(a(i))[1]
State the direction in which the orbit is taken about the Earth.
(a(ii))[1]
State the satellite’s position in relation to the Earth’s surface.
(a(iii))[1]
State a representative frequency for communication between the satellite and Earth.
(b(i))[3]
A signal sent from Earth to a satellite starts with a power of $3.0\,\text{kW}$. The power received by the satellite is reduced by $195\,\text{dB}$. Calculate the signal power received by the satellite.
(b(ii))[2]
By reference to your answer in (i), explain why separate frequencies are used for the up-link and the down-link in communication with the satellite.
