OhioBob Posted October 26, 2018 Share Posted October 26, 2018 23 minutes ago, Arrowstar said: So alright, question: are orbits around local bodies, like Kerbin, computed w.r.t. the body's new rotation axis and equatorial plane? For example, if I tilt Kerbin and then launch due east from the equator, I will be in an equatorial orbit. Is the inclination of that orbit with your mod 0 degrees (because it's measured against Kerbin's new equator) or something else (because it's measured against the universal coordinate system)? Currently orbital elements are in reference to the ecliptic (universal coordinate system). A due east launch from KSC will put you in orbit around Kerbin's equator, but the KER readout will say the inclination is ~23.4 degrees (Kerbin's axial tilt per this mod's cfg). Having a readout that gives orbital data in reference to the equator is something that I think is needed. I suspect it will likely require an upgrade to KER (and MechJeb, and whatever else uses or provides such information). Quote Link to comment Share on other sites More sharing options...
vardicd Posted October 26, 2018 Share Posted October 26, 2018 (edited) Quick question, Is there anything this mod needs as a dependency? I see none listed, but when I download and merge the files into the game directory, it doesn't seem to work. I haven't played around with it too much yet, I've had very limited time to troubleshoot, so it may just be that I've done something stupid that will be simple to correct, but thus far I'm not seeing any errors in the install file structure.... It was, in fact, something stupid. The mod was working just fine. I just had to take a better look at it.

Pand5461 Posted October 26, 2018 Share Posted October 26, 2018 9 hours ago, OhioBob said: The line of nodes of the equator randomly changes from one game launch to the next. For instance, put a satellite in an equatorial orbit (you'll have to figure out the LAN by trial and error). Shut the game down and restart. The planet's axis will now be pointed in a different direction and the satellite will no longer be orbiting around the equator. I did it three times. First time the LAN was 84.54 degrees, second time it was 198.33, and the third time it was 266.13. That answers my previous question I was suspicious that tilt angle only is not enough to describe a rotation properly, and an additional azimuthal and a reference vector are required.

Dagger Posted October 26, 2018 Author Share Posted October 26, 2018 (edited) So regarding the navball I've been doing some tests with the (still unreleased) 1.1 version (you can compile it tough) and it looks right as the "north" is pointing to the true north of the planet This is how a plane going north just after takeoff looks in default KSP without the mod and with the mod: Ignoring the camera rotation, both planes are going to the "north" and you can check it in the commnet line that the heading is correct. Same applies when going east (ignore the camera rotation): I'm aware of the planet rotation bug, from what I see I should somehow apply a rotation based on the epoch or some other orbital parameter so it's consistent across saves... I'm working on that PS: Another test I did. In this case Kerbin has a tilt of 45º and the plane is going east, I extended the ecliptic line and the angle is correct Edited October 26, 2018 by Dagger Quote Link to comment Share on other sites More sharing options...
Superfluous J Posted October 26, 2018 Share Posted October 26, 2018 Thank you. I knew this was possible but lacked the skills to do it, patience to learn, and jerkiness to demand it of others.

FreeThinker Posted October 26, 2018 Share Posted October 26, 2018 (edited) @Dagger may I suggest that PlanetTilt.cfg uses planet names instead of index numbers, that would make it significantly easier to modify and robust for any changes in star system composition.

I placed a satellite into a equatorial orbit and pointed it at +Normal. The Level and +Normal indicators on the NavBall remained positioned exactly on the intersection of the horizon and the N line throughout an entire orbit. This tells me that the satellite's longitudinal axis is continuously pointing at true north. This is what we should see if the NavBall were correctly identifying the new north pole. When I put the satellite in non-inclined orbit (relative to the ecliptic), the Level and +Normal indicators would oscillate around north, pointing true north only two times per orbit. This is again what I would expect if the NavBall were working correctly. Edited October 26, 2018 by OhioBob Quote Link to comment Share on other sites More sharing options...

Catatau_27 Posted October 26, 2018 Share Posted October 26, 2018 Dear Mr. @Dagger I have something to report, NavBall, using the mod is misaligned a few degrees, I know the planet needs an angulation and that favors in several situations however with Naval misaligned it is strange to pilot in Kerbin and confuses me enough when I am flying by instruments. However your mod mod is incredible, what is missing now would be the tidal effect. =) Thank you for making planetary tilt possible. Quote Link to comment Share on other sites More sharing options...
