Sun-synchronous orbit - Wikipedia
WebA Sun-synchronous orbit (SSO), also called a heliosynchronous orbit, is a nearly polar orbit around a planet, in which the satellite passes over any given point of the planet's surface at the same local mean solar time.
Sun-Synchronous Orbit - Definition & Detailed Explanation
WebApr 21, 2024 · A Sun-Synchronous Orbit is a type of polar orbit used by satellites and spacecraft that allows them to pass over any given point on Earth at the same local solar time. This means that the satellite will always see the same portion of the Earth illuminated by the sun, regardless of the time of day.
Sun-synchronous — Science Learning Hub
WebA Sun-synchronous orbit matches the rate at which the Earth goes around the Sun. It is a low-Earth orbit. Advantage: consistent lighting conditions of the Earth’s surface enable us to compare images from the same season over several years. Altitude: typically 600–800 km. Satellite period: 96–100 minutes. Satellite examples: Landsat 7 ...

WebMar 30, 2020 · 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.
