Succesful demonstration of Alphasat-Sentinel-1A laser link
News: an important milestone for the ARTES 7 EDRS programme

28 November 2014 – Marking a first in space, Sentinel-1A and Alphasat have linked up by laser stretching almost 36 000 km across space to deliver images of Earth just moments after they were captured.

 

Latest Projects

Digital test bench for fast testing of complex Payloads
18 December 2014
The objective of the study is to develop and validate a digital test bench for use during AIT and IOT for all C-band to Ku-band payloads, exploiting innovative and rapid RF test techniques to significantly reduce the overall test schedule. Furthermore extension to Ka-band payloads and RF interface using optical fiber are designed.
Antenna multi-reflectors pallet product
17 December 2014
The objective of this ARTES3-4 project is to study and to design a multi-reflectors pallet antenna. This new antenna product is envisaged to generate several coverages from one antenna structure and one single deployment. The design drivers of the product are the capability to accommodate several reflectors from 2 to 5, with different diameters varying from 1600mm to 900mm, a focal length varying from 1.9m to 3.2m. The reflector mounted on the pallet shall be able to operate in Ku and Ka frequency bands, and to realise mono beam and multibeams misions. Moreover, the pallet product shall be compatible of small launchers and several platforms like Spacebus, Eurostar and Alphabus. This antenna should be accommodated in double deployment. All these characteristics are considered to design this new product.
Ku-Band High-Power Reconfigurable Broadcast Antenna
17 December 2014
In the frame of this activity an innovative Ku-band high power reconfigurable multibeam broadcast antenna has been designed, with the development and test of a demonstrator model. The most promising payload solutions suitable to support the present application in terms of both antenna configuration and front-end architecture have been identified and investigated in detail. This extended trade-off activity led to an innovative antenna solution consisting of a Confocal antenna configuration fed by an aperiodic feed array. The designed Confocal antenna architecture, associated with sparse/aperiodic array feeding system, creates an innovative approach capable to fulfill the reconfigurable regional coverage mission in Ku-band, with full array operation and then full reconfiguration capability, full power allocation flexibility and graceful degradation, minimizing the number of controls.
OGBF
16 December 2014
The project aims at designing, developing and testing a Proof-of-Concept (PoC) Test-Bed of an On-Ground Beam-Forming (OGBF) and Multi User Detection (MUD) system to demonstrate the feasibility of such technology for space telecommunication application. The activity shall demonstrate the obtainable improvements in performances with the introduction of OGBF/MUD with respect to a conventional on-board beamforming satellite system.
Demonstration of Ultra-Thin GaAs/Ge based multi-junction solar cells
16 December 2014
Pre-development and testing of cell assembly technology based on GaAs multi-junction solar cells on 20 µm and 80 µm Ge. System level study and trade-off of the ultra-thin GaAs multi-junction solar generator.
