Sun-synchronous orbit gif
WebIn such an orbit, the spacecraft crosses periapsis at about the same local time every orbit. This can be useful if instruments on board depend on a certain angle of solar illumination on the surface. Mars Global Surveyor's orbit is a 2-pm Mars Local Time sun-synchronous orbit, chosen to permit well-placed shadows for best viewing. WebHere is a GIF of an animation I once made of a hypothetical ground track of a satellite in a similar to the ISS for example. I used math from the Technical Details subsection Wikipedia article Sun-synchronous_orbit including the precession of the nodes due to Earth's oblateness. It's a simple calculation and does not include many effects

WebNov 28, 2024 · A sun-synchronous orbit is a special type of a low-earth orbit. As the name suggests, it has something to do with syncing up with the sun. In this orbit, the satellite is placed in a way so that the angle between the orbital plane and the line joining Earth and the sun remains constant. Take a look at the image below to understand this arrangement. WebJan 1, 2004 · A Sun-Synchronous Orbit (SSO) is defined as the orbit whose normal (z axis) makes a constant angle with the Sun-Earth direction ( x E axis), hence, the key property ( z T x E = constant) of being ...
