GUSA Licensee LLC – Request for 180-day STA – October 21, 2010 (Clifton, TX) Page 3 of 3 Information on MLS Sites For the Clifton, Texas, Globalstar gateway site, there are four potential MLS sites, i.e., Category III airports, within the 200 nautical mile coordination distance. The Clifton site is located at 31-48-06 N, 97-36-45 W. The airports are: IAH Houston – George Bush International Airport, approximately 163 nautical miles from Clifton AUS Austin – Bergstrom International Airport, approximately 91 nautical miles away DFW Dallas/Ft. Worth International Airport, approximately 71 nautical miles away AFW Ft. Worth Alliance Field, approximately 68 nautical miles away Based on a directory used for MLS coordination purposes, and to the best of its knowledge, GUSA believes that MLS is not active at any of those sites and will not be active during the requested 180-day STA period.
