How is link budget calculated?
A simple link budget equation looks like this: Received power (dBm) = transmitted power (dBm) + gains (dB) − losses (dB)
What a satellite link budget is and how it is used?
In essence link budget is like a set of calculations giving the feasibility and performance summary of a particular communication link from the transmitter to the receiver end. In case of satellite, which is a moving object it is calculated for the whole region, from where you want to receive, typically a cone.
What do you mean by link budget in satellite communication?
A communication link budget is a way of accounting for all gains and losses in a communication system from transmitter output power to the power seen by the receiver. By knowing all the losses and gain in our communication system, we can predict how reliably the signal can be received.
Which of the losses are considered in satellite link design?
Antenna misalignment losses
The alignment of the earth station and satellite link antenna must provide maximum gain value. So, whenever there is some kind of mismatching in the alignment of the two then such losses are regarded as antenna misalignment losses.
