Eclipse Time Sun Synchronous Orbit Altitude. For orbital altitudes between 500 and 1500 km, the orbital period varies from about 95 to 115. Has the longest eclipse time because of shadowing by the full diameter of earth.
It looks like a sun syncronous orbit means, in general, that the satellite passes above the same parallel, always, at the same solar local time. Consider these 2 situations for a geo satellite ( i.e.
This Is The Angle Between The Ascending Or Descending Node And The “Mean Sun”.
At 800 km, it will be travelling at a speed of approximately 7.5.

Eclipse intervals for satellites in circular orbit under the effects of earth’s oblateness and solar radiation pressure.
This Orbital Sun Angle Is Often Referred To As Orbital Beta Angle And Usually Represented By The Greek Letter Beta.
