File # 0469-EX-CN-2017 University of North Carolina at Wilmington Center for Marine Science SOCON Project FOR REFERENCE ONLY As required by the Commission, the following technical parameters are provided for SeaHawk-1 and SeaHawk-2 communications with an earth station operated outside the United States, its territories and possessions as well as earth stations licensed to an entity other than the University of North Carolina at Wilmington Center for Marine Science (“UNCW/CMS”). The SeaHawk satellites are authorized to access the Clyde Space TT&C ground station in Glasgow, Scotland. Clyde Space has contracted with KSAT in Svalbard, Norway for access to the SeaHawk satellites for launch and early commissioning, as well as emergency backup and maintenance. UNCW/CMS will maintain the same operational constraints of its FCC license in which UNCW maintains operational control of the satellite.
