SatCom Law LLC 1317 F St. NW, Suite 400 Washington, D.C. 20004 T 202.599.0975 www.satcomlaw.com May 9, 2018 By Electronic Filing Ms. Marlene H. Dortch Secretary Federal Communications Commission 445 12th Street, S.W. Washington, D.C. 20554 Re: SES Government Solutions, Inc. Update of Earth Station Coordinates File Nos. SES-RWL-20100714-00900 et al. Dear Ms. Dortch: SES Government Solutions, Inc. (“SES-GS”), by its attorney, hereby provides updated coordinate information for several of its earth station licenses. The Commission has stated that in order to improve the accuracy of the information in the International Bureau Filing System (“IBFS”), it recommends that earth station licensees use World Geodetic System 1984 (“WGS84”) datum to specify site coordinates and has suggested that applicants for renewal or modification of earth station licenses provide coordinates based on WGS84. 1 In response to the Earth Station Accuracy Notice, SES-GS has determined WGS84 coordinates for all of its licensed earth stations and provides the information in the table below for sites with minor deviations from the coordinate data in IBFS. 2 The table also shows the elevation associated with the WGS84 coordinates. SES-GS is preparing modification applications to request correction of coordinates in cases that involve larger deviations from the IBFS license data. 1 See International Bureau Addresses Accuracy of Earth Station Location Information in IBFS, DA 17-1127, rel. Nov. 21, 2017 (“Earth Station Accuracy Notice”). 2 Specifically, the differences are less than one second in latitude/longitude for C-band operations and less than ten seconds in latitude/longitude for Ku-band operations. See 47 C.F.R. §§ 25.228(a)(4)(vi) and 25.130(g).
