        Re:     Request for Special Temporary Authority
                Castle Rock, Colorado Earth Station KL92

Dear Ms. Dortch:

Intelsat License LLC (“Intelsat”) herein requests a grant of Special Temporary Authority (“STA”) 1 for
180 days, commencing April 18, 2018, to use its Castle Rock, Colorado Ku-band earth station—call
sign KL92—to provide launch and early orbit phase (“LEOP”) services for the SES-12 satellite. SES-12
is expected to be launched on April 18, 2018.2 Intelsat expects the LEOP period to last approximately
180 days.3

The SES-12 LEOP operations will be performed at the following frequencies: 13998.0 MHz, 13996.5
MHz, 13999.5 MHz, 14494.5 MHz, 14496.0 MHz, 14497.5 MHz, and 14499.0 MHz (CP) in the uplink;
and 11499.5 MHz and 11703.5 MHz (CP) in the downlink. The LEOP operations will be coordinated
with all operators of satellites that use the same frequency bands and are in the LEOP path.4 All
operators of satellites in that path will be provided with an emergency phone number where the licensee
can be reached in the event that harmful interference occurs.

The 24x7 contact information for the SES-12 LEOP mission is as follows:

Ph.:    (703) 559-7701 – East Coast Operations Center (primary)
        (310) 525-5591 – West Coast Operations Center (back-up)

Request to speak with Harry Burnham or Kevin Bell.

In further support of this request, Intelsat herewith attaches Exhibits A and B, which contain a
coordination report and waiver requests. In the extremely unlikely event that harmful interference

        Intelsat has filed its STA request, FCC Form 159, a $200.00 filing fee, and this supporting letter
electronically via the International Bureau’s Filing System (“IBFS”).
2
        The in-orbit testing location for SES-12, which Intelsat understands is licensed by the Netherlands, will
be 81.5° E.L. The final location of SES-12 will be 95.0° E.L.
3
         Intelsat is seeking authority for 180 days to accommodate the longer orbit-raising time period required for
an electric propulsion satellite.
4
        Airbus, the manager of the SES-12 LEOP mission, will handle the coordination.

should occur due to transmissions to or from its earth station, Intelsat will take all reasonable steps to
eliminate the interference.

Finally, Intelsat clarifies that during the SES-12 LEOP mission, Airbus will serve as the mission
manager. Airbus will build and send the commands to the Intelsat antenna, which will process and
execute the commands. Telemetry received by Intelsat will be forwarded to Airbus. Intelsat will
perform the ranging sessions by sending a tone to the spacecraft periodically. Intelsat will remain in
control of the baseband unit, RF equipment, and antenna.

Grant of this STA request will allow Intelsat to help launch the SES-12 satellite. This, in turn, will help
provide additional capacity from the 95.0º E.L. orbital location and thereby promotes the public interest.

Please direct any questions regarding this STA request to the undersigned at (703) 559-6949.

Respectfully submitted,


/s/ Susan H. Crandall
