Galileo’s Ariane 5 arrives at Europe’s Spaceport

Unloading Ariane 5

 

30 August 2016

The first Ariane 5 rocket modified to carry four Galileo satellites into orbit has arrived at Europe’s Spaceport in French Guiana for a November launch.

So far, 14 Galileo satellites have been launched two by two on Soyuz rockets from French Guiana. This inaugural launch by Ariane 5 will boost that number to 18.

The MN Colibri roll-on/roll-off ship, built to transport European rocket elements, reached French Guiana’s Pariacabo Port on 22 August.

The cargo included Ariane’s cryogenic core stage, its upper stage and payload fairing. This Ariane variant is based on the launcher previously used to place ESA’s 20 tonne Automated Transfer Vehicle supply vehicle into low orbit.

 

Transfer to Spaceport

This version has to carry a lower mass – four fully fuelled 738 kg Galileo satellites plus their dispenser – but needs to take it up to the much higher altitude of 23 222 km.

The target orbit is actually 300 km below the Galileo constellation’s final working altitude: this leaves Ariane’s upper stage in a stable ‘graveyard orbit’, while the quartet of satellites manoeuvre themselves up to their final height.

 

Upper stage being transported

The four satellites to be launched by this Ariane 5 are due to be flown to French Guiana next week from ESA’s technical centre in Noordwijk, the Netherlands.

The Galileo satellite bus is built by OHB in Bremen, Germany, with the navigation payloads coming from Surrey Satellite Technology in the UK, involving supplied from all across Europe. They are then tested in simulated launch and space conditions in Noordwijk before being accepted for launch.

About Galileo

Galileo is Europe’s civil global satellite navigation system. It will allow users worldwide to know their exact position in time and space with great precision and reliability. Once complete, the system will consist of 24 operational satellites and the ground infrastructure for the provision of positioning, navigation and timing services.

The Galileo programme is funded and owned by the EU. The European Commission has the overall responsibility for the programme, managing and overseeing the implementation of all programme activities.

Galileo’s deployment, the design and development of the new generation of systems and the technical development of infrastructure are entrusted to ESA. The definition, development and in-orbit validation phases were carried out by ESA, and co-funded by ESA and the European Commission.

The European Global Navigation Satellite System Agency (GSA) is ensuring the uptake and security of Galileo. Galileo operations and provision of services will be entrusted to the GSA from 2017.

ESA: Galileo satellites moved to pad for Friday launch

 The two Galileo satellites and their upper stage have been enclosed within their protective fairing, and moved to join the Soyuz rocket on the launch pad.

The halves of the fairing were sealed together around the satellites, their supporting dispenser and Fregat-MT upper stage on Friday, within the Upper Composite Integration Stand of building S3B of Europe’s Spaceport in French Guiana.

Yesterday, the Upper Composite was moved to the launch site, for vertical mating to its three-stage Soyuz ST-B rocket.

The 4.1 m-diameter fairing protects the satellites from the stresses of launch and flight through the bulk of the atmosphere. It will be ejected about three and a half minutes into the flight, when the upper stage reaches the top of the atmosphere.

 Soyuz VS03, the third Soyuz flight from Europe’s Spaceport in French Guiana, was transferred to the launch zone on 8 October 2012. The vehicle was rolled out horizontally on its erector from the preparation building to the launch zone and then raised into the vertical position. Soyuz VS03 will lift off on 12 October 2012. The rocket will carry two satellites of Europe’s Galileo navigation system into orbit.

 Fregat, modified to carry extra propellants, will fire for the first time about 10.5 minutes after launch, raising the satellites up to orbital velocity and their operating altitude of 23 222 km.

As it climbs, Fregat will spin slowly in ‘barbecue mode’, to keep the temperatures of the satellites even.

From launch to final deployment, when the dispenser releases the satellites sideways in opposite directions, will take three hours and 44 minutes.

The launch is scheduled for 18:15:00 GMT (20:15:00 CEST) on 12 October.

 Galileo taking shape
  This follow-up launch marks a major step for Europe’s own satellite navigation system.

Four is the minimum number of satellites needed to achieve a navigational fix on the ground, with one satellite each to measure latitude, longitude, altitude and provide a time reference.

So once this second pair of satellites has been commissioned and tested, the quartet will form a completely operational mini-constellation that will be used to validate the Galileo system.
 The performance of the satellites in space together with the worldwide ground infrastructure serving to maintain Galileo’s service accuracy will be assessed in depth, to prepare the way for the launch of further satellites and then deliver initial services by mid-decade and finally build up to full operational capability.

These two new satellites are also the first to carry search and rescue antennas to pinpoint aircraft and ships in distress as part of the international Cospas–Sarsat system.

Astronomy: Fourth Galileo satellite reaches French Guiana launch site

Hi My Friends: A VUELO DE UN QUINDE EL BLOG., The next two Galileo satellites are now in place at Europe’s Spaceport in French Guiana, being prepared for their shared launch this autumn.

The next two Galileo satellites are now in place at Europe’s Spaceport in French Guiana, being prepared for their shared launch this autumn.

The fourth Galileo satellite flight model arrived at Cayenne Airport in French Guiana on Friday 17 August, flown from the Thales Alenia Space facility in Rome aboard an Ilyushin aircraft. Cocooned inside a protective air-conditioned container, the satellite was then transported to the preparation facility at the Guiana Space Centre to join the third Galileo satellite, which arrived there 10 days earlier.

 These third and fourth Galileo ‘In-Orbit Validation’ (IOV) satellites are due to be launched aboard a Soyuz ST-B vehicle in October. These new satellites will join the first two Galileo satellites – launched last year – in medium Earth orbit at 23 222 km. This will mark a significant step in Europe’s programme because it will complete the deployment of infrastructure required for the IOV phase and will allow for the first time a computation of on-ground position based solely on Galileo satellites.

 The IOV phase is being followed by the deployment of additional satellites and ground segment as required to achieve the ‘Full Operational Capability’, leading to provision of services.

The first 22 of these FOC satellites are currently being built by OHB in Germany, responsible for the platforms and final satellite integration, and UK-based Surrey Satellite Technology Ltd, producing the payloads.

The first four Galileo IOV satellites have been built by a consortium led by EADS Astrium, Germany, with Astrium producing the platforms and Astrium UK responsible for the payloads.
