I'm currently working through some practice exercises and one is about how many minutes per orbit a spacecraft spends above a certain latitude. How can this be calculated? I can't find any equations and visualising the problem using GMAT hasn't helped me.
Here are the parameters:
- Semimajor axis a = 35,000km
- Eccentricity e = 0.7
- Argument of Perigee = 320 degrees
The spacecraft is in a polar prograde orbit (assuming polar means dead on 90 degrees here) and the question is how many minutes per orbit are spent above the 70 degree latitude boundary.
I don't even really know where to start, and can't find any help in the textbook or other materials!
