A Sun-synchronous orbit (SSO), also called a heliosynchronous orbit, [1] 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.

2024年4月21日 · 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.

2020年3月30日 · Sun-synchronous orbit (SSO) is a particular kind of polar orbit in which satellites are in sync with the Sun. Matching Earth’s rotation around the Sun, they always appear in the same position relative to our star.

2013年3月27日 · A 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 ...

2024年11月4日 · Sun Synchronous Orbits. A walking orbit whose parameters are chosen such that the orbital plane precesses with nearly the same period as the planet’s solar orbit period is called a Sun synchronous orbit. In such an orbit, the spacecraft crosses periapsis at about the same local time every orbit.

A 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.

2020年3月2日 · 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.

Sunsynchronous orbits are typically Low Earth Orbits (LEO) used for remote sensing. LEO orbits are typically between 400 km and 800 km above the earth’s surface. Properties include: Low altitude for better image resolution. The Altitude is high enough to limit atmospheric drag. Low eccentricity for uniform resolution.

A sun-synchronous orbit (sometimes incorrectly called a heliosynchronous orbit) is a geocentric orbit which combines altitude and inclination in such a way that an object on that orbit passes over any given point of the Earth's surface at the same local solar time.

Generally, sun-synchronous orbits are medium or low orbits. Radarsat is an example of a satellite in a low sun-synchronous orbit. Radarsat is in orbit 798 kilometres above the Earth, at an angle of inclination of 98.6 degrees to the equator as it circles the globe from pole to pole.
