Insurance market could face $192m+ Eutelsat 5 West B satellite loss
28th October 2019 - Author: Steve Evans

Satellite industry observers are discussing the potential for the EUTELSAT 5 West B geostationary satellite to become a total loss, which could cost the insurance market at least $192 million.

Named EUTELSAT 5 West B, the vehicle faced a potential malfunction related to a solar array which industry insiders suggest may not have extended fully, or even at all, when the satellite reached initial orbit.

Eutelsat 7A may now move to 5 west after 7C moves to 7 east if efforts to rectify the problems with E5WestB are not successful.

Eutelsat said in a statement Thursday that it is investing an apparent solar array anomaly on spacecraft.

“An incident occurred on one of the two solar arrays on the Eutelsat 5 West B satellite, as it approached its orbital test location,” said Marie-Sophie Ecuer, a Eutelsat spokesperson. “An inquiry with Northrop Grumman to investigate the causes of the incident and assess the impact on the performance of the satellite is underway.”

Looks like E5WB has hit something a similar incident happened to Eutelsat W5 suffered in 2008 the loss of one of its solar arrays due to the array's failed drive motor, leading to a switch-off of 4 of the 24 transponders.

We may end up with 3 satellites @ 5 west E5 West A + E5 West B + another satellite.

So all is not lost on the Eutelsat 5 West B satellite as it has a Ku payload of 35 equivalent 36 MHz transponders,

Maybe another satellite can provide support @ 5 west there are a lot of spare empty satellites about :-

Default Failure of Eutelsat 5 West B to start due to damaged solar panel

Contenders for moving to 5 west in if a new satellite Eutelsat 5 West C will need to be constructed it will take 3 to 4 years,

Eutelsat 7A @ 7° East 57 Ku band Tp's Approx 26 Tp in use
7A Q2 2021 is the end of geostationary service short term,

Hotbird 13E @ 13° East with 38 Ku band Tp's only 3 in use
End of life Q4 2024 would seem to be the ideal contender as it is not needed @ 13 east now,

Hotbird 13B & 13C each have 64 transponders x 2 =128 transponders available with only 95 in use @ 13° East & 33 spare,

Eutelsat's silence is of some concern as they do not seem to be able to make a decision maybe 5 West B can be repaired but the lack of test carriers make this unlikely so looks like it is of no use @ 5 west as originally intended.
