What is the difference between GEO and GSO?

Objects in GSO have an orbital speed that matches the Earth’s rotation, yielding a consistent position over a single longitude. GEO is a kind of GSO. It matches the planet’s rotation, but GEO objects only orbit Earth’s equator, and from the ground perspective, they appear in a fixed position in the sky.

What is the difference between geostationary satellite and polar satellite?

In geostationary orbits, the satellite hovers over a fixed geographical location. Polar orbits are closer to Earth and move with respect to the Earth’s surface, crossing the poles several times each day and observing different longitudes on each pass (as shown in the figure below).

What is the difference between geostationary satellite and sun synchronous satellite?

Let us summarize difference between Sun synchronous orbit and Geosynchronous orbit. ➨Sun synchronous orbit is located at the altitude of 700 to 800 Km. Geosynchronous orbit is located at altitude of 35786 Km. Geosynchronous orbit period is one sidereal day which is about 23 hours, 56 minutes, and 4 seconds.

Why the satellites in Heo are called geostationary?

Description: When a geosynchronous satellite is placed directly above the Equator with a circular orbit and angular velocity identical to that of the Earth, the satellite is known as a geostationary satellite. These satellites appear to be stationary above a particular point which is due to the synchronization.

What is the difference between GPS and navigation system?

GPS Navigation Systems are used to locate addresses and provide directions to end destinations. A GPS Tracker like a Navigation System also receives data from the satellites. But unlike a navigation system, the tracker is meant to display information to someone who is hundreds of miles away.

What is the difference between geostationary and polar satellites write any two applications of geostationary satellite?

Polar satellite revolves around the poles or in the north-south direction around the earth but geostationary satellite revolves in the direction of the earth or east-west direction. 2. Geostationary satellite provides constant coverage of the area where polar satellite passes through the same point for 1-2 times a day.

What are the differences between polar orbit and geostationary orbit?

While polar orbits have an inclination of about 90 degrees to the equator, geostationary orbits match the rotation of the Earth. A sun-synchronous orbit passes by any given point with the same local solar time, which is useful for consistent lighting and sun angle.

How many geostationary satellites are needed for global coverage?

The current generation of geostationary meteorological satellite are truely technological marvels. 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.
