COMMENTS OF IRIDIUM CONSTELLATION LLC

Iridium Constellation LLC (“Iridium”) hereby comments on the above-captioned

applications filed by DIRECTV Enterprises, LLC (“DIRECTV”). Iridium has no

objection to a grant of the applications, but is filing these comments to clarify certain

matters.

-2-

In its applications, DIRECTV seeks authority to add “ALSAT” as a point of

communication for its above-referenced earth stations, which are at various locations.

The earth stations operate on Ka-band frequencies, including the 29.25-29.3 GHz sub-

band. DIRECTV operates Ka-band geostationary orbit satellites (“GSO”) with which its

earth stations communicate. Iridium operates a constellation of non-geostationary orbit

(“NGSO”) satellites that use Ka-band frequencies, including the 29.25-29.3 GHz sub-

band, for feeder links.

Pursuant to the Commission’s requirements for the shared 29.25-29.5 GHz band, 1

DIRECTV provided the same exhibit with each of its applications. In the exhibit,

DIRECTV concludes that its proposed earth station transmissions will not cause

unacceptable interference to Iridium’s feeder links. One of the bases for this conclusion

is the similarity between the Ka-band earth station antennas that are the subject of the

above-referenced applications and the Ka-band earth station antennas for which

DIRECTV was granted licenses in 2011.

Iridium previously filed comments concerning DIRECTV’s 2011 applications. In

its 2011 comments, Iridium stated that it had no objection to a grant of DIRECTV’s

applications but took issue with elements of the methodology DIRECTV used in

analyzing the potential for interference to Iridium’s feeder links. 2 Iridium continues to

have these methodological concerns, and is filing these comments because it does not

1See Section 25.203(k) of the Commission’s rules, 47 C.F.R. § 25.203(k).

MFS-20111104-01324 (Dec. 16, 2011).

wish its lack of objection to DIRECTV’s latest applications to be viewed as an

endorsement of all elements of DIRECTV’s methodology.

Iridium also notes that Section 25.258(a) of the Commission’s rules requires

coordination between operators of GSO FSS earth stations and NGSO MSS feeder links

using frequencies in the 29.25-29.5 GHz band. In light of the analysis provided by

DIRECTV, Iridium believes there should be no impediment to a successful coordination

in this matter. Iridium reserves the right, however, to seek relief should the outcome of

its coordination with DIRECTV, or the outcome of any future coordination, prove

unsatisfactory.

Respectfully submitted,
