Crate linkbudget 

A link budget toolbox for satellite communications.

This crate provides tools for calculating link budgets, including path loss, receiver sensitivity, BER curves, modulation schemes, EVM, orbital mechanics, and Doppler analysis.

Use linkbudget for end-to-end radio link performance: EIRP, FSPL, receiver G/T, C/No, SNR, Eb/No, BER, margins, modulation/FEC, PFD, Doppler, orbit geometry, sensitivity, EVM, and quantization. Use touchstone for .sNp S-parameter files, gainlineup for ordered block-level gain/NF/P1dB/IP3 lineups, and rfconversions for scalar RF conversions.
