Examples of Alphabus in a sentence
HuartToday at the Paris Air Show, ESA and Inmarsat moved closer to the implementation of Alphasat, the first satellite based on Alphabus, the new European telecommunications platform.Alphabus is a programme initiated by ESA and CNES to jointly develop a product through a project industrial team made of EADS Astrium and Thales Alenia Space.
The necessary increase of the mass on board telecommunications satellites (e.g. Alphabus platform25), enabled by the increase of the payload carried by the launchers, requires high power HETs. Several 5 to 10 kW-class HETs have been manufactured and life-tested worldwide to be employed for North/South station keeping for such heavy-mass satellites (namely the NASA-173M in United States26, the SPT-140 in Russia27, and the PPS®X000 in Western Europe28).
In many cases these can draw on equivalent documentation generated in the frame of the Alphabus development.
The thermal vacuum campaign has been followed by a complete EMC test campaign including different LISN configurations to cover the SB4000, E3000 and Alphabus platforms.
Alphabus is a new-generation high-power large-platform programme launched by CNES with industrial cooperation from Alcatel Space Industries and Astrium.
In the frame of the Alphabus development a clear preference for parts and equipment originating from European or Canadian sources has been applied.
This Inmarsat mission definition is based around multimedia mobile services already provided by the current Inmarsat IV satellites through BroadbandImplementation of this Geo-mobile application will use the Alphabus platform design in a configuration that requires a 90 degree change to the satellite flight orientation to improve accommodation of the feed/reflector configuration and allow the embarkation of a large deployable reflector.
Our findings revealed two space projects that corresponded to a bilateral contract-based coopetition: Yahsat and Alphabus.
Separated Project Teams vs Coopetitive Project Teams Yahsat and Alphabus were the most important space projects in the decade.
Where necessary analyses shall extend those performed in the frame of the Alphabus activities.
