Photonic Integrated Chip Drives High-Performance IMUs

KVH Industries launched the P-1750 inertial measurement unit (IMU) and the P-1725 IMU to enrich its beforehand launched P-1775 IMU and create a full line of IMUs that function high-performance accelerometers and KVH’s patented photonic built-in chip (PIC) know-how. The KVH P-series IMUs are supplied in the identical compact IMU housing. They supply dynamic and correct sensor efficiency, delivering improved navigation functionality and environmental robustness in vibration and shock functionality for difficult purposes, significantly the autonomous market.

The P-series IMUs are designed for probably the most difficult purposes on land, sea, and air, together with autonomous vans and folks movers, drones, AUVs, ROVs, and platform stabilization. The industries that leverage these purposes embody transportation, navy, agriculture, development, and mining.

“KVH has been energetic in autonomous know-how developments for greater than 15 years,” saidMartin Kits van Heyningen, KVH’s chief government officer, “going again to the 2005 DARPA Grand Challenge for self-driving automobiles as much as the autonomous shuttles and vans at present being examined on the highway with our inertial merchandise. Our PIC know-how is the most recent instance of our innovation.”

KVH’s PIC know-how options an built-in planar optical chip that replaces particular person fiber optic elements to simplify manufacturing and enhance reliability. The accelerometers used within the P-series IMUs supply larger sensitivity and accuracy of their dynamic ranges. This means KVH P-series IMUs are designed to ship an order of magnitude higher drift (bias instability) and noise (velocity random stroll) efficiency than prior merchandise and supply greater than 10 instances increased accuracy than inexpensive MEMS inertial measurement items. KVH P-series IMUs function simple integration with versatile energy and communications interfaces, excellent repeatability unit-to-unit, and elevated product life on account of the PIC know-how.

With the expanded line of P-series IMUs, KVH offers a number of choices for autonomous engineers who’re in search of improved efficiency and a alternative of low-noise, high-performance accelerometers at a good worth level.

  • The P-1775 IMU is KVH’s premier IMU when it comes to accuracy and is obtainable with 10g or 30g accelerometers to satisfy autonomous platform specs.
  • The P-1750 IMU is a flexible high-performance IMU that includes a alternative of 10g or 30g accelerometers for autonomous and manned platforms.
  • The P-1725 IMU is a compact, industrial IMU that includes PIC know-how and 10g accelerometers for excellent efficiency and serves as an inexpensive various to decrease performing MEMS merchandise.

KVH’s broadly fielded TACNAV tactical navigation techniques are at present in use by the U.S. Army and Marine Corps in addition to many allied militaries world wide. KVH’s fiber optic gyros (FOGs) and FOG-based IMUs are in use immediately in all kinds of purposes starting from optical, antenna, and sensor stabilization techniques to cellular mapping options and autonomous platforms and vehicles.
