  3. Satellite Interview Questions and Answers will guide us now that the satellite is an object which has been placed into orbit by human endeavor. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon. Satellites are used for a large number of purposes

Orbital plane and speed. The satellite has to be orbiting in the plane defined by the earth's equator otherwise it will 'wobble' north and south of its position. Its speed must be such as to complete one orbit every 24 hours, so it always stays ov.. Satellites orbiting the Earth are used for navigation, meteorology, astronomy and communication. The curved reflectors of satellite dishes allow signals to be sent and received over large distances

A geostationary satellite . 1. Revolves about the polar axis. 2. Has a time period less than that of the near-earth satellite. 3. Moves faster than a near-earth satellite. 4.

CARTOSAT is a group of geostationary satellites sent up by India. a) True. b) False. Answer: b. Clarification: INSAT is a group of geostationary satellites sent up by India for telecommunications, broadcasting, meteorology, and search and rescue. A geostationary satellite does indeed move, relative to any location on or within the Earth. The Earth is of course rotating. The satellite remains above a fixed location on Earth's equator, but that only means that the satellite and the spot on Earth's equator have the same angular velocity around Earth's axis. If you consider linear velocity at any given instant, the satellite and the spot. Recall that geostationary satellites are placed into an orbit which is designed to stay above a fixed point on the Earth's surface. If the Earth and the satellite were both spherical cows in an otherwise-empty universe, the satellite, once placed in orbit at geostationary altitude over the equator, would presumably co-rotate with the Earth for the rest of time

You can calculate the speed of a satellite around an object using the equation The satellite travels around the entire circumference of the circle — which is if r is the radius of the orbit — in the period, T. This means the orbital speed must be. Related questions +1 vote. 1 answer.

As the height of a satellite increases, so the time for the satellite to orbit increases. At a height of 35790 km, it takes 24 hours for the satellite to orbit. This type of orbit is known as a geosynchronous orbit, i.e. it is synchronized with the Earth. One particular form of geosynchronous orbit is known as a geostationary orbit Geostationary Satellite: These satellites are placed into orbit at a distance of around 35,800 km from the earth's surface. 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) 7000 miles per hour-we can calculate the radius of earth by dividing the circumference at the equator by 2 & 3.14. 24,901.55/2 = 12,450/ 3.14 = 3965 miles. if we add the distance the satellite is from the equator, we will determine the radius of the satellite: 3965 + 22,300 = 26,255 miles. we can then calculate the circumference of the satellite by multiplying its radius by 2 and 3.14: 26265.
