Fleet and Operations Update

Intelsat’s average fill rate on our approximately 1,850 station-kept wide-beam transponders was 79 percent at June 30, 2018.
As of June 30, 2018, the HTS Intelsat EpicNG unit count was approximately 1,150 units in service, stable in comparison to the Intelsat EpicNG transponder count at March 31, 2018.
Our two launches for 2018, Intelsat 38 and Horizons 3e, are planned for launch on a single Arianespace rocket in September 2018.
Intelsat currently has seven satellites covered by our 2018 to 2020 capital expenditure plan, three of which are in the design and manufacturing phase or recently launched. The remaining four satellites are replacement satellites, for which manufacturing contracts have not yet been signed. In addition, we are working on one custom payload being built on a third-party satellite and a separate joint venture satellite which do not require capital expenditures, each noted below as a “Non-Capex Satellite.”
Our fleet plan includes the use of mission extension vehicles, or “MEVs,” to extend the operational life of two of our wide-beam satellites, which reduces overall capital expenditures in the near- to mid-term, but will increase operating expenses as each MEV enters service.
Our owned satellites, third-party payloads and a joint venture project currently in the design and manufacturing stages are noted below. Intelsat EpicNG-class satellites are noted with a small “e” following the satellite number.

Interesting thet they are looking to use Mission Extension Vehicles to prolongue the life of some of the older birds. Do we know which ones might be involved?

First Mission Extension Vehicle is for Intelsat-901 and take over orbital station-keeping duties, extending the satellite’s service life by several more years.

29.5°W Intelsat 901
Why Intelsat’s going with life extension over refueling - SpaceNews.com

Intelsat 901 with MEV-1 will probably move to 24.5 west as Intelsat 905 must be very low on fuel now launched on 5th June 2002
MEV-2 will probably go to 27.5 west or 1 west as both only have a limited time in geostationary orbit.

If they want a real challenge then the out of use Intelsat-26 at 65.8E could be a candidate. (inclined 8.1 degrees)

It begs the question of whether, in the long run, new satellites will be needed at all. If they can be refuelled then they can potentially last a long time. It's very rare for a satellite to fail on its own accord.

Also, would it be possible to bring back some of debris floating in graveyard orbit, refuel it and bring it into service?

Ive been wondering about this but most satellites are now "safed" at end of life - the propellant is drained & the onboard batteries are shorted out to prevent accidental on orbit explosions. No doubt there are a few that failed to safe correctly but sadly most of the derelicts will remain off air. I do wonder if some of the early ones junked before this became mandatory could be reactivated as demonstrations of the technology but the legal issues about interfering with satellites form other countries would be immense.

These MEV tugs could be used to pull derelicts down off orbit for a safe burn up though - science bird Envisat which suddenly went silent 4 or 5 years ago must be a candidate for a towed re-entry

MEV-1 (Mission Extension Vehicle-1 when launched with Eutelsat 5 West B end of May 2019 will go to Intelsat 901 (incl. 0.7°)29.5°W FlySat Intelsat 901 @ 29.5° West
MEV 1, 2
Current info in the link is out of date so I have updated to what is now known about the delayed launch of Eutelsat 5 West B & MEV-1,

The launch of the first MEV is slated for 2019 as a co-passenger on a Proton-M Briz-M (Ph.4) rocket with in-orbit testing and demonstration to be performed with the Intelsat-901 satellite in inclined orbit. This testing is scheduled for completion by late 2019. MEV-1 will then relocate the satellite scheduled for the mission extension service, which is planned for a five-year period after which Intelsat 901 will be place back into inclined orbit.

Intelsat will also have the option to service multiple satellites using the same MEV.

FlySat Satellite Launches 2019

MEV 2 will share the upper berth of an Ariane-5ECA rocket with Galaxy 30, while a third yet unnamed payload flies in the lower berth.

MEV-2 is expected to be in service by mid-2020 on a five-year mission with an yet unrevealed Intelsat satellite.mev-1__1.jpg

If the original plans are followed, 901 will be moving to graveyard orbit soon. Then 901 & MEV1 will do testing & tech stuff safely away from the main geostationary area. MEV1 then moves 901 back into service.

Im really looking forward to fllowing the MEV concept & seeing how it works out - about time a space tug concept was tried :)

Intelsat SEC filing Form 20-F for last year (2018) is available since a few days:
SEC Filings | Intelsat
There is a link to a pdf.

As usual, there are the interesting End of Service Life estimates, on page 30 & 31.
Several have it increased up to 1 year.

Compared to the 2017 form 20-F, only one satellite has its life shortened:
Intelsat 9 (incl. 4.7°) at 66.15°E, from 2020 Q3 to 2019 Q3.

Satellites ending 2019 Q4:
Galaxy-11 (soon from 44.9°E to 93.1°W)
IS-12 (moving now from 45.1°E to 64.25°E)
IS-26 (62.2°E)
IS-902 (62.0°E)
IS-905 (24.5°W)

For the first time, I see several satellites have their life increased more than 4 years.
I think most are planned MEV candidates. They must have a lot of trust in the concept!
29.5°W IS-901 from 2018 Q2 to 2024 Q3 (moving to 27.5°W when connected to MEV)
31.5°W IS-903 from 2018 Q3 to 2030 Q4
45.1°E IS-904 from 2018 Q4 to 2025 Q1 (moving to 29.5°W soon)
68.5°E IS-20 from 2030 Q3 to 2036 Q4
76.2°W IS-16 from 2028 Q1 to 2035 Q4
53.0°W IS-23 from 2030 Q4 to 2040 Q2
34.5°W IS-35e from 2033 Q3 to 2037 Q2

(There will be a few more, I only checked the arc 120°E to 90°W)
