excav develops portable 3D GNSS machine-guidance systems for earthmoving equipment. Its excav PILOT transfers between excavators, loaders, dozers and other machines without permanent wiring or vehicle modification.
About
Founded by Emanuel Sizmann and Florian Heiß in 2023, excav emerged from work with Friedrich-Alexander University Erlangen-Nuremberg and entered the ESA Business Incubation Centre Bavaria in 2024. Its early product was recognised by VDBUM and BayStartUP before the company converted from a German UG into excav GmbH in 2025.
The PILOT system uses one GNSS sensor mounted directly on the tool, a cab display and a tablet application. It imports PDF plans and terrain models, accepts RTK corrections over NTRIP and is marketed with relative accuracy of roughly ±15 mm under suitable correction conditions. A magnetic, cable-free installation and five-minute tool calibration distinguish it from permanently installed machine-control systems, making the same kit usable across mixed fleets. The operator remains in control; the platform is an assistance and positioning layer rather than full machine autonomy.
