Sun-synchronous orbit: - It is a particular kind of polar orbit.
- Satellites in SSO, travelling over the polar regions, are synchronous with the Sun.
- They are synchronized to always be in the same ‘fixed’ position relative to the Sun.
- The satellite always visits the same spot at the same local time. For example, passing the city of Paris every day at noon exactly.
- The satellite will always observe a point on the Earth as if constantly at the same time of the day, which serves a number of applications.
