Re:      SES Government Solutions, Inc. STA Requests to Communicate with O3b,
         File Nos. SES-STA-20131022-00887 & SES-STA-20131022-00888

Dear Ms. Dortch:

SES Government Solutions, Inc., formerly known as Americom Government Services, Inc.
(“SES-GS”), by its attorney and pursuant to Section 1.65 of the Commission’s rules, 47 C.F.R.
§ 1.65, hereby updates the record regarding the above-referenced SES-GS requests for special
temporary authority (“STA”) to operate an earth station in Bristow, VA that will communicate with
the O3b Ka-band non-geostationary orbit satellite fleet. SES-GS has reviewed the
supplemental materials O3b has filed in support of its pending applications for a fixed earth
station in Bristow 1 and for a blanket license for Earth Stations on Vessels. 2 No substantial
changes are required to the SES-GS STA requests in connection with this additional information
from O3b. SES-GS, however, wishes to update the cross-references and other information in
its STA requests as follows.

      1. In the narrative for its 180-day STA request, SES-GS recognized that terrestrial LMDS
         systems have primary status in the 28.172-28.350 GHz portion of the uplink spectrum
         O3b has assigned to SES-GS. 3 In order to ensure that the proposed SES-GS
         operations would not cause harmful interference to LMDS, SES-GS asked Comsearch
         to notify LMDS systems in the area of the planned SES-GS operations, and Comsearch

 Letter of Joslyn Read, Vice-President, Regulatory Affairs, O3b Limited, to Marlene H. Dortch,
Secretary, Federal Communications Commission, File No. SES-LIC-20130618-00516, filed

 SES Government Solutions, Inc., File No. SES-STA-20131022-00887 (“SES-GS STA”),
Narrative at 2.


Ms. Marlene H. Dortch                           -2-                           December 13, 2013


         provided a report confirming that none of the LMDS operators raised any objections. 4 In
         the O3b Bristow Supplement, O3b responded to a question regarding whether O3b’s
         planned operations at Bristow were consistent with prior Commission indications that
         secondary FSS operations in the 27.6-28.35 GHz band should be limited to gateway-like
         operations. 5

         SES-GS agrees with O3b that the focus of the Commission’s statements regarding FSS
         operations in the 27.6-28.35 GHz band has been on ensuring that such operations are
         compatible with LMDS by limiting the number and ubiquity of FSS terminals permitted to
         use the spectrum. The proposal by SES-GS to operate at a single site that is virtually
         co-located with the O3b Bristow antenna site is clearly consistent with this underlying
         rationale. Furthermore, as noted above, LMDS systems in the vicinity of the site have
         been notified of the proposed SES-GS operations and have not objected. Accordingly,
         grant of the requested SES-GS STA will not undermine the primary spectrum rights of
         LMDS systems.

      2. The SES-GS STA included an analysis of compliance with ITU uplink EPFD limits
         designed to protect primary GSO FSS networks in the 28.35-28.4 GHz band. 6 SES-GS
         referred to the O3b demonstration of compliance with these limits, which was based on
         the proposed power levels of the O3b Bristow earth station and the angular separation
         between the O3b and geostationary orbits as viewed from the Earth. In the O3b Bristow
         Supplement, O3b responded to a question from the Commission staff regarding the
         EPFD(up) limits in No. 22.5D of the ITU Radio Regulations and provided a more detailed
         demonstration of its compliance with those limits that is specific to the Bristow antenna
         site. 7

         SES-GS hereby incorporates by reference the supplemental O3b analysis on
         compliance with ITU uplink EPFD limits. The SES-GS Bristow antennas will operate at
         power levels below the levels that O3b used in its supplemental analysis. 8 Accordingly,
         the conclusion stated in the SES-GS STA Narrative that SES-GS will comply with
         applicable ITU EPFD(up) limits in the 28.35-28.4 GHz band remains valid.

  Specifically, SES-GS proposes to operate with a maximum earth station EIRP density that is
equivalent to 31.5 dBW/40kHz (SES-GS STA, Narrative at 3 n.5), while O3b is proposing to
transmit with a maximum EIRP density equivalent to 34.6 dBW/40kHz (O3b Bristow Supplement
at 1).


Ms. Marlene H. Dortch                          -3-                           December 13, 2013


      3. SES-GS incorporated by reference the O3b Schedule S and associated service area
         definition and beam contour maps. 9 O3b has since provided a revised version of these
         materials. 10 SES-GS updates its STA request to refer to the revised O3b Schedule S
         documentation.

      4. The SES-GS STA cross-references O3b’s demonstration that its system complies with
         all applicable FCC power flux density (“PFD”) limits. 11 The O3b Bristow Supplement
         confirms that the PFD levels provided in the O3b Revised Schedule S are below the
         applicable limits in the FCC rules. 12 The proposed SES-GS antennas will operate with
         O3b downlink signals that are below the maximum EIRP density used by O3b to show
         its compliance with the Commission’s PFD limits. Accordingly, the O3b showing as
         supplemented supports the conclusion that the planned SES-GS operations will be
         consistent with Commission limits as well.

SES-GS asks that the Commission update the record relating to the SES-GS STA requests as
outlined above. Apart from the foregoing items, SES-GS does not believe that the supplemental
O3b materials alter the information on which SES-GS relied in its STA requests. 13

Please let me know if you have any questions regarding this matter.

Respectfully submitted,

/s/ Karis A. Hastings
