TACNAV® IIc Fiber Optic Inertial Navigation System

Low-Cost, Highly Accurate Fiber Optic Gyro-based Navigation for all Terrains – Featuring PIC Technology

The fiber optic gyro (FOG)-based TACNAV® IIc tactical Inertial Navigation System provides a solution with an embedded GNSS. Its modular tactical design and flexible architecture allow it to function as either a standalone tactical navigation solution, or as the core of an expandable, multi-functional Battlefield Management System (BMS).

TACNAV IIc joins the line-up of EMCORE’s inertial navigation systems and builds upon the success of the battle-proven EMCORE TACNAV family of products, and incorporates EMCORE’s high-performance, single-axis DSP-3000 FOG.

Ideal Navigation and Pointing Solution for the Digital Battlefield

Providing low-cost accurate heading and dead reckoning navigation and orientation, TACNAV IIc delivers 100% situational awareness in GNSS-denied environments with greater accuracy and at a lower cost than competing navigation systems.

  • Easily integrates with BMS to provides reliable vehicle position
  • Compact and lightweight
  • Designed for the close confines of turreted and non-turreted vehicles
  • The TACNAV IIc 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.
