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

(1/2)Gm/R2=Gm/(R+h)2Where:G is the gravitational constantm is the mass of the EarthR is the Radius of the Earthh is the height above the Earth where Gravity is 1/2 surface gravityCanceling Gm from both sides gives:1/2R2 = 1/(R+h)2inverting to make things simpler:2R2 = (R+h)2taking the square root of both sides:sqrt(2)R=R+h(sqrt(2)-1)R=hthe sqrt(2)=1.4142135623730950488016887242097(sqrt(2)-1) = 0.4142135623730950488016887242097so h=0.4142 RThe required height is 0.41 times the radius of Earth.

What is the transmission from a satellite to an earth-based station?

The transmission from a satellite to an earth-based station is typically done using radio frequency signals. The satellite sends data to the ground station through a process called downlinking. The ground station receives the signals, processes the data, and distributes it to its intended destination.


What type of satellite is the international space station?

The International Space Station (ISS) is a space station and not a satellite. Satellites typically orbit Earth independently, while the ISS serves as a habitable artificial satellite where astronauts live and conduct research in low Earth orbit.
