- Delivers the critical precision navigational support that autonomous vehicles require
Inertial Sensors are Critical
GPS signals can be blocked by buildings, terrain, tunnels, parking garages, and signage, or intentionally jammed. Self-contained FOG-based inertial sensors deliver situational awareness even when GPS is unavailable or jammed.
MEMS Fall Short
MEMS’ utilization of vibrating sensor technology (Coriolis effect) to measure rotation has inherent shortcomings including noise, poor bias stability, low bandwidth, and susceptibility to environment conditions.
KVH Inertial Technology Provides Safe, Precise Autonomous Navigation
KVH inertial sensors are spoof-proof and jam-proof because they use integrated gyros and accelerometers, not external signals.

Photonic Chip Technology-based Inertial Systems
Disruptive Technology for Safe, Precise Autonomous Navigation
Fiber optic gyroscope (FOG)-based inertial navigation systems (INS) are key components of the inertial sensor systems essential for highly accurate autonomous vehicle performance. The accuracy and reliability of FOG-based inertial systems for autonomous vehicle navigation and safety has been well-established over millions of miles of testing in hundreds of prototype vehicles. However, the complex manufacturing process of these highly sophisticated systems has been a cost challenge for the mass production of these sensors for autonomous vehicles. Until now.Read the e-Book
