A satellite is projected vertically from an Earth station at what height above the Earth's surface will the force of Earth's gravity on the satellite be only half its value at the earth station?

To answer this question we need to know either the height of the Earth station above the Earth or the gravitational acceleration of gravity present at the Earth station initially.
Solving without these values:
(1/2)Gm/R2 = Gm/r2
where
G is the Gravitational Constant
m is the mass of the Earth
R is the radius of the Earth Station from the center of the Earth.
r is the radius of the satellite where gr=1/2ge
2R2 = r2
SQRT(2)R=r

What is coverage angle in satellite communication?
The coordinates to which the earth station antennas must be pointed to communicate with the satellite is called Look angles.There r 2 types of look angles:1. Azimuth angle: Measured eastward from geographic north to the projection of satellite path on the local horizontal plane at the earth station.2.Elevation Angle: Measured upward from local horizontal plane at the earth station to the satellite path.

What is slant range in satellite communication?
Slant range is the LOS (line of site ) distance between the earth station and the satellite and it is very important in satellite link calculation .For instance to calculate the pathloss slant range would be used.Furthermore slant range is a means to describe the satellite location above the surface of the earth.

How does weightlessness occur?
When a force is present to oppose that of gravity. eg > Upthrust on a body in a liquid (body in a swimming pool) Centripetal force ( orbiting satellite or space station)
