Galaxy 17 to Replace SBS 6?

[photoman76]

Galaxy 17 was scheduled to be launched today, but the mission was delayed do to high winds. They will try again tomorrow. http://www.arianespace.com/site/news/news_sub_missionupdate_index.html

Galaxy 17 is supposed to replace Galaxy 11 at 91 degrees West. But Panamsat has requested temporary authority to operate it at 74 degrees West for a period of 180 days.

So it looks like SBS 6 may be replaced by July 1st.

Galaxy 17 is a C band only bird. SBS 6 will be replaced with Horizons 2 sometime within the next 6-8 months.

SBS 6 is the last of what remains of the original SBS fleet (SBS1 - SBS 5). I think Intelsat knows the time is near for SBS6 retirement since they have a filing to request permission to operate Galaxy 17 at 74.05 deg W until the end of the year, by which time Horizons-2 should be operating if all goes well. Worse case scenario, Galaxy 17 replaces Galaxy 11 since Galaxy 17 is already granted operation at 91 degrees West and maybe Galaxy 11 will go to 74.05 deg W as it continues to experience solar array fog up and power generation degradation.

Galaxy 17 has 24 Cband and 24 Ku transponders:

It's possible that Galaxy 17 will only be an in-orbit spare at 74 degrees West and they will still use SBS 6 until Horizons 2 is launched. Galaxy 9 (Cband only) is also located at 74 degrees West.

I stand corrected. Gal 17 is C/Ku. I was thinking of Galaxy 9.

so is it at 91 degrees?

Not yet. It appears that after testing it will go to 74 degrees West for up to 180 days. Eventually it should go to 91 degrees West and replace Galaxy 11.
