Ensuring Performance through Rigorous Testing & Qualification


KVH engineer performing tests on the photonic chip

We rigorously test our new PIC technology to ensure superior performance, accuracy, and reliability.

  • Part Level – Testing includes over temperature cycling, temperature and humidity, and shock and vibration, all run over multiple lots of parts to validate the repeatability and robustness of manufacturing
  • Product Level – Testing is done across the complete set of performance specifications and environmental conditions and repeated over time to validate the design

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.

 

Why did May Mobility Partner with KVH?

Hear from Andrew Dykman, Senior Field Autonomy Engineer

"The KVH IMU on our vehicle gives us detailed, accurate and low noise information about how we’re moving through the world. This allows us to align ourselves and other things in the environment such as pedestrians, cyclists and other cars."
