Satellite that appears to be located at a fixed point in space when viewed from the earth's surface. Satellites located in geosynchronous orbit move in time with the rotation of the earth. Geostationary satellites are located 22,237 miles above the earth's surface.
What do you mean by polar satellite?
Polar Satellite - A polar orbit is one in which a satellite passes above or nearly above both poles of the body being orbited on each revolution. It therefore has an inclination of (or very close to) 90 degrees to the equator.
What are geostationary and polar satellites give one use for each?
Polar satellites are used for spy satellites mapping satellites and weather satellites. Geostationary satellites are satellites which orbit the Earth once per day. They therefore roughly stay over the same part of the planet all the time.
What is geostationary satellite class 11?
Geostationary satellites are Earth's satellites that are placed into orbit at a distance of around 35,800 km from the earth's surface. Geostationary satellites turn in the same direction as the Earth. Their one revolution is the same as one day on Earth.
What are geostationary and polar satellites Class 11?
Solution. Geostationary Satellite: It is the satellite which appears at a fixed position and at a definite height to an observer on earth. Polar Satellite: It is the satellite which revolves in polar orbit around the earth.
What are polar satellites give examples?
Polar satellite: It is a satellite that revolves around the earth in its polar orbit (perpendicular to the equatorial plane). As the earth rotates about its axis, a polar satellite successively passes through different points on the earth's surface, hence scanning the entire earth. Examples are: SPOT, IERS, etc..Dec 5, 2018
What are polar satellites 11th?
These are low altitude satellites. This means they orbit around earth at lower heights. They orbit around the earth in North-South direction. Whereas earth is moving from East to West.

What is polar satellite?
what do you mean by polar satellites? Polar satellite is a satellite whose orbit is perpendicular or at right angles to the equator . or in simple words it passes passes over the north and south poles as it orbits the earth .
How often do geostationary satellites orbit the Earth?
Geostationary satellites are just what it says. They look like they are standing still in the sky, but they actually are orbiting the Earth once every 24 hours, the same time it takes the Earth to make one rotation. Click to see full answer.
What is polar orbit?
Polar orbits are often used for Earth-mapping, Earth observation, capturing the Earth as time passes from one point, reconnaissance satellites, as well as for some weather satellites. The Iridium satellite constellation also uses a polar orbit to provide telecommunications services.
Geostationary Satellite - definition
A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers (22,300 miles) directly over the equator, that revolves in the same direction the earth rotates (west to east).#N#Application: Geostationary satellites appear to be fixed over one spot above the equator.Receiving and transmitting antennas on the earth do not need to track such a satellite.
Polar Satellite - definition
NASA science spacecraft designed The Global Geospace Science (GGS) Polar Satellite to study the polar magnetosphere and aurora Sensors on the spacecraft.
What are the two types of weather satellites?
There are two types of weather satellites: polar orbiting and geostationary. Both satellite systems have unique characteristics and produce very different products.The two polar orbiting satellites, in their north-south orbits, observe the same spot on the Earth twice daily, once during the daylight and once at night.
What is the weather satellite?
Weather Satellites are an important observational tool for all scales of NWS forecasting operations. Satellite data, having a global view, complements land-based systems such as radiosondes, weather radars, and surface observing systems. There are two types of weather satellites: polar orbiting and geostationary.
How far above the equator are satellites?
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. This enables the satellite to take a picture of the Earth, at the same location, every 30 minutes.
How often does Goes 16 scan?
GOES-16 can multi-task. The satellite will scan the Western Hemisphere every 15 minutes, the Continental U.S. every five minutes, and areas of severe weather every 30-60 seconds, all at the same time. GOES-16 can provide images of severe weather as frequently as every 30 seconds!
