Surf6 works by mapping firelight  directly

Light Direction Detection 2 (LDD2) uses the shadow effect and specular reflection to map a fire’s origin.

Light Quality Detection (LQD) uses proprietary technique to map fire size and shape.

High sampling rate detects Flicker.

Surf6 is a modern use of Celestial Navigation:

Light direction is described as two angles from a plane. Our LDD2 reports a 3D bearing to a light source.
