A geostationary satellite is a satellite located in an orbit
such that it remains above the same
point on the Earth’s surface. [Assume it takes 23 hours 56 minutes
4.09 seconds for the Earth
to spin around once.]
a) What is the angular velocity of such a satellite?
b) What is the altitude of such a satellite?
c) Calculate the period of a satellite orbiting 200km above the
Earth.

A geostationary satellite orbit having a radius of 67 E6 m is established around a planet whose mass is 5.5 E24 kg. Determine the period of the orbit in earth-hours.
A satellite in geostationary orbit appears to remain stationary in the sky as seen from any particular location on Earth. a. At what altitude would such a satellite need to be above the Earth? Use 4pi^2r/T^2 where T is the period. Use the 2nd equation and mathematial insight 4.5 on p. 131 ro find r for T=1 day (The Cosmic Perspective)
For communications purposes, satellites are typically placed in a circular geosynchronous orbit. If the orbit is in the equatorial plane of the Earth, it is called geostationary. A satellite’s orbital speed in a geostationary orbit is set to match the angular velocity Ωe of the rotating Earth (with mass M), so that as seen from the Earth the satellite is stationary above a fixed point on the Equator. For a satellite of mass m in a geostationary circular orbit then...
10-3. A 639-kg satellite is in a circular orbit about Earth at a height h = 1.16 x 10^7 m above the Earth’s surface. Find (a) the gravitational force (N) acting on the satellite, (b) the satellite’s speed (m/s) (magnitude of its velocity, not its angular velocity), and (c) the period (h) of its revolution. Caution: The radius of the satellite’s orbit is not just its height above the Earth’s surface. It also includes the radius of the Earth. The...
A satellite is in orbit around Earth at a height of 120 km above Earth’s surface. Find the orbital speed of the satellite. (Mass of the earth is 6*1024 kg and the radius of Earth is 6371 km)
7. An antenna on the Earth's surface sends a signal as a plane-wave to a satellite orbiting the Earth at the geostationary orbit. Assume the antenna on the satellite is A m2 across. Assuming (though incorrect) the Earth's atmosphere and outer space both to be a lossless media, what is the expression of the ratio of the power transmitted versus power received in dB? Assuming the Earth's atmosphere and outer space together present an average attenuation, what does the ratio...
A satellite travels around Earth in uniform circular motion at an altitude of 35,850 km above Earth’s surface. The satellite is in geosynchronous orbit. In the below figure, the satellite moves counterclockwise (ABCDA). (State directions in terms of the x- and y-axes.) The radius of Earth is 6371 km. What is the direction of the satellite’s average velocity for one quarter of an orbit, starting at A and ending at B? Enter the answer in degrees where negative indicates an...
a satellite in a geosynchronous orbit remains above the same point on Earth 2. A satellite in a geosynchronous orbit remains above the same point on Earth provided it orbits in the equatorial plane in the same direction as Earth's rotation. (a) Calculate the speed of a satellite in such an orbit. (b) Calculate the total energy of a satellite in such an orbit.
[2pt] A spy satellite is in circular orbit around Earth. It makes one revolution in 5.99 hours. How high above Earth’s surface is the satellite?
A satellite is in a circular orbit around the Earth at an altitude of 2.24 x 106 m. (a) Find the period of the orbit. (Hint: Modify Kepler's third law so it is suitable for objects orbiting the Earth rather than the Sun. The radius of the Earth is 6.38 x 106 m, and the mass of the Earth is 5.98 x 1024 kg.) h (b) Find the speed of the satellite. km/s (c) Find the acceleration of the satellite....
