l*lIndustry Canada lndustrie Canada Our file: 46215 (141291 RH) QCT I O 2007 Mr. Steven Nichols Executive Vice-president, Operations TerreStar Networks (Canada) Inc. The Exchange Tower, Suite 1800 130 Kings Street West Toronto, Ontario M5X lE3 Dear Mr Nichols: I refer to your letter of September 24,2007, in which TerreStar Networks (Canada) Inc (TmeStar Canada) seeks confirmation that its plan to operate its mobile satellite at the 11 1.O"W orbital position is in keeping with its April 27,2007 approval in principle. TerreStar Canada's approval provides for operating the satellite at the 1 11.1"W nominal position. Condition 3 of the approval states that Terrestar Canada must operate its satellite network in conformity with the ITU Radio Regulations. Further, Article 22 of the Radio Regulations requires the satellite to maintain its position within a certain tolerance (+/- 0.1 degrees) of the nominal position, but provides that the operation of the satellite need not comply with this requirement as long as the satellite does not cause unacceptable interference with another satellite that does comply with the tolerance. It is the Department's view, therefore, that TerreStar Canada's satellite operations at the 1 1 1 .O"W position (+I- 0.05 degrees) would be consistent with the April 27,2007 approval in principle. If you have any questions about this letter, please contact Richard Hiebert at 613-998-4333. Yours sincerely, Chantal Beaumier Director, Space and International Regulatory Activities
