About

About excav

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.
