Why geostationary satellites require to transmit the TV signals?
If a satellite appears to move in the sky, then the ground station antenna has to keep moving in order to follow it, and the satellite will be below the horizon, invisible, and unusable for half the time over the long run. That would really put a crimp in the operation of all the little 2-ft satellite TV dishes on top of garages.
Explain why there is only one geostationary orbit?
There is only one geostationary orbit because in order for any mass m to orbit the Earth (ME) the gravitational force: EQ1: Fg = GmME/r^2 has to be such that it is equal to the required centripetal force for uniform circular motion: EQ2: Fc = mv^2/r where v is the velocity of m at radius r (distance from the center of the Earth) and: EQ3: v = 2(pi)(r)(f) f is the frequency of rotation in revolutions per second. For geostationary orbit the satellite must be in a fixed position (it must have the same frequency of rotation or angular velocity as the Earth's rotation) relative to the Earth and orbit above the Earth's equator. The necessary velocity to satisfy Fg = Fc is a specific value, therefore (since pi and f are fixed values) r is the only variable in EQ3. There is a specific orbital radius for geostationary orbit of any mass m.
What is the Round Trip time of a RF signal for GEO satellites?
the speed of light = 299792458 m / sGEO (Geostationary Earth Orbit) = 35863000 m above the Earth's surfaceround trip time = 2*(35863000)/299792458 =0.239 sthe time needed for an RF signal to reach a GEO satellite and gets retransmitted back to a ground station on earth is approximately 240 milliseconds(assuming zero signal propagation/processing time in the satellite and equatorial ground station location with the same longitude as the satellite slot)
Different types of satellite?
Answer: 1.communication satellite 2.navigational satellite 3.weather satellite 4.millitary satellite 5.scientific satellite 6.satellite launches. It composed of 6 satellites...........i hope.....my answer can help you.....
How many minimum number of geostationary satellite needed for uninterrupted global coverage?
In theory, 2 satellites in diametrically opposite geosynchronous orbits could cover the planet. In order for the satellites to communicate, a minimum of 3 would be needed, each at a 60 degree angle to the others. At this point, the strength and quality of coverage increases proportionally to the number of satellites.
How long does it take earth satellite 42250km from earth take to orbit once?
this is if it is not a geostationary orbit, in which case it is always in the same place relative to earth. imagine a circle of radius 42250km+radius of earth(6,356km). it's perimeter is 2 x pi x 48606km = satellite's journey. then think of a really fast speed, which is the speed the satellite is moving at. divide the distance by speed and you have the time of one orbit However, by the height being 42250 , it makes me think the satellite is a geostationary satellite and so it would take 24 hours moving at approximately 12725 kmph does that answer your question?

What are the Satellite in the Philippines?
The Philippines has multiple satellites in orbit for various purposes such as communication, weather monitoring, and earth observation. Some examples include DIWATA-1 and DIWATA-2, the Philippine Scientific Earth Observation Microsatellite (PHL-Microsat), and Agila-2, a geostationary communications satellite.

What is the distance between -2 4 and 1 -2?
What is the distance between (4, -2) and (-1,6)?
what is the distance between -2 and -1 1/2?
What is the distance between (4, -2) and (-1,6)?
What happens to the size of the centripetal force due to gravity acting on the satellite if the satellite moves farther from earth?
The centripetal force due to gravity decreases as the satellite moves farther from Earth because the force of gravity weakens with distance. This is in accordance with the inverse square law, which states that the force of gravity decreases with the square of the distance between two objects.
What is the distance between 4 -2 and -1 6?
What is the distance between (4, -2) and (-1,6)?
What is the advantages and disadvantages of satellite telecommunication system?
1) The coverage area of a satellite greatly exceeds.2) Transmission cost of a satellite is independent of the distance from the center of the coverage area. 3) Satellite to satellite communication is very precise. 4) Higher bandwidths are available for use.

How can you find the distance between two numbers on a number line?
Just subtract the lowest number from the greatest number. For example, the distance between 3 and 8, is 8 - 3 = 5 units, the distance between -2 and 3, is 3 - (-2) = 3 + 2 = 5 units, the distance between -4 and -2, is -2 - (-4) = -2 + 4 = 2 units.
What is the distance formula between 2 6 and 5 2?
(Distance)2 = (2 - 5)2 + (6 - 2)2
