I thought so too, but at least visually the FRCS jets are being fired.Sounds like only the aft RCS is firing.

The RCS thruster directions are +/- correct (considering it is still 1 or 2 thrusters per axis), so a translation will also generate a rotation, and rotations will have some coupling. I don't how much of this was "actively" countered by the FCS (as opposed to "passively", as attitude deadbands are exceeded)... because I haven't got to it yet (still need the full RCS first).GLS: Is it normal for translate down to induce a very strong pitch up rate, even in VERN? That doesn't seem right to me. It makes the orbiter near uncontrollable for prox ops.
OK, I'll adjust my prox ops techniques then. Speaking of prox ops, the A2 XPNTR LOS RATES needles are very twitchy, even more so in the x1 mode. Is this related to the semi-implemented Ku band system implementation at the moment?The RCS thruster directions are +/- correct (considering it is still 1 or 2 thrusters per axis), so a translation will also generate a rotation, and rotations will have some coupling.

If you go "full bananas" on the translation, you can quickly saturate the attitude control, especially in vernier mode. I guess the idea would be to do less Apollo 13 movie style thrusting, and more "steady as she goes" with discrete pulsing for translation.
Yeah, they dance because of numerical instability: the angles they show are small, and so a small change means a lot. EA-2 is probably missing a filter to smooth the data, plus the needles wouldn't move that fast, so it would also smooth the motion. Just checked, and they don't use the "new" logic that is in the O2 panel needles... I'll eventually get to it.OK, I'll adjust my prox ops techniques then.

Hi there!Hi guys, I apologize if there was a similar issue that was resolved, but I couldn't find it. All my MFD's are black and they don't display realistic images that I see everywhere. Do you believe there is a conflict with some other Module like delta glider IV for example?
I just did a fresh install, there was some conflict with my other files, it's all good now, thanks for your time.Hi there!
If you are talking about the image I posted above and the views in the TV monitors, that is still under development, so the current version has nothing there.
If you actually mean the 11 MDU displays, then that would be a problem... could you open one of the included scenarios and then post the log please.
Hi there!Hi, does the SSV have EVA capabilities?
It seems that you already have a "LOAD" for Item 22, so no need to key ITEM 22 ENTR again. (I-Loaded values?)Not sure if this is the right place to ask this. But I'm trying to do an OMS burn for orbit insertion and I'm always getting an "Illegal Entry" error. Am I doing something wrong?
Like @indy91 said above, your TIG is in the past... which is actually allowed, but only 5 minutes in the past, and you are over 9.Not sure if this is the right place to ask this.

Thank you.The RMS has 2* basic frames of reference:
- "End Effector": the EE will move following a reference frame that is centered at, and follows the very tip of the RMS, so a forward command will move the EE forward, left will translate the EE left, etc. This mode is good for going after something and grappling it, because it will move as if you are sitting on the EE.
- "Payload Bay": this move will move the EE in respect to a reference frame aligned with the PLB, regardless of the orientation the EE is at, so a forward command will move the EE forward in the PLB, left will make the EE translate starboard, etc. This is very helpful to put and take payloads out of the PLB, because you can command a vertical motion of the RMS+Payload, even if the Grapple Fixture is at an angle, like in the PFTA. The "Payload Latch Test" scenario is a good place to play with the RMS and a payload with 2 GFs at different orientations (that's why I created the PFTA vessel).
The RMS mode is selected using the Mode rotary switch, top left on panel A8U. "ORB LD" and "ORB UNL" are currently the same, and use the PLB reference, and the "END EFF" uses the End Effector reference. There are also single and direct modes, in which you can command a single joint, which is often needed when the RMS is at a position that the augmented modes can't handle (e.g., unstowing). The other modes are not implemented yet.
*) currently that is it, but eventually custom reference frames will be possible
The official STS-31 pres kit from JSC doesn't have the details but the Media Resource Kit (MRK) from Rockwell Intl (Orbiter Vehicle prime contractor) does: https://historycollection.jsc.nasa....ory/shuttle_pk/mrk/FLIGHT_035-STS-031_MRK.pdf
- raise HST to low-hover position (I remember there were 2 "hover positions"... the press kit might have some info and/or diagrams)
