What is the main difference between a geostationary and a polar satellite?

What is the main difference between a geostationary and a polar satellite?

Polar orbiting satellites provide imagery and atmospheric soundings of temperature and moisture data over the entire Earth. Geostationary satellites are in orbit 22,000 miles above the equator, spin at the same rate of the Earth and constantly focus on the same area.

What are the difference between the two types of orbit?

A circular orbit has an eccentricity of 0, while a highly eccentric orbit is closer to (but always less than) 1. A satellite in an eccentric orbit moves around one of the ellipse’s focal points, not the center. (NASA illustration by Robert Simmon.) Inclination is the angle of the orbit in relation to Earth’s equator.

What is the difference between geostationary satellite and?

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. While the geostationary orbit lies on the same plane as the equator, the geosynchronous satellites have a different inclination.

Why do satellites in lower orbits travel faster?

The gravitational attraction between two objects decreases with distance. The greater the acceleration, the greater the change in velocity – this causes the object to move faster. This means that objects in small orbits travel faster than objects in large orbits.

What are three advantages of geostationary satellites?

There are some advantages of geo-stationary satellites:

  • Get high temporal resolution data.
  • Tracking of the satellite by its earth stations is simplified.
  • Satellite always in same position.

What are the examples of polar satellite?

Polar satellites are usually used as earth observation purpose. Landsat, NOAA, SPOT, ERS are few examples of polar satellite.

What are the 3 types of satellites?

Types of Satellites and Applications

  • Communications Satellite.
  • Remote Sensing Satellite.
  • Navigation Satellite.
  • Geocentric Orbit type staellies – LEO, MEO, HEO.
  • Global Positioning System (GPS)
  • Geostationary Satellites (GEOs)
  • Drone Satellite.
  • Ground Satellite.

What is the most important application of geostationary satellite?

Communications. Geostationary communication satellites are useful because they are visible from a large area of the earth’s surface, extending 81° away in both latitude and longitude. They appear stationary in the sky, which eliminates the need for ground stations to have movable antennas.

What are the advantages of geostationary satellite?

The geostationary orbit is used by many applications including direct broadcast as well as communications or relay systems. The geostationary orbit has the advantage that the satellite remains in the same position throughout the day, and antennas can be directed towards the satellite and remain on track.

Do satellites run out of fuel?

The satellites, which are maintained in the proper position about 22,500 miles above Earth by firing small rocket thrusters, must be replaced shortly before they run out of fuel. Enough fuel must remain to get the satellites out of orbit to make room for their replacements.

What speed do geostationary satellites go?

The aptly titled geosynchronous orbit is described in detail: “At an altitude of 124 miles (200 kilometers), the required orbital velocity is just over 17,000 mph (about 27,400 kph). To maintain an orbit that is 22,223 miles (35,786 km) above Earth, the satellite must orbit at a speed of about 7,000 mph (11,300 kph).

How is a geostationary satellite different from a polar satellite?

A Geo-stationary satellite is a special type of geo-synchronous satellite and a polar satellite is a special type of sun-synchronous satellite. Geostationary Satellites have a circular orbit that lies in the plane of the earth’s equator.

Are there any polar orbiting satellites on Earth?

Complementing the geostationary satellites are two polar-orbiting satellites known as Advanced Television Infrared Observation Satellite (TIROS-N or ATN), constantly circling the Earth in an almost north-south orbit, passing close to both poles.

How are polar and infrared satellites different in resolution?

The main difference between the range of surface temperatures detected by the two satellites is due to their different spacial resolution: 1 km for the NOAA and 8 km for the GOES. The equivalent blackbody temperatures recorded by the GOES are 2–3°C lower than those obtained by the NOAA satellite because of a GOES calibration offset.

What’s the difference between Geo stationary and Geosynchronous satellites?

mainly used for earth mapping and spy satellites. Geo-stationary is equatorial – they stay over the same location (they’re in what has been called a Clarke Orbit, after Arthur C Clarke who popularized the concept). Most geosynchronous satellites are used for communications.
