EMCORE Corporation is a leading designer and manufacturer of the world’s highest-performance Fiber Optic Gyro (FOG) and MEMS-based inertial sensors and navigation systems for aerospace and defense. Our comprehensive product suite serves a broad range of tactical, navigation- and strategic-grade requirements for armed forces worldwide, and are integrated into demanding defense platforms in the harshest conditions on land, sea, air and space.

Backed by decades of experience in inertial technology and assured positioning, navigation and timing (A-PNT), EMCORE’s combat-proven products for the battlefield deliver mission-critical information to warfighters and their equipment, ensuring success in precision military operations.

Tactical Navigation Solutions

Our TACNAV tactical navigation systems for military ground vehicles provide resilient and unjammable A-PNT capabilities without reliance on vulnerable satellite-based data. To date, EMCORE has manufactured and installed over 22,000 TACNAV systems on combat, command, and support vehicles of all types.

TACNAV Light/GPS
Light military vehicle navigation system with embedded GPS

TACNAV UMD
Universal multilingual display for military vehicle navigation systems

TACNAV TLS
Easy-to-integrate tactical navigation for turreted vehicles

FOG & MEMS IMUs

We offer FOG- and MEMS-based IMUs in a variety of performance variants to suit a range of military and defense requirements, up to navigation-grade. Our robust inertial measurement units provide reliable acceleration and angular rate outputs for GPS-denied navigation, precise targeting, line-of-sight stabilization and other mission-critical use cases.

TAC-450 Series
Tactical-grade IMUs with photonic chip technology

SDI500
Tactical-grade quartz MEMS IMU for rugged military environments

SDI170
