M is limited by available onboard battery power and
60-446: Is a single-piece structure with a conical tank compartment and the engine located in a recess in the fuel tank. Briz-KM ( GRAU index 14S45) is an improved version of Briz-K. The Briz-K and Briz-KM were used as a third stage of the Rokot launch vehicles. Briz-M, GRAU index 14S43, is designed for injecting large payloads into a low, medium-height or high geosynchronous orbit . Briz-M is
72-409: Is currently 24 hours. The total time of the standard Proton/Briz-M mission to geosynchronous orbit profile from lift-off to spacecraft separation is approximately 9.3 hours. A Proton launch vehicle with a Briz-M upper stage can also inject payloads to Earth escape trajectories. One of system's design goals has been to keep overall dimensions as small as possible. Briz-M takes much less space on board
84-593: Is different from Wikidata All article disambiguation pages All disambiguation pages Briz-M The Briz-K , Briz-KM and Briz-M ( Russian : Бриз-К, КM and M meaning Breeze-K, KM and M ) are Russian liquid-propellant rocket orbit insertion upper stages manufactured by Khrunichev State Research and Production Space Center and used on the Proton-M and Angara A5 . The upper stages were also used on Rokot , one of Russia's smaller launchers, before its retirement in 2019. Briz-K, GRAU index 14S12,
96-494: The Gorizont communications satellite into orbit. It is planned to use Briz-M with the A3 and A5 versions of the future Angara rocket family . Gorizont Gorizont ( Russian : Горизонт , lit. ' horizon ' ), GRAU index 11F662, was a series of 35 Russian, previously Soviet , geosynchronous communications satellites launched between 1978 and 2000. The program
108-631: The 1980 Olympics, some of the surplus C-Band capacity on the satellites was used to distribute Television in the Soviet Union both to relay transmitters within the USSR (where the vast physical size of the country made conventional distribution to remote areas difficult) and to other Eastern Bloc and allied countries for relay to Soviet troops stationed there. Later programming from other Warsaw Pact countries and Cuba were added. Signals from these satellites spread well outside their intended area and were for
120-550: The Okean program. Gorizont satellites were based on the KAUR-3 satellite bus , which provided three-axis stabilisation , and liquid maneuvering engines. The Gorizont satellite constellation was replaced by the Ekspress constellation . The first satellite Gorizont-11L was launched on 19 December 1978 and the last satellite launched was Gorizont No.45L on 6 June 2000. Following
132-452: The launch vehicle compared to its predecessor, the Block D upper stage, leaving freed volume for the cargo. A Proton with a Briz-M can place a 4,385 kg satellite, such as an A2100AX , into a target orbit with an apogee of 35,786 km, a perigee of 7,030 km, and an inclination of 17.3°. Maximum lift capability of the Briz-M stage is 5,645 kg to geosynchronous transfer orbit with

#1733085632587144-559: Was started in order to develop a satellite system to relay coverage of the 1980 Olympic Games from Moscow . The first four satellites were originally launched for this sole purpose. Following this, the Gorizont system was integrated into the YeSSS Unified Satellite Communication System, and was used to relay both civilian and military communications. From 1988 onwards, the satellites were also used in support of
