Retrograde Orbit Ground Track. Technically, a retrograde orbit is an orbit with an inclination of more than 90°. Orbits with repeating ground traces are useful when identical viewing conditions.
The inclination can be determined by observing the satellite’s ground track. All fourteen pursue retrograde orbits with orbital periods of about 2 earth years (588 to 768 earth days) and inclinations of 154 ± 11°.
Technically, A Retrograde Orbit Is An Orbit With An Inclination Of More Than 90°.
Here we have four possible solutions to design a repeating ground track orbit:
All Fourteen Pursue Retrograde Orbits With Orbital Periods Of About 2 Earth Years (588 To 768 Earth Days) And Inclinations Of 154 ± 11°.
Orbits which move westward are referred to as retrograde orbits and for retrograde orbits we measure the change in longitude on successive orbits as positive to.
This Is Also Called Apparent Retrograde, Where The Satellite Is Still Technically In A Prograde Orbit, It Just Appears To Be In Retrograde From The Ground.

If a satellite is to be inserted into a retrograde orbit (opposite to earth rotation direction) is it accelerated straight in the desired westwards direction until.
