like wise geostationary statellites are those with equtorial orbits and polar statellites are those with polar orbits. Polar-orbiting satellites enable long-term monitoring of the entire Earth, tracking atmospheric variables such as temperature and providing atmospheric data and cloud images. Telecommunication needs to "see" their satellite all time and hence it must remain stationary in the same positions relative to the Earth's surface. Difference between geostationary and geosynchronous satellite. They are very useful in applications where the field vision of the entire earth is required in a single day. Following a nearly circular path around the Earth, polar-orbiting satellites track atmospheric conditions that eventually affect the weather and climate of the United States. This makes geostationary satellites ideal as communication and broadcasting satellites. Geostationary satellite resolution is at best 1 km, with polar a little better at 250m. There’s a sweet spot above the Earth where a satellite can match the same rotation of the Earth. As the name suggests polar satellites orbit the Earth from pole to pole, often in a low down with an orbit time of 90 minutes.

CAPTION: This illustration shows the true relative distances from the Earth of geostationary and polar orbiting satellites. 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).At this altitude, one orbit takes 24 hours, the same length of time as the earth requires to rotate once on its axis. Geostationary satellites have larger fields of view due to large incidence angles, rawer resolutions, and broader band widths in comparison with polar-orbiting satellites, which offer higher spatial resolution and near-nadir views. 8.12 Weightlessness. Geostationary Orbit. 2) A satellite in a polar orbit is just one with an orbit that takes it over the north and south poles. Signals from these satellites can be sent all the way round the world. These satellites are often taking regular photographs and are widely used for such things as weather forecasting, crop surveys, oceanography and of course for military spying. Ask your question. A geotationary 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). A polar orbit is that orbit whose angle of inclination with equatorial plane of earth is 90°. As the satellite is in orbit, the Earth is rotating beneath it. These are those satellites which revolve in polar orbits around earth. In this Physics (Gravitation) video lecture in Hindi for class 11 we explained the working of geostationary satellite and also calculated the height or altitude of that. It's at a special height such that it takes 24 hours to orbit Earth, and since Earth itself rotates on its axis once every 24 hours, the geostationary satellite appears to stay motionless above one spot on Earth (but really both are moving). Polar satellites circle at a low altitude, between 200 and 1000 km above the surface, as compared to an altitude of around 35,800 km for geostationary satellites.This means that polar satellites can take much higher resolution images that geostationary satellites. Satellites in a polar orbit do not have to pass the North and South Pole precisely; even a deviation within 20 to 30 degrees is still classed as a polar orbit. It's at a special height such that it … Since the field of view of a satellite in geostationary orbit is fixed, it always views the same geographical area, day or night. They can photograph the whole of the surface of the Earth in 24 hours as it rotates beneath them. A spacecraft in this orbit appears to an observer on Earth to be stationary in the sky. Its height is 500-800 km from the earth. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. At a height of about 35,786 Kilometers, the time period required is exactly 24 Hours. Sun-synchronous orbit (SSO) is a particular kind of polar orbit. Meanwhile, LEO satellites revolve at an altitude between 160 to 2,000 kilometers (99 to 1,200 miles). Energy of an orbiting satellite; Geostationary Satellite; Polar Satellites; Weightlessness; Class 11 Physics Gravitation: Polar Satellites: Polar Satellites. Figure 3Time series of spatially summed FRP for eastern China, as retrieved from geostationary Himawari, and polar-orbiting VIIRS-IM and MODIS observations made on 11 June 2015. POES and GOES both share a long-lasting legacy of image collection. (b)An orbiting satellite acquires a certain amount of energy that enables it to revolve around the Earth. Geo Synchronous Satellite It is parked in space 35,790 km above the equator of the stationary earth. m= mass of the satellite, v=velocity of the satellite; E.=1/2mv 2 =1/2 m (GM e /R e +h) by using (1) E. =1/2 GM e /(R e +h) E.= -GM e m/(R e +h) Total Energy = K.E. At this altitude, one orbit takes 24 hours, the same length of time as the earth requires to rotate once on its axis. A Polar satellite is a special type of sun-synchronous satellite.
