 06-21-2008, 06:43 PM #32 orwellkid Addon Developer First off, this is a mighty fine project kind sir. I would be damn happy to use this. As for the Map MFD, as far as I can tell, it dispalys your path based on inclination. So, to display it, it would be something like: Split the map into 2 zones, Seperated by the AN/DN Zone 1, would dispaly course as: inclination - 180 = angle of decending node Zone 2, would display course as: inclination + 180 = angle of ascending node it would be a rather rudimentary line (projecting x1, y1 -> x2, y2, per zone), but it would be something. I'm not sure exactly how Martin does this with a wave formation, but it must be something similar, tying in the AN/DN lat/long juxtaposed Map lat/long. Just my 2 cents.
 06-22-2008, 02:14 AM #33 davewave Addon Developer Does anyone have some source code to the MAP MFD used in orbiter or even the MAP displayed in Aerobrake MFD. I've been trying to work out how to plot an orbit on a map and I've been using spherical coordinates whereby PHI is my inclination and Theta is given by the True Longitude. http://mathworld.wolfram.com/SphericalCoordinates.html This website explains all this but I'm only getting spherical representation. There must be an easier way. Just to reitterate, I'm duplicating the orbit projection which is seen on map MFD in orbiter but for my mission control mod.
 06-22-2008, 04:41 AM #34 spacegeek94 Orbinaut wowy! id love to use this, it sounds outrageously fun! good luck, cant wait to see the end product! maybe just maybe, see if martin might want to hook up with you to put this in newer versions of orbiter. maybe it will make it as a standard in future versions.
 06-22-2008, 06:05 AM #35 spcefrk Ph.D Student A quick suggestion: Could you make the interface sort of standard so that others could make "skins" for it? I absolutely love what you're working on here but I'd like to be able to use it in different styles -- perhaps a couple of different NASA styles (1970s, 1980s, Modern) or futuristic ones. It would be cool if we could select fonts and colors and whatnot. You definitely need the orbit displayed on the map (and I asked for this elsewhere) but could someone make a political map to show the track over? If I were running a mission control I'd be less interested in the color of the ground they're over than a map with radio ranges, political lines, etc... I'm not much good for programming anything but Matlab and Fortran, but if I can help, shout.
 06-22-2008, 06:34 AM #36 davewave Addon Developer Hi. The programming language isn't the issue, just getting the math is all I need. Skins are definatly on the horizon and not impossible for me to do but right now I'm getting the mechanics all working. What I could use is an internet test. Can someone run OrbConnect on an orbiter client and send me the ip address!

Well, what you're really trying to do is graph a sinewave on the map. You'd have an equation like y=PHI*sin(x-LAN), where PHI is inclination, LAN is longitude of the ascending node, x is longitude and y is latitude. You can use this equation to display the orbit.

Thanks so much. I'll give this a shot
 06-22-2008, 11:14 PM #39 Andy44 owner: Oil Creek Astronautix THe ground track only looks like a sin wave for a circular orbit in a low inclination, though. A polar orbit, for instance, looks like a square wave.
 06-22-2008, 11:15 PM #40 to be Orbinaut This probably seems obvious, but just in case, make sure your inclination is based on EQUATORIAL data.
 06-22-2008, 11:40 PM #41 davewave Addon Developer I don't know if this equation is entirely correct because if I was orbiting from north to south pole, this equation assumes a constant progression along the x-axis which clearly isn't the case in a high inclination orbit. I think there is more to it then just plotting a sin graph as well because if you look at a high inclination orbit you will see the peaks and troughs of the sine-wave are skewed to fit the bottom of the earth.
 06-23-2008, 12:55 AM #42 tblaxland Webmaster If the sim is running non-spherical gravity sources, you also need to take into account the regression of the LAN. There is some info in Orbiter\Doc\Technotes\gravity.pdf on how to calculate the rate of regression.
 06-23-2008, 06:21 AM #44 davewave Addon Developer Update: Ok I have just finished reprogramming the network code. Now its super stable. Upcoming features: * Attitude Display * Ascent Profile * Autoswitching maps based on current major body of influence The new code produces the highest possible frame rate of information and its all based on the orbiter clients frame rate.
 06-23-2008, 08:20 AM #45 davewave Addon Developer New Website Hi all, Well its official. Mission Control for Orbiter has a homepage. You can go there now by following this link. http://new-frontiers.sourceforge.net/index.htm The program also has a place on sourceforge so avid coders can help out if they like or just keep tabs. All further downloads and screenshots will be posted on this website so as to ease the burdern on Orbiter-Forum.com servers. Cheers!!
