Where are sun synchronous satellites?
Sun-synchronous orbits are mostly selected for Earth observation satellites, with an altitude typically between 600 and 1000 km over the Earth surface.
What types of satellites use a sun-synchronous orbit?
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.
Is geostationary orbit Sun synchronous?
Geostationary orbit is a common kind of circular synchronous orbit. But exactly what is a geostationary orbit? Geostationary orbit involves a satellite orbiting above the Earth’s equator while its orbital period is equal to Earth’s rotational period or day.
How long is a sun-synchronous orbit?
A sun-synchronous orbit takes approximately an hour and a half to two hours before coming back to the same latitude and starting a new ascent.
Is sun-synchronous orbit circular?
Sun-Synchronous Circular Orbit, Inclination vs Altitude (LEO,J2 perturbed) | Small Satellites.
What are synchronous satellites called?
A satellite in a synchronous orbit that is both equatorial and circular will appear to be suspended motionless above a point on the orbited planet’s equator. For synchronous satellites orbiting Earth, this is also known as a geostationary orbit.
Are all polar orbits sun-synchronous?
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.
Is a sun-synchronous orbit circular?
What is the advantage of a sun-synchronous orbit?
Advantages of sun-synchronous orbits The near polar orbit allows a global coverage for the observation of the whole Earth. Orbit altitudes of between 700 and 900 km permits both a large ground swath, offering a daily global coverage, and a good ground resolution.
What altitude is sun-synchronous orbit?
between 600 to 800 km
Often, satellites in SSO are synchronised so that they are in constant dawn or dusk – this is because by constantly riding a sunset or sunrise, they will never have the Sun at an angle where the Earth shadows them. A satellite in a Sun-synchronous orbit would usually be at an altitude of between 600 to 800 km.
Is sun-synchronous orbit same as polar orbit?
Polar orbits are a type of low Earth orbit, as they are at low altitudes between 200 to 1000 km. Sun-synchronous orbit (SSO) is a particular kind of polar orbit.
Can a sun-synchronous satellite see the poles?
These satellites, however, do not see the poles at all, and to get global coverage of just the equatorial regions, you need a network of 5-6 satellites. A satellite in lower Earth orbits is better positioned to obtain high quality remote-sensing data.
Which is the latest satellite of India placed in the geosynchronous orbit?
GSAT-8 is presently located at 47 deg East longitude and is being moved towards its final orbital position of 55 deg East where it will be co-located with INSAT-3E satellite.
How many types of satellites are there in India?
Currently, eleven operational satellites are in orbit – RESOURCESAT-1 and 2, CARTOSAT-1, 2, 2A, 2B, RISAT-1 and 2, OCEANSAT-2, Megha-Tropiques and SARAL….Hemant Singh.

What is difference between geosynchronous and geostationary?
While geosynchronous satellites can have any inclination, the key difference from geostationary orbit is the fact that they lie on the same plane as the equator. Geostationary orbits fall in the same category as geosynchronous orbits, but it’s parked over the equator.
What is the difference between geostationary satellite and sun-synchronous satellite?
➨Sun synchronous orbit is located at the altitude of 700 to 800 Km. Geosynchronous orbit is located at altitude of 35786 Km. ➨Orbital period of sun synchronous satellite is about 100 minutes. Geosynchronous orbit period is one sidereal day which is about 23 hours, 56 minutes, and 4 seconds.
