"DirecTV 10 is currently operating at the 102.815° orbital location. As DirecTV has previously informed the Commission, that satellite suffered a post launch anomaly that has limited the capacity available in certain local markets. DirecTV believes that it can ameliorate this condition, but will need to discontinue commercial service from the satellite and relocate it slightly so that it is not within the cluster of it's other operational satellites. Accordingly, DirecTV intends to move DirecTV 10 to the 102.6° position to conduct the restorative procedure. During this migration, DirecTV 10 will continue to provide service to subscribers. However, over the course of this migration, DirecTV intends to transfer all traffic from DirecTV 10 to DirecTV 12, DirecTV's newest satellite which has just completed in-orbit testing and is expected to arive at the nominal 103° location on or about May 11, 2010. At the conclusion of the STA period, the satellite will be in a position for the corrective procedure to be attempted."
This is big, DirecTV 10 has had spotbeam (provides HD Locals) issues going back to launch. They plan to move all DirecTV 10 channels to DirecTV 12, then move DirecTV 10 slightly, attempt a repair, and move it back.
This may add some time to the expansion of HD channels (though DirecTV 12 has two more ConUS transponders, thus 10 channels could be added while repair is attempted, and they can always cut into PPV), but could result in signifiacant improvements in their ability to provide HD Locals for more markets!
The STA allows this to start May 14 and take up to 30 days. DirecTV 10 will move to 102.6 degrees WL.
