Carries 3 Marks Class 11 CBSE Ask for details ; Follow Report by Sarah92 19.01.2020 Log in to add a comment Geostationary orbit, a circular orbit 35,785 km (22,236 miles) above Earth’s Equator in which a satellite’s orbital period is equal to Earth’s rotation period of 23 hours and 56 minutes. 5. The equivalent brightness temperature T b recorded by geosynchronous infrared (geo-IR) “window” channel (10.7–11.5 μm) satellite sensors is shown to depend on the zenith angle (local angle from the zenith to the satellite for a pixel’s ground location) in addition to the mix of clouds and surface that would be observed from a direct overhead viewpoint (nadir view). A typical polar orbiting meteorological satellite, at an altitude of about 850 km, sees a relatively small portion of the globe at any one time. Each planet revolves around the sun in an elliptical orbit with the … This particular orbit is used for meteorological and communications satellites. What is a geostationary satellite? Segmentation and Tracking of Marine Cellular Clouds observed by Geostationary Satellites Alisa Gufana,b, Yoav Lehahna, Erick Fredjc,d, Colin Priceb, Rachel Kurchine and Ilan Korena aDepartment of Earth and Planetary Sciences, Weizmann Institute of Science, Rehovot, Israel; bDepartment of Geosciences, Tel Aviv University, Ramat Aviv, Israel; cDepartment of Computer Sciences, The Jerusalem Eccentricity appears as daily longitudinal oscillations about the nominal location of the geostationary satellite as observed from a position on the Earth. This web site provides capabilities for finding and obtaining those data. What are the basic requirements for such a satellite? 2) These satellites must travel in the rotational speed of earth, and in the direction of motion of earth, that is eastward. For instance, the Advanced Geosynchronous Radiation Imager (AGRI) aboard FY-4A (AGRI/FY-4A) takes full-disk images at a 15-min interval in 14 spectral bands with the 0.5–4-km resolution. 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. They rotate in the same direction as the earth and one revolution of such satellites is the same as one day on earth (roughly 24 hours). (a) It must always be stationed above the equator. Gravitation Class 11 Notes Physics Chapter 8 • Kepler’s Laws of Planetary Motion Johannes Kepler formulated three laws which describe planetary motion. Gravitation. By Jagran Josh NCERT Easy … By comparing collocated GPI derived from geostationary satellite limb views (zenith angles 22°–59°) with GPI derived from geostationary satellite nadir views (zenith angles < 22°), they determined a GPI correction that decreased the precipitation estimates at a linear rate of 9% per 10° of zenith angle for zenith angles larger than 26°. Meanwhile, LEO satellites revolve at an altitude between 160 to 2,000 kilometers (99 to 1,200 miles). 6. Name a polar satellite… GEO-KOMPSAT-2 (Geostationary - Korea Multi-Purpose Satellite-2) Program / Cheollian-2 / GK-2. A geostationary satellite is orbiting the earth at a height of 5R above that surface of the earth, R being the radius of the earth. CBSE Class 11: Gravitation – Orbital Speed In this video we will learn about the Orbital Speed of a satellite, Energy of a Satellite, and Time Period of a Satellite. (d) Its orbit must be circular, and not elliptical. From geostationary altitude, the entire Earth disk only subtends an angle of 17.4 degrees. This document is highly rated by Class 11 students and has been viewed 2580 times. ... called geostationary or parking satellite. As the earth rotates to the east beneath the satellite, each pass monitors an area to the west of the previous pass at intervals of roughly 90 to 100 minutes.
