‘WICHO’”/> J. PEDREIRA ‘WICHO’ Everything is prepared in Kourou Spaceport for Ariane launch 5ECA that satellites will orbit Alphasat I-XL and INSAT-3D , scheduled for a window that goes from the 21: 53 to 23:11 of July 25, 2013.
The Alphasat I-XL is a satellite communications company Inmarsat that will serve to increase the capacity of its global network of voice and data, Specifically in Europe, Asia, Africa and the Middle East given the orbital position to be filled.
A standard chassis
But what is special about the Alphasat I-XL is that it is the first satellite based platform Alphabus communications satellite developed by the European Space Agency (ESA).
The idea is to offer companies that need to launch a communications satellite a starting point that allows them to avoid having to design everything from scratch .
It is, saving all distances, as when a truck manufacturer offers a specific chassis on which body builders and other manufacturers install the equipment needed to suit the needs of each of its customers.
In the case Alphabus of which provides a chassis which can be fitted with chemical or electrical motors customer chooses according to a power generation system with electrical panels 4 to 6 meters and associated battery systems attitude control and an internal connection system for equipment to be mounted by the client.
These can be up to 200 high-power transmitters and their associated antennas, equivalent maximum transmission capacity about 1,000 and 200,000 television channel sound.
estimated duration of a satellite service platform based on Alphabus is about 15 years.
Spanish Participation class=”ladillo”>
Although EADS Astrium and Thales Alenia Space is the prime contractor for this new platform also includes technology Spanish , because the company Crisa has designed and manufactured three teams that are part of this.
One of them is responsible for the control electronics of the various pyrotechnic devices which act during the early stages of the satellite into orbit to deploy solar panels and antennas.
Another is the thermal control electronics platform, which includes temperature control sensors and control of the heaters which are adapted to the temperature of the platform depending on the environmental requirements to keep always within the required range and are fried or freezing equipment on board.
Finally, the third team is developed by Crisa electronics power protection, which is responsible to avoid possible power failures caused by satellite other units connected to the electrical system.
An Indian passenger and other experiments
Alphasat I-XL has also aboard four technology demonstrators, environmental testing sensor and Efacec radiation (Portugal), the Q-band experiment / V Aldo Paraboni of Thales Alenia Space and Space Engineering (Italy), the advanced sensor-Optronik stars Jena (Germany), and advanced terminal TESAT optical communications (Germany), provided by the German Aerospace Center DLR.
By Meanwhile INSAT-3D, which takes advantage of the dual launch capability 5ECA Ariane is a weather satellite also incorporates the data relay capability for search and rescue satellite-aided.
