Re:        SES Americom, Inc. Update of Earth Station Coordinates
           File Nos. SES-RWL-20190315-00376 et al.

Dear Ms. Dortch:

SES Americom, Inc. (“SES”), files this letter pursuant to Section 1.65 of the rules of the Federal
Communications Commission (“FCC” or “Commission”) with respect to the continuing accuracy and
completeness of information furnished in its current earth station licenses.1 SES 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 WGS84.2

In response to the Earth Station Accuracy Notice, SES has determined WGS84 coordinates for all of its
licensed earth stations and provides the information in the table below. The table also shows the
elevation associated with the WGS84 coordinates.
