TACNAV 3D

A-PNT-capable, Highly Accurate Full 3D Navigation in All Terrains

The FOG-based TACNAV® 3D tactical inertial navigation system provides an assured position, navigation, and timing system with an embedded GNSS and optional Chip-scale Atomic Clock (CSAC). TACNAV 3D’s modular tactical design means it functions as a standalone inertial navigation solution, and as the core of an A-PNT-capable multi-functional battlefield management system. Features of the field-tested TACNAV 3D include:

  • KVH’s highest performing IMU for reliable 100% situational awareness even when GPS/GNSS is unavailable
  • Extremely accurate heading, dead reckoning navigation, and orientation at a lower cost than competing systems
  • 1 pulse per second (PPS) timing assurance during loss of GPS/GNSS

The TACNAV 3D is controlled by the Arms Export Control Act (Title 22, USC Sec 2751 et seq.) and the International Traffic in Arms Regulations, ITAR, 22 CFR 120-130, and may not be exported from the United States or disclosed to a foreign person in the United States except as authorized by those regulations.
