Regarding the P51's the star pair can play a role. I tried it with a few pairs and got almost perfect angles each time, even using each of the pairs you posted so I am thinking this is user error with marking somehow.Hi,
Sorry for my late reply but I was occupied in other things … I did again some testing, about my previous Q1 and Q2, and I tried to point out what I am doing and observing; inside the 2 zip files some sceneries and some pdf in which I described in details the problems I faced for your further analysis.
Thanks as usual.
FYI: during P22 on day 7 I noticed that I can maintain LVLH heads up attitude (by SRF MFD) with a -ve 0.075 deg/s pitch rate (manually created by IMPULSE mode) and the FDAI ORDEAL at 0-0-0 ... but this time there was a P52 "nominal" before, indeed also FDAI 1 (inertial) was showing 0-0-0 at time of start of the orb rate ... does this observation may help to shed light on my issues on day 6, when the REFSMMAT was different? (and the FDAI 2 GDC driven was aligned to the FDAI 1 INERTIAL driven with a different REFSMMAT) ... just guessing....maybe uncorrelated facts...anyway for P22 it works, no issues there
For the ORDEAL, that actually is the "correct" behavior for a retrograde attitude/REFSMMAT. Since the ORDEAL can only rotate one way, it rotates "away" from your position since you are using a retrograde DAP rate. You will notice your spacecraft stays in an orb rate attitude, but the ball rotates away from it and this behavior was seen on the actual mission as well.
