An independent integrity layer for navigation, trajectory and autonomous decision systems.

5DVNS Technologies

Volumetric positioning state for subsurface, subsea and space. Works with GPS/GNSS and INS when the fix is valid. Holds an admissible corridor when the fix is degraded, weak, compromised, or gone.

Position is treated as a state within a bounded volume, with GPS, INS, and other sensors providing observations. 5DVNS evaluates whether the state remains within physical and operational constraints by tracking remaining margins, the binding constraint, and whether motion is stable, recovering, or approaching a boundary. This provides a forward indication of admissibility without simulating the physical field and can operate over GNSS, inertial, SLAM, or other probabilistic estimators. It runs offline and at the edge, requiring no continuous satellite or cloud connection.
