Echostar 1 Drifting East

[nelson61]

Echostar 1 has departed 148W and is drifting east.

Drift Rate approximately 1.1 degree/day

84km below geostationary

Present location approximately 146.3W

Look out below!!

I wonder what their options are to move another sat (leased, presumably) to that location to keep the licenses.

Already done.

Do I need new bifocals or is that really 10,000 posts!!

nelson61, is there a stated arrival date that you can say?

Thanks,

Usually takes about a week to get the final altitude and drift rate. Sometimes, they adjust several times, other times the first movement is the only one they make. Yesterday. the numbers said it was about 1.1 degree/day.

It has been moved lower since that report and the Two Line Elements show it 113KM below Geo and moving 1.46 degrees/day. That works out to about 45 days. Add on another 7-10 days to bring it into final positon.

You can calculate and see all the technical details here.

Online Satellite Calculations - 20©07 Jens T. Satre

Clear the input panal and enter the satellite name in the first row. Any name or abbriviation will work. Then use N2YO or one of the other sites to copy and paste the current two line element directly below the satellite name. You will then have three rows of data. You can enter your long/lat and that will set everthing to your time zone and reference point. Click Load TLE and all the data is calculated.

Yep. Forgot about that.

And I sometimes wear reading glasses AND bifocal contacts!

nelson61, thanks for the info. I had noted the sat. was somewhat lower. Just for fun I will run a computation through Satre's formula. I was hoping that Dish had stated somewhere that "the satellite will be on location in x number of days" since otherwise we just have to keep tracking the satellite to see if Dish has sped up the movement or slowed it down. I'm sure Dish knows exactly when the satellite will reach its destination now that the movement has started.

Best regards,
Fitzie

They have received several routine 60 day extensions to complete the move and will need another one before it gets there.

Echostar 77W arrival scheduled for Aug 21

From today's Echostar FCC application for continued earth station communication with Echostar 1 during transfer.

"The satellite began its transfer from the 148​

? W.L. orbital location on June 29, 2009, and is expected to arrive at 77.15? W.L. on or around August 21, 2009."​

nelson61, many thanks. Now, barring collisions, etc.----we know what to expect!​

That extra capacity might fit in nicely with carriage agreements for more HD (such as ESPN-U HD) just after the start of the college football season...​

Best regards,

E1 has started manuvering, rising to 55 km below Geo orbit and slowing to 0.7 degrees/day.

 

[nelson61]

Echostar 1 was 14 km below geostationary orbit with the thursday morning Epoch and in the close vicinity of 77W. Looks like they were right on the mark when they said it would be on station Aug 21.

 

[nelson61]

Echostar 1 on station at 77.125W

Echostar 1 is in geostationary orbit at it's assigned longitude per latest Epoch ( 6 AM Central, 8/21)

 

[Scott Greczkowski]

Wonder how long before is in use?

 

[jmccurrytech]

Am I wrong, or isn't it for Mexico service?

 

[nelson61]

Echostar and partners control all 32 transponders at 77W and it is a guess as to how they will be used short term. I think Mexico service is using 6 to 8 tps on one polarity at the present time. If E1 is used for Mexico, it would leave the other 8 E1 single polarity transponders up in the air re; where will they be used, US or more Mexico service? E1 can support both Mexico and US beams.

 

[photoman76]

I'm seeing some new signals from 77° West. Transponders 27 and 31 are now on. No channels yet.

 

[TheKrell]

Neat.

So Echo4 is being put out to pasture. Echo8 will remain at 77?
