I'm not seeing much in there about Ku band. I would have expected an STA.
If they did (NOT) apply for a ku license for usa reception, they would likely not include the beam in the usa license aplication.

Thanks all. That makes sense to me. So if you're right in the middle of the highest strength coverage area, would it be possible to receive a continuous signal at 1 degree inclination, or would you still see drop outs throughout the day?

Id imagine channels would be migrated to G1 before this point, but out of curiosity, how much would the coverage area shrink at 0.5 or 1 degree?

If you're in the center of the beam, the inclination could theoretically go to half the beamwidth before loss became an issue. The reality is that many here are on the edge of the beam.

AMC-11 (the C Band replacement) is at 115W and moving close to 1 degree per day. Should be co-located with Anik F2 by the end of next week.

Anik F2 is definitely operating in an inclined orbit.

From the graphs you provided, it looks like the current cuboid is +/- 0.25 degrees in latitude. Am I reading this wrong?
East/West does not increase much so it becomes more of north/south ellipsoid.

Been reading up on inclined and the North/ South deviation can get quite large as in multiple degrees, if the operator chooses to not control it..

The article says uncontrolled latitude increases 0.8 degree per year.

Watching the data for a few days and it looks like ~0.003 degree increase in latitude offset per day. This is consistent with the earlier article post link which estimated 0.8 degree per year

0.023 degrees today.

The movement doesn't sound sustainable for fixed antennas.

Shaw used to have a page where you could download spreadsheets of channels with satellite and transponder information. Does anyone know where that information has gone?
