Hylas-1's GFP solution works by converting the frequency of all signals received by the satellite to a common Intermediate Frequency (IF), of approximately 6 GHz. This function is performed by an electronic unit called the Agile Integrated Down-converter Assembly, (AIDA). Variants of the AIDA have been produced that cover the Ku-FSS, Ku-BSS, and Ka-bands. The AIDA shown is an engineering model serving Ku-band (FSS and BSS).
