What it rests on

Every number here rests on one of six kinds of thing: a published price or datasheet, a measurement, a standard or regulation, a calculation from sourced figures, a design choice, or an assumption written down.

Standards and data

ITU-R P.526-15 §4.5.2, delta Bullington diffraction.
ITU-R P.452 and P.1812: how the signal weakens on its way.
3GPP TR 38.901 Table 7.4.1-1: shadowing widths.
Copernicus DEM 30 m: ground heights.
OpenStreetMap and Overture: buildings, and the masts, signs and boards along the road.
Semtech SX1280, EBYTE E28-2G4M20S and E28-2G4M12S, Qorvo DWM3000 datasheets, and the SX1280 long range test.
Tier prices from DigiKey, LCSC, JLCPCB, Mouser, Gainta and other sellers, 25 to 28 September 2026. Exchange rates of 4 September 2026, 48,44 TL a dollar and 1,1622 dollars a euro.
The rows of the comparison table that are not ours come from the bibliography below. Every note under the table links to the entry it rests on.

Bibliography

Every hyperlink in the report's bibliography, as the report wrote it, and the sources the site added for its cost and regulation figures. An entry no note cites is still listed.

Satellite and regional satellite systems

NavIC

Terrestrial systems

Reproducing the table

pip install -e ".[dev]"
yerkon table          # the published numbers, ~15 min
yerkon table --fast   # for trying things, ~1 min
yerkon view           # this site and the simulation

The terrain data ships inside the package, so the table reproduces with no network at all. The random seed is fixed, so every run gives the same answer.
CONTEXT.md is the glossary: the name the code uses for each term beside the one the report uses.
