As of 6/16/2010, the corrective procedure ("amelioration") on D10 is complete.

As of 6/27/2010, D10 is now back at it's original location and transmitting all of the national HD that it had previously.

D10/D12 News (5/7/2010):
"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 arrive 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."​

Tomorrow's public notice:
On May 12, 2010, the Satellite Division granted, with conditions, the request of DIRECTV Enterprises, LLC for special temporary authority, for a period of 30 days, commencing on May 14, 2010, to conduct telemetry, tracking, and telecommand operations with the DIRECTV 10 space station during a drift of the space station from the 102.815º W.L. orbital location to the 102.6º W.L. orbital location. DIRECTV is authorized to provide commercial service to its subscribers during the drift of the DIRECTV 10 space station from the 102.815º W.L. orbital location to the 102.6º W.L. orbital location, and at the 102.6º W.L. orbital location, while DIRECTV transfers all customer traffic from the DIRECTV 10 space station to the DIRECTV 12 space station.

More good news. :D

In the last day or so I have started to see a lot of 771 messages. I looked up the first dozen (202,207,212,215,216,229,231,241,242,244,247,248 all HD) and according to Lyngsat they are all on DirecTV 10. Could this move be the cause of my problems? Is there anything I can do about it?

There has not been any confirmation of any movement of D10.

Post#1 always has D10's latest location, per the latest data available.

Perhaps someone try to steal your antenna. :)

As to mapping those channels - DTV often shuffle channels, so check latest assignments here, look into gct's tables and Sixto's dedicated thread.

I wonder if we'll have gaps in TLEs from NORAD during the drift, similar to what we've seen with the bigger drifts for D10, D11 and D12.
Again, the move is on the order of 100 miles, give or take. We're like to not see ANY during such a small move, or just one, and the next one show it more or less parked at 102.6º. That degree of movement shouldn't take very long at all.

When D10 and D12 are parked in their permanent spots, how far apart will they be? Also, why is the next new satellite being called D14 instead of D13?
If my math is correct D10 at its assigned location of 102.815° minus D12's assigned orbital slot at 102.765° = .05° separation which should translate into .05°/360° x the Clarke belt's orbital circumference of 164, 582 mi. = ~ 23 mi. at geostationary orbits

And D13 was originally scheduled to be a replacement satellite at 110°, but was canceled back in Nov. of 2007, thus "D14" is the official name for the next satellite in line following D12 to be destined for somewhere at the 99° slot.

YES! and for those who do not understand Latin, Fear of the number 13
Um, no. As pointed out in this very thread a few posts up, there was a D13 planned and the FCC had granted authority to construct, but Directv changed their direction with regard to the 110 slot, and the D13 application was withdrawn.

They were making a joke. No one actually believes that D13 is being skipped because some consider 13 and unlucky number.:)

I assume once D10 offloads channels to D12, there will be several days to a week before D10 starts the drift. If I were DIRECTV for a day, I’d make darn sure D12 was firing on all cylinders before moving D10. I wouldn’t be surprised if D10 waited two weeks before starting its drift.

D10 may have already started the Drift, no update since Friday.

Would DirecTV have to tilt or slightly change the orientation of the satellite to maintain service levels or is a 2 tenths a degree not enough for our dishes to notice?
