P-1725 IMU

Affordable, Reliable FOG-based IMU with Photonic Integrated Chip (PIC) Technology

The new KVH P-1725 IMU is a rugged, non-ITAR IMU featuring breakthrough PIC technology for increased reliability and upgraded 10g or 16g high-performance accelerometers for outstanding FOG performance as affordable as MEMS alternatives. The P-1725 IMU is a 6-degrees-of-freedom (6-DOF) sensor that delivers the high performance and stability of KVH’s FOGs at MEMS prices.

This commercial-off-the-shelf, low cost/high performance photonic FOG-based IMU is ideal for applications in which affordability, high performance, and high bandwidth are critical.

  • Compact package weighing less than 0.7 kg (1.45 lbs) designed for ease of integration
  • Flexible interfaces, programmable message outputs
  • Versatile for unmanned platforms, precision stabilization systems, and high accuracy mobile mapping

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.

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
