Can anyone help me to understand what data is displayed here:

14.14.02-05012010-3122-iss-expedition-23-progress-37-docking-live.jpg


I understand part of it: Dv and º of course, probably related to the docking port.


My goal is to try to replicate this display using LUA. I finally understood how it works and I'm looking for a simple first project based around data display.

Any help regarding those values and how to get them from Orbiter is welcome. :thumbup:
 
For example in the lower left (p and \dot{p} in cyrillic) you have distance and approach velocity (r and \dot{r}), as measured by radar.

The same data on the right side seems to show docking port data.

Somewhere at home, I have a better drawing of the display.
 
On the right side under "Kypc" (Kurs, or course) is the attitude display.
Above that I'm not sure, because part of the light text is obscured, but it appears to be angles of some sort.
 
Some of those figures on the right would be relative motion in the various axes (x, y, z)
 
Interesting puzzle :) !

Yes, those are angles, but relative to what ?

Here's my progress in understanding the overall display:

The top right coordinates are "Line Of Sight" coordinates.
The bottom right are of course "Kurs" coordinates.
"Braking" is one of the status (I think)

From seeing several docking videos online, my current best guess is:

Code:
"line of sight coordinates" 
(variable, scale, number format)
ωX	º/S	0,000
ωY	º/S	0,000
ωZ	º/S	0,000

"Kurs"
(axis, variable, scale, number format)
	 γ	º	0,00
x axis	 ηΠ	º	0,00
	 ϑΠ	º	0,00

z axis   ρ	º	0,000
	 ρ'	º	0,00

y axis  Ωy	º	0,000
	 Ωz	º	0,000

Tracked down a manual regarding the ISS computer systems.

http://www.spaceref.com/iss/ops/sm.comp.system.man.controls.pdf

On page 36 you can see the "Rendevous Format" computer display: "This format displays information on ISS angular velocity, range, relative rate of approach, current
attitude control mode, and Kurs system operation status."

Just to let you know that I was able to get the pitch/yaw/bank values of two spacecraft and show their difference on screen! :rofl:

On this case, both spacecraft are indeed aligned!

Of course, it's a flawed logic, since I'm not taking into account the docking ports orientation, but it's a major step for me in learning two things: LUA scripting and Orbiter's API. From what I've seen I can get some data about the docking ports, but I'll really have to study it...
