So your saying ,That launching a satellite and getting it to its testing spot, Testing it ,and moving it over into its home location can be done in 30 days. No way! How long did it take for the Directv 11 and Directv 10 to get into the proper orbit and testing spot? not a few days that I can tell you for sure.

Other than it being pretty crowded at 110W, it shouldn't take very long at all. E11 should provide a good benchmark for how long it really takes to get a Sea Launch satellite in place.Your Dreaming! But we'll see.
The only unusual cargo on E11 will be the video camera and that shouldn't require days of testing and aiming like spotbeams would.
True, But I can't see a Satellite thats not even launched yet, being operational in 30 days. 60 days maybe, 90 for sure.
You are comparing apples and oranges. DirecTV also played around with D-11 a good bit for a BSS experiment.
Listen to rocatman...he knows his schhhhtufff on this
I'm talking about from the time of launch until its in its 110* Geo. orbit, How long?You are comparing apples and oranges. DirecTV also played around with D-11 a good bit for a BSS experiment.

DIRECTV 11 has been aloft for 117 days and counting. At least one third of that time has been spent testing unrelated technologies.
DIRECTV 10 launched from Baikonur, so it isn't a good benchmark.
Right,But of that time do we know the exact days it took to get into its testing spot after launch? 15? 25? days? anyone?
Well it took over 2 months for D11 to get to its geo orbit. If I'm reading this thread correctly. Why would an E* satellite be any faster?http://www.satelliteguys.us/directv-forum/128908-directv-11-satellite-tracking-testing-8.html
Check post #2 at D11 Sat: Post Separation Discussion - DBSTalk.Com to see exactly where D11 was and when. It shows that it got to the 99.4 test location 70.7 days after launch. Now what's unknown is did Boeing/DirecTV take their time getting it there to save fuel since they also needed to move it to 101 for the BSS testing and then move it back to 99?
And the memorial for it will start at 7:00 AM.
Just kidding. (Dear God, please let this one go up without a hitch.
)This could be true, But I remember the D10 taking at least 30 days as well to get into geo orbit. Early July launch, 8th or 9th if I recall, and wasn't operational untill September 26, With a target of September 1st. But problems delayed that. I just can't see 30 days ,Sorry! 60 I could see.
DIRECTV 11 took a very leisurely 70 days to get to its testing slot.
Echostar X, also a Sea Launch mission, was up and transmitting in 60 days. As E10 is loaded with spots, it required extra time and testing.
The biggest thing that E-11 does is free up both E-6 and E-8 for use elsewhere by Dish. The other two features on E-11 that should be noted is the camera on it and the massive power capability of it. For comparison, the Ciel-2 satellite with 145 spotbeam TP capability only has a payload power of 10.8 kW while E-11 has a payload power of 20 kW. E-11 at 110 W will only use 19 TPs since E-10 uses the Dish's other 10 TPs there for spotbeams. I believe for the SD TPs at 110 W, Dish uses a Forward Error Correction (FEC) of 5/6 with E-8 but perhaps Dish could go as low as 7/8 with E-11 allowing more useable bandwidth and therefore more SD channels per TP. I believe the old Voom service used 7/8 off of Rainbow-1 (E-12) at 61.5 W.
I believe Ciel 2 has plenty of power available for all 32 transponders based on the allowable EIRP's. I suspect that E11 has plenty of extra power on board to cover their historical problem with solar panal failures degrading capacity over the life of the satellite.
I did some research based on posts in this and other forums and it appears that the E-10 satellite that was also launched by Sea Launch to the 138.5 W slot for testing took about 11 days to get there. If E-11 is launched on schedule then based on what was done for E-10, it should be at 138.5 W around July 26/27. Testing of a CONUS only satellite like E-11 at most should take 4 weeks if that so a September 1 operational date is reasonable. August 15 is probably pushing it but I think Dish is anxious to get this satellite on-line.
