What is Sun Synchronous Orbit ? • An earth satellite orbit in which the orbital plane is near polar and the altitude is such that satellite passes over all places on earth having same latitude twice in each. Synchronous orbit was a spatial relation in which an object orbits a massive body (usually a planet) in the same period that the body rotates, and does so in the same direction, often at an equatoral incline. To an observer an object so orbiting would generally appear to oscillate north and south.

What is Sun Synchronous Orbit ? • An earth satellite orbit in which the orbital plane is near polar and the altitude is such that satellite passes over all places on earth having same latitude twice in each. The sun-synchronous orbit results from perturbation effects that are not simulated. That said, the orbit solver in KSP is one of the cheapest things in the simulation.

A sun-synchronous orbit is always over the solar terminator, as it precesses around the Earth at roughly 1 degree per day (think about it: 360 degrees in a circle, ~365 days in a sidereal year). So the Sun will appear low over the horizon, but will never dip below it.

Web. Web. An orbit with an inclination between 0 and 90 degrees is considered prograde or direct (many astronomers prefer the latter term when it comes to natural satellites) and travels with the direction of the Earth's rotation. An orbit with an inclination between 90 and 180 is retrograde and travels against the Earth's rotation. What's a geosynchronous orbit ? It's a near-circular orbit, with an equatorial inclination near 0°, and with T = sidereal day ( 86164 seconds). Geos means "Earth", in ancient Greek. So, a "marsynchronous" orbit would use the same principles. For that, we need to know the duration of a sideral day on Mars. Thanks Wikipedia :.
