Sun Synchronous Satellite Images

It is sun synchronous which means that the satellite always passes the same point on earth at the same local time.

Sun synchronous satellite images. Liftoff of the pslv c43 vehicle from from sdsc image credit. Thus it guarantees the same illumination condition which varies only with seasons. The satellite passes over a given location on earth every time at the same local solar time. An earth observation satellite or earth remote sensing satellite is a satellite used or designed for earth observation eo from orbit including spy satellites and similar ones intended for non military uses such as environmental monitoring meteorology map making and others.

Superview 1 satelllite sensor 0 5m is a chinese remote sensing satellite operated by beijing space view technology co. Sun synchronous orbit altitude of 636 6 km inclination of 97 957º. A sun synchronous orbit is useful for imaging spy and weather satellites because every time that the satellite is overhead the surface illumination angle on the planet underneath it will be nearly the same. Features of sun synchronous orbits.

At 800 km it will be travelling at a speed of approximately 7 5 km per second. This consistent lighting is a useful characteristic for satellites that image the earth s surface in visible or infrared wavelengths such as weather and spy satellites. The hysis minisatellite in deployed configuration image credit. These satellites orbit at an altitude between 700 to 800 km.

The most common type are earth imaging satellites that take satellite images analogous to aerial photographs. A satellite in a sun synchronous orbit would usually be at an altitude of between 600 to 800 km. As a satellite in a near polar sun synchronous orbit revolves around the earth the satellite crosses the equator at approximately the same local sun time every day. Orbit of passenger payloads.

The orbit is quasi polar in nature and so ensures coverage of the whole surface of the earth. The superview 1 satellite was launched on january 9 2018 03 24 utc on a long march 2d vehicle from tslc taiyuan satellite launch center in china. Sun synchronous orbit altitude of 504 5 km inclination of 97 468º. Satellites that take pictures of the earth would work best with bright sunlight.

Sun synchronous orbits these orbits allows a satellite to pass over a section of the earth at the same time of day. Because of the orbital velocity all other points on the globe are passed either slightly before or after this time.

These orbits are used for satellites that need a constant amount of sunlight.
