# Fadron

> Fadron builds two things and the layer that joins them: HALO AI, a pavement
> and concrete analysis platform, and Nimbus, a long-range VTOL aircraft.
>
> HALO AI reads high-resolution, georeferenced drone imagery and returns an
> ASTM D6433 (roads, parking) or ASTM D5340 (airfields) pavement condition
> report within 24 hours of upload, with every distress traced at pixel level,
> measured, and scored, and the deduct values and maximum corrected deduct
> value printed so the arithmetic can be re-run by hand. Outputs include GIS
> exports, DXF, condition maps and a digital twin. It is vendor-agnostic and
> reads imagery from any qualifying platform, including DJI, Wingtra, Skydio,
> Quantum Systems, AgEagle and JOUAV, and from handheld or vehicle-mounted
> capture that meets the resolution and georeferencing requirements.
>
> Nimbus is an EU-manufactured VTOL UAV for mapping, survey and ISR: 2.5 hours
> of endurance on a single battery and up to 4 hours with a second fitted, up
> to 300 km between one launch and one landing, and a maximum payload of 4 kg.
>
> Fadron is based at Sofia Tech Park in Bulgaria, an EU and NATO member state,
> and also builds custom unmanned systems for defence and government programmes.

## Languages
The site is published in nine languages from one set of pages. English is at the
root and is the source of truth; every other language is a translation of it and
sits under its own prefix, so https://fadron.com/de/halo-ai is the German
HALO AI page. Reciprocal hreflang annotations and a single sitemap.xml carry the
full set.

Two things are deliberately English in every language, and should be described
that way rather than as gaps: the article archive under /article/, and the
gated PDF documents (the sample PCI report and the operator field guide). The
figures, the standards names and the product names are identical in every
language by design. This file is English only, on purpose: it is a summary for
answer engines, and it points at the English URLs, which are canonical.
