State with reasons whether the following sentences are true or false. A low Earth orbit (LEO) is an Earth-centred orbit with an altitude of 2,000 km (1,200 mi) or less (approximately one-third of the radius of Earth), or with at least 11.25 periods per day (an orbital period of 128 minutes or less) and an eccentricity less than 0.25. Polar-Orbiting Satellites A disadvantage of geostationary satellites is that their large distance from the earth's surface compromises their ability to capture fine detailed resolution of the planet surface.Satellites put in low earth orbit, typically 850 km (531 miles) above the surface, can resolve topographic and other environmental … Polar orbits are often used for earth-mapping, earth observation and reconnaissance satellites, as well as some weather satellites. Mass of the satellite = 300 kg, Mass of the earth = 60 x 10 24 kg, Radius of the earth = 6.4 x 10 6 m G = 6.67 x 10-11 Nm 2 /kg 2. The height of geostationary satellite from the surface of the earth is 36000 km. Since the earth's surface is 6.37 x 10 6 m from its center (that's the radius of the earth), the satellite must be a height of. The POES satellite system offers the advantage of daily global coverage, by making nearly polar orbits 14 times per day approximately 520 miles above the surface of the Earth. If we wish to put a satellite into a geostationary orbit then it must orbit in the same 24 hours (86,400 seconds) that the Earth takes to spin once on its axis. Depending on the ground swath of the satellite, it is possible to adjust the period (by varying the altitude), and thus the longitudinal displacement, in such a way as to ensure the observation of any point on the Earth within a certain time period. The period of the satellite’s orbit is E 3 E Gm r 2 Gm r 2 r v 2 r T = π = π π = .
