Extracting Data In-Flight for Display

[Kerlix]

Hello, all!

First, I'm very new to this and am sure this will become very clear to people.

I had an idea for something that would essentially pull trajectory data from a rocket/spacecraft in flight and display it in much the way the screens in a real world mission control would. 

Basically a graph showing altitude and range with other information displayed around it showing velocity, inclination, etc.

Ideally, it would be displayed on a 2nd monitor as I'd fear that having it open on the main screen would grind frame rates to a stone-age halt.

Then, once in orbit, have the ability to show that orbit and also be able to see the orbit change and the trajectory leading out to the Min or Duna, etc. And be able to switch the planetary body once a vessel is there.

A lot like the tracking station screen but visible while in flight while looking at the rocket/spacecraft and really just a 2D representation instead of a 3D "God's View" of everything.

I'm also interested in figuring out how to take data from, say Kerbal Engineer Redux, and being able to export that data to a spreadsheet. In that way, I'd be able to plot things like altitude, velocity, TWR, delta-v burn and the like. Being able to do that in real-time or at least at constant intervals to create plots and stuff.

Is something like this possible? If so, where would I begin to learn how to extract the relevant information and have it displayed inside of my module?

Thank you for any help you may be able to provide.

Unfortunately the best documentation for KSP is the source code for mods. There is an official documentation site but it's a dump of the API with few comments. I would suggest you start by looking at the code for mods that do something similar like

Good luck! (and happy modding)
