The following calculator is a very helpful tool to quickly and correctly calculate a satellite link budget, which is important to minimize interference caused by misaligned transmission levels. We wish to thank Eric Johnson of , the developer of this calculator.
Complete all green fields and then click any calculate button to obtain
results in the blue fields.
The following lead to pre-calculated satellite link budget with useful
default parameters inserted which may be amended and then recalculated.
For deep space link range radio range calculations this
is fun to
try.

No liability is accepted for any consequences of its use! Note that it is in two halves. You need to manually derive the downlink eirp from the uplink pfd based on a knowledge of the uplink and downlink beam patterns, the actual transponder gain setting and input and output back off operating point. The calculator works fine for real links if you know, and input, the correct parameters. Rubbish in = rubbish out!
