GUSA Licensee LLC – 60-day Request for STA – January 28, 2011 (Wasilla, AK) Page 4 of 4 Information on Microwave Landing System (MLS) Sites For the Wasilla, Alaska, Globalstar gateway site, there are four potential MLS sites, including two Category III airports (ANC & FAI), within the 213 nautical mile transmit coordination distance. The Wasilla site is located at 61-35-25 N, 149-29-06 W. The airports are: ANC Ted Stevens Anchorage International Airport, approximately 29 nautical miles from Wasilla VDZ Valdez Airport, approximately 97 nautical miles away HOM Homer Airport, approximately 131 nautical miles away FAI Fairbanks International Airport, approximately 199 nautical miles away Only the ANC airport falls within the 39.8 nautical mile maximum trigger distance for MLS/MSS (Mobile Satellite System) coordination. Based on a directory used for MLS coordination purposes, and to the best of its knowledge, Globalstar USA, LLC, believes that MLS is not active at ANC.
