The Square Kilometre Array telescope (SKA) is an interferometric radiotelescope, composed of hundreds of individual elements, operating between 50 MHz and 16 GHz. In the first stage (SKA1) it will consist of two instruments: SKA1-LOW, composed of 512 aperture arrays in the Australian desert, and operating between 50 and 350 MHz, and SKA1-MID, made up by 192 dishes, operating above 350 MHz in South Africa.
Since 2013 with INAF joining the SKA1-Low project with the participation to the Aperture Array Design and Construction Consortium, the radio astronomy group at the Arcetri Astrophysical Observatory has been part of the team to develop hardware&software for the Low Frequency Aperture Array (LFAA) Element of SKA. In particular the radio astronomy group at the Arcetri Astrophysical Observatory is contributing in the following areas:
Electromagnetic design, characterization and testing of the SKA1-LOW station
Design and testing of the station beamforming hardware (TPM board)
