To carry out sharing and compatibility studies between NGSO FSS systemsnot yet considered under ECC Report 271 and existing services in the bands and adjacent to the bands 10.7-12.75 GHz and 14 - 14.5 GHz When examining compatibility issues arising from out of band emissions, aggregate impact on existing passive services,namely RAS and EESS (passive) systems operating in the band 10.6-10.7 GHz, from FSS interference sources, including GSO satellite networks would need to be studied.
