Technology Details

Exclusive Technology

Photonic Integrated Chip Technology
KVH’s new photonic integrated chip (PIC) technology* reimagines FOG technology by replacing individual fiber components with an innovative integrated planar optic chip. This results in a FOG with PIC Inside that’s even more reliable and delivers superior repeatability unit-to-unit. With three of these integrated photonic gyros at its core, the P-1775 IMU provides the safe, accurate performance autonomous platforms demand.

DSP Technology
KVH’s DSP electronics improve FOG performance in critical areas such as scale factor and bias vs. temperature, scale factor linearity, and maximum input rate. KVH’s exclusive DSP design overcomes the limitations of analog signal processing, eliminating temperature-sensitive drift and rotation errors.

Precision Testing

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
