Re:    Gogo LLC Section 1.65 Letter
       File No. SES-MFS-20151022-00735, Call Sign E120106

Dear Ms. Dortch:

Gogo LLC (“Gogo”), by its attorney and pursuant to Section 1.65 of the Commission’s rules,
47 C.F.R. § 1.65, hereby updates the above-referenced application to modify Gogo’s license for
Earth Stations Aboard Aircraft (“ESAA”), which sought to add a number of satellites to the Gogo
ESAA network (the “Gogo Modification”). Specifically, this letter provides corrections or
clarifications regarding orbital debris mitigation matters for Yamal 300K and Yamal 401,
technical parameters and market access issues relating to Yamal 300K, identification of
satellites and administrations, and certain technical data. In addition, Gogo requests that the
Commission hold in abeyance its request for authority to communicate with the AMC-1 satellite
pending further developments.

                    Yamal Spacecraft Orbital Debris Mitigation Statements

The Gogo Modification sought authority to add the Yamal 300K and Yamal 401 satellites as
authorized points of communication. In support of its requests, Gogo provided orbital debris
                                                  1
mitigation statements relating to both spacecraft. Subsequent to submitting the modification
application, Gogo has had further discussions with Gazprom, the satellites’ operator, and
provides corrections and clarifications regarding these statements.

First, Gazprom has revised the tables regarding the residual propellant and pressurant that will
be on board each spacecraft at its end of life. The updated tables are below and should replace
the tables in Annexes 5.4.C and 5.4.D. In each table, the information that has changed from
what was presented in the Gogo Modification is indicated by red, bold text.

In addition, Gazprom has confirmed that the residual pressure data presented for each
spacecraft in the tables above assumes a temperature of 293K.

                      Yamal 300K Market Access and Operational Information

Gogo updates and corrects the information provided with respect to its proposed use of the
Yamal 300K satellite as follows:

      •   Gogo proposes to use the beam on Yamal 300K designated “Northern Beam 1.” That
          beam provides coverage over certain parts of U.S. territory and adjacent territorial
          waters, and accordingly Gogo seeks Commission authority to use the satellite in U.S.
          airspace. Furthermore, Gogo deletes its request to use the 12.5-12.75 GHz band for
          downlinks from Yamal 300K because this spectrum is not used by Northern Beam 1. A
          revised copy of Annex 2 to the Gogo Modification reflecting these changes is attached.

      •   Subsequent to submission of the Gogo Modification, Panasonic filed a request for U.S.
          market access for the Yamal 300K satellite, including submission of a Schedule S and
                                         2
          detailed technical information. Gogo similarly requests U.S. market access for
          Yamal 300K and incorporates by reference the materials supplied in the Panasonic
          Amendment. Gogo also seeks any necessary waiver of Section 25.210(f) of the
          Commission’s Rules, 47 C.F.R. § 25.210(f). As discussed in the Panasonic
          Amendment, although the Yamal 300K satellite does not satisfy Commission
          requirements for full frequency reuse in the Ku-band spectrum that will be used for
          ESAA operations, Commission precedent supports grant of a waiver to permit U.S.-
          licensed earth stations to communicate with satellite capacity that would otherwise lay
                    3
          dormant.

                            Identification of Satellites and Administrations

Gogo also provides the following information to correct certain data that was provided in items
E21-E24 of the Schedule B filed with the Gogo Modification.

In addition, Gogo notes that the correct licensing administration for the Eutelsat 117 West A
satellite is Mexico.

                              Corrections to Form 312 and Schedule B

Gogo has also completed a thorough review of the data submitted with the Gogo Modification
and updates the Form 312 and Schedule B submitted with the application as follows:

      •   In response to item 20 of the Form 312, Gogo specifies that the nature of service should
          be Fixed Satellite (box a), as ESAA is an application of the fixed-satellite service.

      •   The response to item E38 of the Form 312 Schedule B was incorrect for the AES1
          terminal and should be changed to 35.48 Watts.

                                             AMC-1 Satellite

Finally, Gogo asks the Commission to defer action on the request in the Gogo Modification for
authority to communicate with the AMC-1 satellite pursuant to the regulatory framework set forth
in Section 25.227(a)(1) and (b)(1). In its application, Gogo noted that because AMC-1 had only
recently been relocated to its position at 129.15° W.L., efforts to coordinate the satellite with
operations of adjacent spacecraft had not yet been completed. As a result, Gogo was not in a
position to provide a letter confirming that operation of the Gogo ESAA terminals using AMC-1
was consistent with coordination agreements with satellites operated within six degrees of the
                         4
AMC-1 orbital location.

Pending completion of coordination efforts, Gogo proposed to operate its terminals with
technical parameters that comply with the off-axis EIRP spectral density specified in

    See Gogo Modification, Narrative at 3.


Ms. Marlene H. Dortch                         -5-                               February 4, 2016

                                                                                     5
Section 25.227(a)(1)(i)(A) in the plane of the geostationary satellite orbit (“GSO”). Gogo
requested any necessary waiver of Section 25.227(a)(1)(i)(B) relating to the off-axis EIRP
                                                                                       6
spectral density of the Gogo antennas in directions other than along the GSO plane.

Subsequent to filing of the Gogo Modification, efforts to coordinate Gogo ESAA operations
using AMC-1 with adjacent satellites have continued. Once a coordination agreement has been
finalized, Gogo expects to be able to update the Gogo Modification by supplying the
coordination letter required pursuant to the regulatory framework set forth in
Section 25.227(a)(2) and (b)(2). That will make the request in the Gogo Modification application
for AMC-1 authority under the Section 25.227(a)(1) and (b)(1) framework moot.

Accordingly, Gogo believes that the most efficient approach would be for the Commission to
suspend processing of the AMC-1 request in the Gogo Modification and hold that request in
abeyance. Gogo asks that the Commission proceed with processing of the remainder of the
Gogo Modification, as the other satellites discussed in the application have all been coordinated
and therefore do not present the same issues as AMC-1.

                                             *****

Gogo requests that the Commission update its records regarding the Gogo Modification to take
the above information into account and seeks expeditious processing of the Gogo Modification
with these updates. Please let me know if you have any questions regarding this matter.
