                   REQUEST FOR SPECIAL TEMPORARY AUTHORITY


        Telesat Canada (“Telesat”), pursuant to Section 25.120 of the Commission’s rules,
hereby requests an extension of Special Temporary Authority (“STA”),1 for a period of
one hundred and eighty (180) days, to operate two earth stations - one located in
Pompano Beach, Florida and the other located in Melbourne, Florida - to conduct loop-
back tests with Telesat’s non-geostationary orbit (“NGSO”) low earth orbit satellite,
LEO 1.
        LEO 1 was launched in January 2018 and is currently in its final mission orbit of
99.5° (circular) at an altitude of 1000 km. Telesat seeks to continue to operate pursuant
to its STA and in accordance with the technical parameters that were specified in
Telesat’s Petition for Declaratory Ruling to Grant Access to the U.S. Market for Telesat’s
NGSO Constellation (“PDR”), including Schedule S thereto, which was granted by the
Commission by Order and Declaratory Ruling, released November 3, 2017.2 STA
operations will be limited to two of the bands covered by the PDR, i.e., 28.6-29.1 GHz
(Earth-to-space) and 18.8-19.3 GHz (space-to-Earth), which the Commission’s Ka-band
plan allocates on a primary basis to NGSO operations.
        Operations pursuant to the original STA have provided valuable information,
and Telesat seeks additional time to test, validate, and demonstrate certain design
features of LEO-1, including antenna tracking, RF performance, and end-to-end
network performance. These continued operations will set the stage for providing
highly innovative broadband services in the United States. Grant of Telesat’s STA
request, therefore, is in the public interest.
        Telesat’s original application included a detailed orbital debris assessment report
prepared by NXTRAC for LEO 1, confirming compliance with U.S. government orbit

Telesat Canada                                                                                       Attachment 1



lifetime and orbital debris mitigation regulations. It also included a radiation hazard
study for each earth station. Both reports are incorporated herein by reference.3
         As indicated above and in Telesat’s original request, operations are limited to the
portions of the Ka-band in which NGSO operations have primary status. Accordingly,
EPFD limits are inapplicable. Telesat has completed coordination of its extended STA
operations with the U.S. federal government under footnote US3344 of the United States
Table of Frequency Allocations.5 Telesat will share ephemeris data in accordance with
Section 25.146(e) of the Commission’s rules. With regard to matters of physical
coordination, there are no operators using similar orbits.
         Accordingly, for good cause as shown herein, Telesat requests extension of its
STA request.

  See note 1 at Attachment 2 and 3.

  Telesat continues to discuss the applicability of US334 with the Commission and is coordinating with the federal
government out of an abundance of caution.
5
  Telesat notes that it answered question E18 in the Schedule B provided in Attachment 2a and 2b of its original
request as “No” (i.e., that frequency coordination is not required) based on its understanding that the question relates
to non-federal government coordination requirements, if any.
