1. ITU-R Recommendation P.322 β€” "Propagation data relevant to satellite service design"

Provides the fundamental framework for defining satellite communication frequency bands, their propagation characteristics, and the basis for selecting appropriate bands for VSAT applications.

2. ITU-R Recommendation P.618 β€” "Propagation effects relevant to satellite service"

Section Β§6 covers free-space path loss equations and frequency-dependent atmospheric effects. Section Β§7 addresses rain attenuation data essential for Ku/Ka-band VSAT link budgeting.

3. ITU-R Recommendation P.838 β€” "Propagation data for frequencies above 6 GHz"

Provides the specific attenuation model A_rain = k Γ— R^a with k and a coefficients for each frequency band used in the attenuation chart.
