### Inter-satellite/Inter-platform communication requirements

I am studying Inter-satellite/Inter-platform links and would like to compute the link budget: Satellite-Satellite or HAP to HAP ( high altitude platform). For my computation, I am looking for a ...

I have seen an answer here how we can compute link budget in satellite communication. Link Budget $$P_{RX} = P_{TX} + G_{TX} - L_{FS} + G_{RX}$$ $P_{RX}$: received power by spacecraft $P_{TX}$: ...

### How to compute each of these link budget terms?

The terms in Equation are all in decibels (dB), which is logarithmically scaled. In Equation, $P_{rx}$ is the received peak power, $P_{tx}$ is the transmitted peak power, $G_{tx}$ is the transmitter ...

### Impact of having two antennas on link budget calculations

I'm working on link budget of a cubesat mission that needs to have two dipole antennas that are perpendicular to each other. I want to know if having two antennas affect the link budget? losses, and ...
