Topic: Link Budget
Question: what is the given formula used for? {p}_{r}=\frac{{p}_{r}{g}_{t}{g}_{r}{c}^{2}}{(4\pi)^{2}{R}^{2}{f}^{2}}
Option 1: The link between the satellite and Earth station is governed by the optical free-space propagation equation, rather than the basic microwave radio link equation.
Option 2: It is the link between the satellite and Earth station is governed by the basic microwave
radio link equation.
Option 3: The link between the satellite and Earth station is governed by the basic microwave radio link equation only for uplink signals, not for the downlink.
Formula: {p}_{r}=\frac{{p}_{r}{g}_{t}{g}_{r}{c}^{2}}{(4\pi)^{2}{R}^{2}{f}^{2}}
