VIIRS and MODIS Aqua typically provide two observations per day, sometimes … Polar orbits are a type of low Earth orbit, as they are at low altitudes between 200 to 1000 km. the geostationary satellites have orbits parallel to the equator. This particular orbit is used for meteorological and communications satellites. The term geostationary comes from the fact that such a satellite appears nearly stationary in the sky as seen by a ground-based observer. According to you, a person standing at the south pole is inverted, still, he is not falling back why? The footprint of a geo-stationary satellite is from 75 degree north to 75 degree south latitude. This makes geostationary satellites ideal as communication and broadcasting satellites. Kinetic Energy. This video is highly rated by JEE students and has been viewed 549 times. What is the difference between a geostationary satellite and a polar satellite? This energy is provided by its orbit. A polar orbiting satellite closely parallels the earth's meridian lines, thus having a highly inclined orbit close to 90°.It passes over the north and south poles each revolution. At a height of about 35,786 Kilometers, the time period required is exactly 24 Hours. Geostationary satellite resolution is at best 1 km, with polar a little better at 250m. We all know the reason that it is due to gravity. (ii) Its orbit should be in the equatorial plane of the earth. The polar satellite is installed in a low earth orbit. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. At this altitude, one orbit takes approx. What is the difference between polar and geo stationary satellites? Since the field of view of a satellite in geostationary orbit is fixed, it always views the same geographical area, day or night. NCERT solutions for class 11 physics chapter 8 gravitation solved by subject matter experts. The orbits are circular, with an alitude between 830 (morning orbit) and 870 (afternoon orbit) km, and are sun synchronous. Cell phones, television and GPS tracking systems can all work using a satellite system, but understanding the difference between Low Earth Orbit Satellite (LEO’s) and Geostationary Satellites (GEO’s) can help one determine which of the […] 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. Uses: weather forecasting satellite television satellite radio etc. 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. This web site provides capabilities for finding and obtaining those data. At this height, the satellite's orbital period matches the rotation of the Earth, so the satellite seems to stay stationary over the same point on the equator. 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. A satellite in a polar orbit passes over both poles on each orbit. like wise geostationary statellites are those with equtorial orbits and polar statellites are those with polar orbits. Join now. [ top ] This special position in high Earth orbit is known as a geosynchronous orbit. As the Earth-satellite system is a bound system, the total energy of the satellite is negative.
