No One Avoidance Angle Will Prevent Interference, Telesat Canada Says

No single avoidance angle will sufficiently define in-line events and prevent interference, Telesat Canada executives told all three FCC commissioners, according to a docket 16-408 ex parte filing posted Tuesday. The avoidance angle between two systems depends on elevation angles, Telesat Canada said, saying a "share in-line events" regime for spectrum essentially would work as band segmentation due to the number and frequency of such events. The company plans a constellation of 117 interconnected low earth orbit satellites, with two prototypes to launch this year, and said it met with the FCC to discuss its petition for access to the U.S. market for its non-geostationary constellation (see 1611160010). The filing said Telesat Canada representatives -- CEO Dan Goldberg, Senior Vice President-Corporate and Business Development Michael Schwartz and Chief Technical Officer Dave Wendling -- also met with International Bureau staffers, including acting Chief Tom Sullivan.
