Telesat 1601 Telesat Court July 7, 2017 Otttawa, CANADA K1B 5P4 FILED ELECTRONICALLY VIA IBFS Mr. Jose P. Albuquerque Chief, Satellite Division- International Bureau Federal Communications Commission 445 12th Street, S.W. Washington, DC 20554 Re: Telesat Canada, Petition for Declaratory Ruling Requesting Access to the U.S. Market for Its Non-Geostationary Orbit Constellation, Call Sign S2976 IBFS File No. SAT-PDR-20161115-00108 Dear Mr. Albuquerque: It has come to the attention of Telesat Canada (“Telesat”) that there were two typographical errors in the Schedule S that it submitted in connection with the above- referenced application. These errors are described and corrected below: The Right Ascension of Ascending Node (RAAN) values for Telesat’s five inclined orbits are separated by 72°, i.e., the RAAN values for the 5 inclined orbits are 0°, 72°, 144°, 216°, and 288°. All the calculations, analysis, demonstrations, figures, and the video presented in Telesat’s Petition are based on the 72° separation for the RAAN values for the inclined orbits. However, there were two typos in the RAAN values in Schedule S. Specifically, in the Schedule S the RAAN values for the five inclined orbits were as shown in Table 1: Table 1: The RAAN values from the submitted Schedule S which included typos Orbital Plane RAAN [degrees] Number in the Schedule S 6 0 7 36 8 72 9 108 10 144

The correct value of RAAN for Orbit 7 is 216° and the correct value of RAAN for Orbit 9 is 288°. Table 2 shows the correct RAAN values for the five Inclined Orbits. Table 2: The correct RAAN values for the 5 Inclined Orbits Orbital Plane RAAN [degrees] Number in the Schedule S 6 0 7 216 8 72 9 288 10 144 The typos appeared only in the Schedule S and did not affect any part of the calculations, analysis, pictures, video, and demonstrations presented in Telesat’s Petition. We regret these errors. Please let me know if you require a corrected Schedule S. Should the Commission need additional information, I can be reached at eneasmith@telesat.com or 1-613-748-8700 x3279. Very truly yours, /s/ Elisabeth Neasmith Director, Spectrum Management and Development 2
