Who this section is for. Readers who want to understand a quantity rather than look it up. No prior RF or orbital background is assumed, but comfort with logarithms and trigonometry is.

These lessons build up the physics the rest of the site relies on. They are understanding-oriented: they explain why a number behaves the way it does, and deliberately do not double as reference material.

Available now

01. Decibels and the link budget

Why radio engineering works in logarithms, and how the terms combine into carrier-to-noise density.

Not yet published

Lessons 02 through 12 are ported in Phase 2: antennas and aperture, free-space path loss, slant range geometry, noise temperature and G/T, carrier to noise, modulation and BER, atmospheric and rain attenuation, Doppler shift, the full link budget, Walker constellations, and constellation design consolidation.
