I'm comparing how the Argument of perigee (
AOP) changes for 2 orbits (
O2). The orbits are equal, but the difference in inclination is 0.05deg. I have to choose the orbit, which change in
AOP is less.
I made simulation in
GMAT in 1 year and 5 years time interval. The problem is, in the first scenario
AOP(O1)>AOP(O2), however, in the second
AOP(O2)>AOP(O1). Also, different parts of time interval (1st year, 2nd year, etc.) affect the AOP differently.
- On which time interval simulation should I rely?
- Which orbit should I choose in terms of stability of AOP (on the basis of plots below)?
This is a plot of AOP change in 5 years:
- Central body- Earth
- JGM-3 21 degree to 21 order
- Sun and Moon
- Atmosphere model- JacciaRoberts
