I use the STS-117 orbital elements from JSC and STS Orbit Plus will calculate and show the TDRS times and sunrise & sunset times for STS-117 for each orbit, for instance right now it tells me that we have entered in TDRS-West coverage (usually great TV KU coverage on this TDRS) and we will be on this TDRS Ku pass for 50 minutes so we should get some great TV when the linkup from the station/shuttle is more in sight with TDRS-West. This will be a daylight pass too and we will be in daylight until 8 PM EDT time (when a post-MMT briefing is to be aired).

During this ratty comm period could you post a few screenshots from your STS-Plus setup?
Another Jettison!
Edit: Could I also have a link to where you get the JSC 117 Elements? Are they in TXT forum for easy loading? -

Just over 3 hours into the spacewalk.
Ratty Comm and no Ku still

Zachstar, I posted a screen shot of STS Orbit Plus, as known as STS Plus, as you asked, it is a DOS based program which you can run inside Windows 98 or Windows XP. I am running this program inside another program called DOSBOX becuase I am using the VISTA operating system and I cannot run DOS programs like this in full screen mode in VISTA like you can do in XP or Windows 98. The sunrise, sunset, TDRS times are listed in the lower righthand corner, that is what I am referring to when posting these times. It fills in the gaps that the NASA PAO makes sometimes.

Anyone else noticing that you seem to get better Ku video from north of the equator?
Pointless near the Zoe,
and Stills near Australia? -

Thanks for that screenshot and explanation sts1!
Spacewalkers moving on to next jobs. (I diddnt hear what they were)
Anyone who is watching feel free to add detail on the jobs and report as much as you want! -

With the extra EVA now alotted for OMS pod repair, things are going to get really dicey if the other solar array on the P6 truss has trouble folding up like the previous one did.... Let alone if their trouble opening up the new array.

It depends on the angle between the shuttle KU antenna and the TDRS satellite that is fixed in a certain point in the sky when viewed from the shuttle, the shuttle is constantly orbiting the earth 16 times a day. The TDRS satellites are about 35000 miles higher than the shuttle orbit and they orbit the earth once a day and since the TDRS orbit at the same speed as the earth's rotation, the TDRS satellites appear to be standing still relative to the shuttle and ground. When the ISS/shuttle pass near or directly under the TDRS, coverage is great, and as it moves away, the coverage starts to get blocked.

I don't know, This crew seems to have a habit of getting stuff done on time and usually early. I'm sure if the retract acts up they will beat it into submission within an hour or so. They know how to handle this junk now.
And the OMS pod blanket tuck and pin wont take long at all! Im sure they wanted that extra EVA to get more of these get aheads done. -

All this talk about STSPLUS (and the sad passing of David Ransom) and I'm going to have to go dust off my 8-year old laptop and run some TLEs through STSPLUS in DOS 6.22...

Of course! We just outta have a way to predict that based on orbit attitude and gimbal range of the 2 Ku systems.
Then we could really make a prediction on passes!
