Detailed explanation-1: -Sun-synchronous orbit (SSO) is a particular kind of polar orbit. Satellites in SSO, travelling over the polar regions, are synchronous with the Sun. This means they are synchronised to always be in the same ‘fixed’ position relative to the Sun.
Detailed explanation-2: -A Sun-synchronous orbit is useful for imaging, reconnaissance, and weather satellites, because every time that the satellite is overhead, the surface illumination angle on the planet underneath it is nearly the same.
Detailed explanation-3: -Geostationary orbit is a type of geosynchronous orbit. Geosynchronous orbits involve the satellite completing an orbital period in a single day. Sun-synchronous orbits are another type of orbit in which the satellite will always appear to follow the same path around the Earth from the perspective of the Sun.
