I am trying to calculate the orbit parameters for a cubesat (Duration, eclipse time and sun time) can someone help please

    $\begingroup$ We need a bit more data before we can calculate anything. What altitude and inclination are you planning to use, for instance? $\endgroup$ – Hobbes Nov 17 '15 at 18:03

    $\begingroup$ What information do you have? Are you planning an orbit for a project, or are you getting some information about an existing cubesat? Without a better question, we can't give a useful answer. $\endgroup$ – Ross Millikan Nov 18 '15 at 4:54

The easiest way to get this information is to use a tool such as the Satellite Tool Kit (STK). Essentially, this information varies over time, especially for high inclination orbits. A good orbital simulator will allow you to enter mean altitude, inclination, and eccentricity (Or alternatively apogee/ perigee/inclination)

If you already have the satellite in orbit, then you can import the satellite into STK, by looking up the satellite from their orbit. The eclipse times are an available report.
