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.

Exclusive Technology
Precision Inertial Sensors
TACNAV systems feature KVH’s high-performance Fiber Optic Gyro (FOG)-based inertial sensors providing mission critical performance:
- Highly accurate gyros integrated with low noise accelerometers
- Three axes of magnetometers for automatic gyro bias compensation
- Very high bandwidth, low latency and low drift
Featured Options
Integrated Chip-scale Atomic Clock
The optional Chip-scale Atomic Clock (CSAC) timing option maintains PPS signal integrity during GPS/GNSS loss, a critical feature in preventing timing delays of PPS output to military radios, etc.
Iridium Two-way Messaging
An Iridium transceiver option is available to transmit and receive vehicle position, waypoint, and target location to or from a command center or other vehicles.
TACNAV Moving Map Display
The rugged TACNAV Moving Map Display (MMD) provides an easy-to-use graphical navigation capability for military vehicles by combining available internal or external GPS/GNSS with TACNAV’s inertial or compass-guided navigation solution.
TACNAV Universal Multilingual Display
KVH’s TACNAV Universal Multilingual Display (UMD) offers robust tactical display technology, capable of presenting navigation and other critical information in multiple languages.
