Eclipse Time Sun Synchronous Orbit Altitude. With 𝛽 equal to 90. Its orbit allows hinode to observe the sun.
0, no eclipses exist at any altitude. Eclipse intervals for satellites in circular orbit under the effects of earth’s oblateness and solar radiation pressure.
As 𝛽 Increases The Satellite Is Sun Facing For A Larger Percentage Of Each Orbit, Thus Decreasing In Eclipse Duration.
The parameter that determines the actual illumination time histories is the orbit o’clock angle.
Two Main Categories Of Optical Earth Observation Satellites Are Geosynchronous (Those That Continuously Stare At The Same Area Of The Earth’s Surface).
For orbital altitudes between 500 and 1500 km, the orbital period varies from about 95 to 115.
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.

The Altitude Is 300 Km Although The Results Have Little Variations With Altitude (A Slight Increase In The Orbit Inclination And Slight Decrease Of The Eclipse Time).
At 800 km, it will be travelling at a speed of approximately 7.5.
