KVH Introduces P-series IMUs with PIC Technology and New Accelerometers


KVH Industries, Inc., announced the P-1750 IMU and the P-1725 IMU to complement the previously released P-1775 IMU. This creates a full line of IMUs that feature high-performance accelerometers and KVH’s patented photonic integrated chip (PIC) technology. KVH offers its P-series IMUs in the same proven, compact IMU housing design and now with more dynamic and accurate sensor performance. The result brings improved navigation capability and more environmental robustness in vibration and shock capability for more challenging applications.

“We are pleased to continue integrating our groundbreaking PIC technology into our inertial navigation products for use in the large and growing autonomous market,” says Martin Kits van Heyningen, KVH’s CEO. “KVH has been active in autonomous technology developments for more than 15 years going back to the 2005 DARPA Grand Challenge for self-driving vehicles up to the autonomous shuttles and trucks currently being tested on the road with our inertial products. Our PIC technology is the latest example of our innovation.”


KVH’s PIC technology features an integrated planar optical chip, replacing individual fiber optic components to simplify production and increase reliability. The accelerometers used in the P-series IMUs offer greater sensitivity and accuracy in their dynamic ranges. This means KVH designed its P-series IMUs to deliver an order of magnitude better drift (bias instability) and noise (velocity random walk) performance than prior products and offer more than 10 times higher accuracy than less expensive MEMS inertial measurement units. KVH P-series IMUs feature easy integration, outstanding repeatability unit-to-unit, and increased product life as a result of the PIC technology.

Additionally, KVH designed the P-series IMUs for the most challenging applications, including autonomous trucks, drones, AUVs, ROVs, and platform stabilization. The industries that leverage these applications include transportation, military, agriculture, construction, and mining.

With the expanded line of P-series IMUs, KVH provides multiple options for autonomous engineers seeking improved performance and a choice of low-noise, high-performance accelerometers at a more favorable price point than comparable offerings. KVH offers its most accurate IMU, the P-1775, with 10g or 30g accelerometers for autonomous platform specifications. The versatile, high-performance P-1750 IMU features a choice of 10g or 30g accelerometers for autonomous and manned platforms. Finally, the P-1725 IMU is a compact, commercial IMU featuring PIC technology and 10g accelerometers for outstanding performance. It serves as an affordable alternative to lower performing MEMS products.
