Dear Ms. Dortch:

Intelsat License LLC ("Intelsat") herein requests a grant of Special Temporary Authority ("STA")‘ for
60 days, commencing August 10, 2017, to use its Hagerstown, Maryland C—band earth station—call sign
KA275—to provide Telemetry, Tracking, and Command ("TT&C") services to Intelsat 35e (call sign
$2959) at its permanent location of 34.5° W.L.* Intelsat has a pending application to permanently
modify its KA275 license to support Intelsat 35e TT&C services at 34.5° W.L.*

The proposed operations will be performed at the following center frequencies: 4197.75 MHz, 4198.25
MHz, 4198.75 MHz, and 4199.25 MHz (space—to—Earth); and 5853.0 MHz and 6424.5 MHz (Earth—to—
space).

In further support of this request, Intelsat incorporates its pending modification application," which
includes technical information that demonstrates that the operation of the earth station will be
compatible with its electromagnetic environment and will not cause harmfulinterference into any
lawfully operating terrestrial facility.

The proposed operations at 34.5° W.L. will be consistent with Intelsat‘s coordination agreements for the
nominal 34.5° W.L. In the unlikely event that harmful interference occurs, Intelsat will take all
necessary steps to eliminate the interference.


‘ Intelsat has filed its STA request, an FCC Form 159, a $200.00 filing fee, and this supporting letter
electronically via the International Bureau‘s Filing System ("IBFS").
