                       REQUEST FOR SPECIAL TEMPORARY AUTHORITY

                  SES Americom, Inc. (“SES”) respectfully requests Special Temporary Authority

(“STA”) to use its E170138 earth station located in its Woodbine, Maryland teleport 1 to

communicate with SES-15 at 137° W.L. in order to (1) provide telemetry, tracking and command

(TT&C) services for the satellite while it is located at 137° W.L. for in-orbit testing (“IOT”) and

(2) provide TT&C during the satellite’s drift to its final orbital location, 129.15° W.L. Authority

is sought for a period of up to 30 days, commencing on or around November 19, 2017. SES

requests authority for the earth station to communicate with the Gibraltar-licensed SES-15

satellite to provide TT&C services.

                  SES Satellites (Gibraltar) Limited received market access to provide service into

the United States from 129.15° W.L. using the Ku- and Ka-bands as well as to operate the

WAAS payload in the L- and conventional and extended C-bands. 2 SES-15 was launched on

May 18, 2017 and is currently en route to its test orbital location at 137° W.L. SES-15 will be

located at 137° W.L. +/-0.1 degrees during IOT. The proposed stationkeeping volume will not

overlap with any other satellite. SES seeks earth station STA to provide TT&C while SES-15 is

located at 137° W.L. and as it drifts to 129.15° W.L. using the following frequencies:

    10700.5 MHz and 12199.5 MHz                      Telemetry

    13999 MHz, 3 14001 MHz and 14499 MHz             Command


As discussed below, performing IOT while SES-15 is at 137° W.L. rather than at 129.15° W.L.

will permit testing to occur without disruption to existing customers at 129.15° W.L. and will not

adversely affect the operation of any adjacent satellites.

               Grant of STA Will Serve the Public Interest. Grant of SES’s request to provide

TT&C for the satellite during testing and drift is in the public interest. By testing SES-15 at this

location, SES will minimize the risk of interference to other satellites operating at the nominal

129° W.L. orbital location. Testing will allow SES to ensure that the satellite’s communications

payload is fully operational at the time it arrives at its final orbital location, thereby avoiding any

interruption in service that otherwise might be associated with spacecraft testing. Additionally,

STA to provide TT&C will ensure safe satellite operations during the testing and drift

operations.

               No Harmful Interference to Other Spacecraft. Testing the SES-15 Ku-band

payload at 137° W.L. will not cause harmful interference to the operations of any other

spacecraft due to orbital angular separation, frequency diversity and/or geographically diverse

beam coverage. Except for SES’s AMC-4 spacecraft, there are no satellites within +/- 6 degrees

 SES Satellites (Gibraltar) Limited was granted a waiver of Section 25.202(g) to conduct
command operations using the 13999 MHz frequency. See id., Attachment to Grant at 3,
Condition 6.
                                                                                                      2


of 137° W.L. operating in the Ku-band. SES will manage the operations of its satellites to

prevent interference.

                No Harmful Interference to Terrestrial Services. A detailed description of the

TT&C operations is provided in Attachment 1. SES will conduct all operations on a non-

harmful interference basis and will cease transmissions promptly in the event SES receives a

complaint of harmful interference regarding its operations.

                Waiver Requests. SES seeks any necessary waiver of footnote NG52 in order to

conduct domestic operations in the extended Ku-band downlink spectrum in order to receive

telemetry from the satellite and SES seeks any necessary waiver of Section 25.210(j) of the

Commission’s rules in order to permit communications with SES-15 at 137° W.L. with an east-

west stationkeeping tolerance of +/- 0.1 degree during the IOT operations. Grant of these

waivers is consistent with Commission policy:

                        The Commission may waive a rule for good cause shown.
                        Waiver is appropriate if special circumstances warrant a
                        deviation from the general rule and such deviation would
                        better serve the public interest than would strict adherence
                        to the general rule. Generally, the Commission may grant a
                        waiver of its rules in a particular case if the relief requested
                        would not undermine the policy objective of the rule in
                        question and would otherwise serve the public interest. 4


                Section 2.106 Footnote NG52. SES seeks a waiver of footnote NG52 to permit

the reception of U.S. domestic services in the 10700.5 MHz frequency on an unprotected, non-

interference basis. The Commission has granted a waiver for SES-15 to provide domestic

service in these bands. 5 Footnote NG52 was intended to preserve access to the 10.7-11.7 GHz

    SES-15 Grant, Attachment at 2, Condition 3.
                                                                                                 3


spectrum for terrestrial fixed service (“FS”) stations by limiting FSS use of the band to

international operations only. 6 SES-15 will meet the power flux density limits on the ground to

protect FS operations, and the number of antennas that will be used to communicate in these

bands will be limited, thereby ensuring protection of FS services. Moreover, because SES seeks

authority to receive in this spectrum on an unprotected basis, FS use of the band will not be

constrained. Therefore, grant of the requested waiver will not undermine the purpose of the rule.

                 Section 25.210(j): Section 25.210(j) specifies that geostationary space stations

“must be maintained within 0.05° of their assigned orbital location in the east/west direction,

unless specifically authorized by the Commission to operate with a different longitudinal

tolerance.” 7 Here, SES is seeking authority to communicate with SES-15 while the satellite is

maintained with a +/- 0.1 degree stationkeeping tolerance during the limited period of IOT

operations. The relaxed stationkeeping tolerance will minimize interruptions to the payload

testing operations due to stationkeeping maneuvers, which would delay the satellite’s on-station

start of operations. It will also conserve fuel for future satellite operations. Furthermore, the

SES-15 stationkeeping volume will not overlap with that of other satellites near 137° W.L. and

therefore there will be no adverse effect on the operations of other spacecraft.

                 Protective Conditions. SES will coordinate its test and TT&C operations with all

potentially affected operating satellite networks and will operate only the Ku-band TT&C

payload of the SES-15 spacecraft during satellite drift. All testing will be conducted on an

unprotected, non-harmful interference basis, and SES operations will cease immediately upon

notification of harmful interference. 8

                 SES hereby certifies that no party to this application is subject to a denial of

benefits pursuant to Section 5301 of the Anti-Drug Abuse Act of 1988, 21 U.S.C. § 862.

                 For the foregoing reasons, SES respectfully requests special temporary authority

to operate its E170138 earth station to provide TT&C for the SES-15 spacecraft during IOT and

drift for a period of up to 30 days commencing on or around November 19, 2017. Grant of the

requested authority will permit testing of the spacecraft without affecting services to customers

and will permit a seamless transition of services.
