| Oct 23, 2013 at 19:58 | comment | added | PearsonArtPhoto♦ | Well, it would uniquely identify a point, but I really want to do a plot of performance of a subsystem vs the ground track. Lat/Long/Heading is too many data points... | |
| Oct 23, 2013 at 19:56 | comment | added | Hobbes | Would the heading of the spacecraft serve this purpose? Then you'd have a lat/lon/heading trio for your position that uniquely identifies the ground track, and it might be observable from the ground. | |
| Oct 23, 2013 at 19:51 | comment | added | PearsonArtPhoto♦ | I don't really want it to be tied to time of day. The Longitude of the Ascending node would be of some interest, however. | |
| Oct 23, 2013 at 19:49 | comment | added | user29 | Hmmm... still trying to wrap my head around this. So, assuming you're not as worried about the shape of the ground track as you are it's current "position", are you looking for something like the local time at the ascending node? Or even just the longitude of the ascending node itself? | |
| Oct 23, 2013 at 19:45 | comment | added | PearsonArtPhoto♦ | @Chris: Basically I want a metric to measure the ground track it is making. The metric shouldn't be much different if I changed the time 10 minutes in either direction, with the corresponding distance change. | |
| Oct 23, 2013 at 19:44 | comment | added | user29 | The main difference I see is that one is an ascending pass while the other is descending - is that what you want to differentiate? | |
| Oct 23, 2013 at 19:42 | comment | added | PearsonArtPhoto♦ | @Chris: Basically, I want a number that can tell the two ground tracks apart, despite having a nearly identical lat/long | |
