> On December 20, 2011, LightSquared Inc. (LightSquared) filed a Petition for Declaratory Ruling (Petition), requesting that the Commission “resolve the regulatory status” of commercial Global Positioning System (GPS) receivers, to the extent their operations may be impaired by the ancillary terrestrial component (ATC) of LightSquared’s licensed operations in the 1524-1559 MHz Mobile-Satellite Service (MSS) band.1 To this end, LightSquared requests specific declarations designed to establish that commercial GPS devices are not entitled to interference protection from LightSquared’s operations, so long as LightSquared operates within the technical parameters prescribed by rule and Commission Order.2 Pursuant to Rule 1.2(b), we invite comment on LightSquared’s petition, and establish a pleading cycle.
> On January 26, 2011, the International Bureau granted LightSquared Subsidiary LLC (a subsidiary of LightSquared Inc., hereinafter also referred to as LightSquared) a conditional waiver of the ATC “integrated service” rule, thereby establishing certain conditions that LightSquared must meet before it can provide the terrestrial portion of service contemplated by its proposed integrated satellite and terrestrial 4G wireless network.3 The Conditional Waiver Order prescribed an Interference-Resolution Process by which LightSquared would work with the GPS community to resolve concerns raised about potential interference to GPS receivers and devices that might result from LightSquared’s planned terrestrial operations. As a condition of commencing such commercial operations, the Conditional Waiver Order required that this process first be “completed,” a term defined as the point at which “the Commission, after consultation with

Looks like comments on interference resolution should be filed on
Docket No. 11-109.

More general comments on FCC regulations related to GPS filed on
Docket No. 10-142.

Need to pick the right one when filling in the comment form at the

" . . . Further, because we believe the ongoing Interference-
Resolution Process provides the most appropriate forum for considering
LightSquared’s satisfaction of the interference-resolution conditions
of the Conditional Waiver Order, we associate LightSquared’s Petition
with the docket established by the Commission for petitions for
reconsideration of the Conditional Waiver Order, IB Docket No.
11-109. To the extent the Petition raises general issues about the
regulatory status of GPS devices, these issues will be considered in
ET Docket No. 10-142."

responsibility for resolving interference issues with MSS ATC
providers like LightSquared.8"
