Technical write-ups on HAPS link budgets, ITU-R propagation models, and non-terrestrial network engineering.

Methodology v0.9 draft

Validation Methodology & Reference Implementation

A six-tier validation pyramid for the HAPIS Link Budget API — code verification, ITU-R / 3GPP reference cases, cross-tool checks, empirical comparison, sensitivity analysis, and continuous integration. Explicit about which tiers are operational today and which are scheduled for v1.1 / v2.0.

ITU-R P.525 / P.676 / P.838 / P.840 / P.2108 3GPP TR 38.811 / 821 / 822 V&V 20 · NASA-STD-7009A · P.311
