Soyuz-ST at Guiana Space Center

Voir l’information en français

Intergovernmental agreement about long-term cooperation in the field of launcher development, production and implementation as well as building of launching pad for Soyuz-ST at Guiana Space Center (French Guiana) was signed between presidents of Russian federation and France in November 7, 2003


GSC (Guiana Space Center), known as Kourou European spaceport, located at Northeastern coast of South America, will provide optimal conditions to perform commercial launches.

Spaceport function:

• Launch of satellites to sun-synchronous orbits;

• Simultaneous launch of a single satellite or satellites cluster to low-earth orbit;

• Launch of satellites to medium-earth orbit;

• Launch of research satellites to various orbits;

• Launch of small satellites with piggy-back Payload.

The decision to build launching pad at French Guiana is based on energy conservation of spacecrafts while placing them into polar and equatorial orbits, as well as on availability of seaport and airfield (ease of transportation of launcher blocks and spacecraft), closeness of equator and flight stability.

Equatorial location of the spaceport enables increased lifting capacity of the launcher with reduced fuel consumption. Due to the difference in inclination of transfer orbits, the launcher is able to place into GTO satellites with mass significantly greater than of those launched from the Baikonur cosmodrome.

Main project participants

The Russian Party is represented by:

Roskosmos - is a prime contractor of the project from the Russian party responsible for project management, organization and coordination of all Russian enterprises activities;

JSC SRC-Progress - is a parent organization on development, production and operation of Soyuz-ST to be launched from GSC;

NPO-L - is a prime developer of Fregat, responsible for Fregat maintenance implemented into Soyuz-ST;

TsENKI - is a prime developer of Russian equipment dedicated to launching pad.

The European Party is represented by:

French National Space Agency (CNES) – performs management of works at GSC

European Space Agency (ESA) – finances project;

«Arianespace» - us one of the major world provider of space launches;

«Starsem» - Russian-French joint stock company which represents TsSKB-Progress interests on the world market of launching services.

Soyuz-ST launcher

A new spaceport will be used for launches of middle-class Soyuz-ST.

Soyuz-ST is a modification of Soyuz-2 which meet safety, TM and operating conditions requirements of European partners.
Soyuz-ST is equipped with a large-size fairing (4,11m in diameter), more powerful engines and new digital control system to control flight trajectory more precisely. It is supposed to use two types of Soyuz-ST: 1a and 1b.

Energy capability of Soyuz-ST

Launcher

GTO (∆V=1500 m/s)

Sun-synchronous orbit (Нкр=820 km)

Soyuz-ST-a

2810 kg

4230 kg

Soyuz-ST-b

3250 kg

4900 kg

Hardware implemented onboard the launcher enables engines cut-off from the ground station, i.e. in case of necessity it is possible to abort the launcher flight manually. In addition, the launcher is equipped with radar responders to control the launcher orientation during the flight. To adapt the launcher to French Guiana climatic conditions same activities have been performed.

Spaceport objects

Main objects to perform launches of Soyuz from GSC are the following:

• Technical facility of the launcher and upper stage (has been constructed recently);

• Control center (has been constructed recently);

• Launching pad (has been constructed recently);

• Mobile service tower (has been constructed recently);

• Technical facility of Upper composite (existing facility has been used);

• Measuring facility (existing facility has been used);

• Objects of supplying infrastructure (existing infrastructure has been used with minor modification as well as development of new objects).

Preparation order of Soyuz-ST

Operative preparation procedure of Soyuz-ST differs from conventional one performed at Russian cosmodromes and composed of the following steps:

· Transportation of launcher blocks and fuel from manufacturing plants to the seaport of Saint-Petersburg by rail;

· Transportation of launcher blocks and fuelto French Guiana by sea;

· Transportation of launcher blocks to the storage area of Soyuz launching pad by road transport;

· Integration of the launcher three stages, launcher transportation in horizontal position and placing at the launching pad;

· Integration of upper composite in vertical position and transportation to the launching pad;

· Mating of upper composite with the launcher in vertical position at the launching pad;

Soyuz-ST integration is performed at Assembly and testing facility (MIK), but integration of upper composite is performed at Ariane’s launching pad. Special feature of integration at GSC is mating of the launcher with upper composite in vertical position.

According to the project no less than 50 launches of Soyuz-ST have to be performed from GSC for the following 15 years. It is planned to perform from 2 to 4 launches each year.
After the launch, Soyuz will be the first carrier which is possible to launch from 3 countries: Russia (Plesetsk cosmodrome), Kazakhstan (Baikonur cosmodrome) and French Guiana (Kourou spaceport).
