AMSAT-UK provides a template of excel sheet that can be used for calculating link budget of satellite signals, by tweaking with known data. Pasternack's Link Budget Calculator determines the received signal strength (in dBm) given a systems amplifier gains, antenna gains and space loss. I am not an Excel expert, but here are all useful spreadsheets I have collected and created. The Link Budget Spreadsheet helps users of Maxim's industrial, scientific, and medical radio-frequency (ISM-RF) products (Tx, Rx, TRx) estimate the range and link margin that they can achieve with a given radio design in several representative environments. Satellite link budget calculator below is an excel template to help satellite engineers calculating performance in terms of signal values based on particular antenna size, power requirements and many other factors. parameters to match your system requirements. spec e.g -80 dBm), Receive margin dB It has antenna model consideration that you might need when selecting the correct antenna based on calculated link budget in this spreadsheet. That’s what engineers do behind satellite companies.
