Inertial Sensors are Critical for Precise Autonomous Vehicle Navigation

  • GPS signals can be blocked by buildings, terrain, tunnels, parking garages, and signage, or intentionally jammed or spoofed.

  • Self-contained Fiber Optic Gyro (FOG)-based inertial sensors deliver situational awareness even when GPS is unavailable or jammed.

  • KVH inertial sensors are spoof-proof and jam-proof because they use integrated gyros and accelerometers, not external signals.

MEMS Fall Short Delivering Precision for Safe Autonomous Navigation

MEMS’ utilization of vibrating sensor technology (Coriolis effect) to measure rotation has inherent shortcomings:

  • Produces gyro noise, poor bias stability and low bandwidth that results in inability to achieve the centimeter-level precision required for safe autonomous vehicle navigation and positioning.

  • Susceptibility to environmental conditions (vibration, shock, temperature) leads to failures in moving vehicles where vibration and shock are common.

Groundbreaking Photonic Gyro Designed to Offer FOG Precision Competitive with MEMS Prices

  • KVH’s new groundbreaking Photonic Gyro is designed to provide spatial orientation data enabling geolocation at centimeter-level accuracy.

  • KVH’s Photonic Gyro technology is expected to rewrite the performance/cost equation to deliver mass-produced FOG-based precision and reliability at MEMS prices.
