What is the altitude of geostationary satellite?
A geostationary satellite is in an orbit that can only be achieved at an altitude very close to 35,786 km (22,236 miles) and which keeps the satellite fixed over one longitude at the equator.
What are the conditions for geostationary satellites?
Three conditions are required for an orbit to be geostationary: The satellite must travel eastward at the same rotational speed as the earth. The orbit must be circular. The inclination of the orbit must be zero.
How do you find the altitude of a geostationary orbit?
From Newton’s Second law of Motion, the centripetal force Fc is given by: . The resulting orbital radius is 42,164 kilometres (26,199 miles). Subtracting the Earth’s equatorial radius, 6,378 kilometres (3,963 miles), gives the altitude of 35,786 kilometres (22,236 miles).
Why is a geostationary satellite placed at height 36000 km?
1 GEO. GEO satellites orbit the earth at a fixed distance of 35,786 km. The speed of the satellite at this distance matches the earth’s rotation, thereby keeping the satellite stationary over a particular point on the earth.
What is the height of a geostationary orbit from the surface of Earth?
The approximate height of a geostationary satellite from the earth’s surface is 35786 km. A geostationary orbit is a circular orbit. It is above the earth’s equator. A satellite in a geostationary orbit appears stationary.
What is the period of geostationary satellite?
about one day
Geostationary satellite is one of the artificial satellites, which revolves around Earth’s equator above 22,236 miles in a geostationary orbit. It has an orbital period equal to Earth’s rotational period of 23 hours and 56 minutes, which is about one day on earth.
What are geostationary satellite give its condition and uses?
A satellite which appears to be stationary to an observer standing on the earth is known as a geostationary satellite. The conditions for satellite to appear stationary are: (i) The time-period should be 24 hours. (ii) Its orbit should be in the equatorial plane of the earth.
Why are geostationary satellites stationary?
A geostationary satellite is launched in such a way that it follows an orbit parallel to the equator and travels in the same direction as the earth’s rotation with the same period of 24 hours. Thus, it appears stationary with respect to the earth surface.

What is difference between geostationary and geosynchronous orbit?
While geosynchronous satellites can have any inclination, the key difference to 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.
Why are geostationary satellites above the equator?
Satellites in geostationary orbit rotate with the Earth directly above the equator, continuously staying above the same spot. This position allows satellites to observe weather and other phenomena that vary on short timescales.
What is the potential at a height of 36 000 km from the earth’s surface?
3) What is the potential at a height of 36 000 km from the Earth’s surface? This is the height of a geostationary orbit. What is the potential difference between the surface of the Earth, and geostationary orbit height? The potential difference is then – 9.4 – (- 63) = 53 MJ kg-1 (or 5.3 x 107 J kg-1).
What is the altitude of a geostationary satellite?
A geostationary satellite is in an orbit that can only be achieved at an altitude very close to 35,786 km (22,236 miles) and which keeps the satellite fixed over one longitude at the equator. The satellite appears motionless at a fixed position in the sky to ground observers.
How are geostationary satellites launched from Earth?
The classic procedure for launching a geostationary satellite falls into three phases. In the first phase (boost phase) a powerful two stage liquid propellant rocket (the booster) places the satellite and the necessary upstage rockets in an orbit about 200km above the ground.
How can geostationary satellites be used to augment GNSS?
Geostationary satellites can be used to augment GNSS systems by relaying clock, ephemeris and ionospheric error corrections (calculated from ground stations of a known position) and providing an additional reference signal.
What are the advantages of geostationary satellites?
They could handle a much larger data stream than the polar low Earth orbiters making it possible to collect both data and more recently accurate geolocation information from GPS receivers. Today geostationary satellites are the primary observing platforms for all weather forecasting operations.
