I've uploaded a link to OH. It's going through review, so it might not show up for another 24 hours.
Well, I think the Ku band antenna will have to wait as we need MDMs to talk to the displays on panel A2.
http://spaceflight.nasa.gov/shuttle/reference/shutref/orbiter/comm/orbcomm/kurndz.htmlRange tracking is always automatic, although computer-designated ranges are applied to the Ku-band system until automatic tracking is achieved. In the automatic tracking mode, the Ku-band system provides actual antenna angle, angle rate, range, and range rate data through an MDM for rendezvous and proximity operations. Data routed to panel A2 represent hard-wired azimuth, elevation, range and range rate information, which is not processed by the GPCs.
You replaced 2.0 with 3.0 on OH, but I still use 2.0 for some things. Can it still be downloaded... from SF?
Are you really sure that A2 is connected to the Ku-Band antenna via MDM and GPCs?

Yeah, you're right. I'm sorry, yesterday was a long day...
So, we can have the antenna search a target, around an area we specify by manually moving the antenna, and when it locks, the data is displayed in the 7-disp and "chart" on panel A2. Correct?
Yes, GNC SPEC 33 REL NAV.Correct. But DaveS is possibly right about needing a tiny bit of the DPS for changing from communication to radar mode (or back).
Yes, GNC SPEC 33 REL NAV.
COMM is only for monitoring S-band/Ku-band component temps, no rendezvous or comm stuff there. ANTENNA is just KU BAND systems stuff. The actual switching is done from A1U, KU BAND MODE switch. It has three positions, RDR COOP, RDR PASSIVE and COMM.Not sure, if that SPEC is required. I mean COMM or ANTENNA there.
AFAIR, REL NAV is only needed for incorporating radar data from EA2 into navigation.
For radar mode, it seems correct. But before that can happen, we need the activation procedure to put the Ku system into the proper state. And that involves a bit of DPS for crew interface (SM SPEC 76 COMMS and SM ANTENNA).If I understand the SCOM correctly:
POWER >> ON
MODE >> RDR PASSIVE
KU BAND >> AUTO TRACK
SLEW switches to desired antenna position
KU BAND SEARCH
(antenna starts spiral)
(antenna finds target)
(antenna starts auto track and info is displayed)
this would have the antenna tracking a target, while displaying all that pretty info on panel A2, correct?

It's DISP 76, so it only does output. But if it needs SM ANTENNA, then this is not going to happen.
My "Vandenberg offer" still stands.
This is correct. The KU BAND SELF TEST (ITEM 7) and I/O RESET KU (ITEM 8) is only interfaces between the Ku system and the GPCs. The COMMS display is what matters during Ku activation (mainly KU PWR OUT).I feel slightly ignored.
SM ANTENNA is not critical. The only function that is executed there is the Ku Band self-test. Since we have no failures right now, its no big loss.
And again: Before 4.0 goes public, we should also have the time to add SM ANTENNA to the DPS anyway, so the release goals would be achieved.
We just can't execute a self-test before the DPS is done.
We do:... and the KU band antenna just hit another brick wall. Correct me if I'm wrong graphics department folks, but we don't have a panel A1U. :facepalm:
