Arianespace launches its latest launch in 2018 on Tuesday, using a Soyuz rocket to deploy a high-resolution satellite satellite to the French military. Soyuz expects the rise of the Guyana Space Center (Kourou, French Guiana) to rise 13:37:14 time local time (4:37 p.m.), extending the CSO-1 position one hour later.

Tuesday will launch CSO-1, Composante Spatiale Optique (CSO), or the first three satellites that make up the Optical Space Component. Spatial ships will be deployed to the French military, replacing former Helios satellite. For the construction of the constellation, the French General of the Armement Department (DGA) has co-operated the Directorate General of the Army with the CNES national space agency.

Airbus Defense and Space are three main CSO satellite contractors, based on the AstroSat-1000 platform. Each satellite has a capacity of 3.65 kilograms (7,859 kilograms) and is expected to operate at least ten years. The image system produced Thales Alenia Space. From the 800-km altitude (497 miles and 432 miles) of the solar synchronous orbit, CSO-1 will enable a resolution of 35 centimeters (14 inches) resolution.

CSO-1 is the third-generation satelite satellite of French satellites after Helios space pair. A satellite research on the French prime ministers was Helios-1A in July 1995 on the Ariane 4 rocket.

The identical Helios-1B opened in December 1999 to replace it. The second generation of Helios follows a high-resolution imaging system: Helios-2A was launched by an Ariane 5G + on December 18, 2004 and launched by Helios-2B on Ariane 5GS five years later. It is noteworthy that the CSO-1 program is planning to launch a two-year anniversary, launching Tuesday's role eleven minutes later than Helios's two funeral.

After launching three satellites, CSO will operate two 800-km orbit satellites, CSO-2 will use a smaller orbit for high definition imagery. The role of CSO-2 has been identified, the distinctive features seen by its sister satellites in the high-orbit. CSO-2 is currently aiming to launch 2020 or 2021 with a CSO-3 constellation one or two years later.

CSO-1 Paris, based on Arianespace, has launched all French satellite surveys. Arianespace uses a fleet of three types of rockets: Vega is used to launch smaller satellites, Ariane 5 has the most heavier rewards, usually satellite pairs of geo-geostation satellites and the Russian ring Soyuz fills the gap between these two vehicles. The role of Astearte will be used by Soyuz, with the Soyuz ST-A setup with the Fregat-M high stage.

Soyuz ST-A Soyuz-2-1 is based on the rocket, in conjunction with the Arianespace site, Guyana's Managed Site (CSG), around Kourou, French Guiana. Soyuz-2-1 is one of three modernized Soyuz rockets, Sergei Korolev's R-7 missiles derived from Russian (and former Soviet satellite) satelite access and from space exchange flows from the 1960s.

Soyuz-2-1 made his first suborbital test flight in 2004 and his first orbital two years later. Soyuz-U introduced the first and second stages of the previous generation, as well as the digital flight control system and other improvements. The second Soyuz-2 configuration, Soyuz-2-1b (Arianespace works through Soyuz ST-B) has renewed the third stage engine. Soyuz-2-1v is designed to carry smaller loads, but the rocket version is not used by Arianespace.

Soyuz is a rocket in three phases, although the first and second phases are firmed. For higher orbitional missions or for more complex missions, Soyuz can be used in the top step. An assignment will be used on the platform Fregat-M to enter CSO-1 in the solar synchronous orbit. Fregat is the most common type of stage in Soyuz; It is based on propulsion systems of the propane of the Soviet Union and can restart its engine several times during a long-term mission to receive the necessary orbit loads.

Tuesday will be launched in French Guiana, Soyuz. The Soyuz launch pad, Ensemble de Lancement Soyouz (ELS), was used in October 2011 to deploy a couple of Galileo satellite navigation. Including a vehicle with CSO-1 mission, six Soyuz ST-A and fourteen Soyuz ST-B rockets went to Kourou. Soyuz, a Soyuz ST-B from Kourou, successfully executed the Fregat high-level missions.

Soyuz has launched Kazakhstan Baikonur Kosmodrome and the Plesetsk and Vostochny Cosmodromes in Russia.

Arianespace dimension designation is VS20. The first and second stage engines will start up, it will last for fourteen seconds. The first stage of the Soyuz ST-A vehicle is complemented with four Booster RDR 107A motors, in the second phase, combined with a single RD-108A.

The rocket engine will generate momentum until the rocket is tightened and the T-1 countdown power is achieved. At zero, the swingarm launcher will open and Soyuz will start to climb into space.

Soketa will burn the first and second stages together for the first and fifty-four seconds. At this time, the four main stages will be switched off, as the excess oxygen venting separates their nose from the rocket separation. The name of the Korolev Cross by Separator Boosters after the rocket designer.

After separating the first stage, Soyuz continues the second stage of power for another two minutes and 49 seconds. At the end of the second phase flight, about thirty-five seconds, the payment box will be separated from the rocket nose.

They have been designed to separate the second and third stages while the second stage is still firing. The third stage starts with its RD-0110 engine, while the RD-108A is still burning, the propeller determines the tanks in the third phase. The third stage will be four minutes and two seconds before continuing the Fregat, to continue the journey to the CSO-1 orbit.

After separating the sixth second in the third phase, Fregat took the S5.98M engine to the first three planned streams. It will last for eight minutes and fifty-five seconds by setting up an initial orbital parking lot. Fregat will repopulate it again in another 89 seconds after the 34-second phase phase, circulating the orbit.

CSO-1 will separate Fregat for five minutes after his second album, within an hour and 44 seconds. Fregate retrieves its third and fourth seconds, 51 minutes later, with a 55-second maneuver that allows unbalanced stage to stop the unnecessary debris in orbit.

CSO-1 was launched at the eleventh and last of Arianespace in 2018, two pre-Soyuz missions, two Vega launches and six Ariane 5. The next Arianespace launch will be launched at the end of January, with HS4-SGS1 and GSAT-31 satellite communications satellites and Ariane 5, in the next Soyuz startup of Kup, it is expected to carry O3b satellites for the first quarter of the year.

A new Soyuz aviation is expected in Russia before the end of the year: the Soyuz-2-1 / Fregat-M vehicle opens the Vostochny Cosmodrome on August 27, detecting its first payload with a remote Kanopus-V satellite.
