KVH Industries has broadened its portfolio of photonic integrated chip (PIC) technology inertial measurement units (IMUs) with the introduction of the P-1750 and P-1725 models. These latest additions, alongside the previously launched P-1775, are equipped with advanced accelerometers and a compact design, enhancing sensor performance and navigation capabilities while providing superior resistance to vibrations and shocks. These IMUs are particularly well-suited for demanding applications in unmanned aerial vehicles (UAVs) and autonomous systems.
Innovative Technology Behind KVH IMUs
The PIC technology utilized by KVH incorporates a planar optical chip that consolidates multiple fiber optic components,leading to streamlined manufacturing processes and enhanced reliability. The accelerometers integrated into the P-series IMUs deliver remarkable sensitivity and precision across their dynamic ranges, achieving substantially improved drift (bias instability) and noise (velocity random walk) performance compared to earlier models, and offering over ten times the accuracy of lower-cost MEMS inertial measurement units.
Versatile Applications and Integration
The P-series IMUs are designed for seamless integration, featuring adaptable power and dialogue interfaces, consistent unit-to-unit repeatability, and extended product lifespan due to the advantages of PIC technology. They are ideal for a diverse range of challenging environments, including land, maritime, and aerial applications, such as autonomous trucks, passenger transport systems, drones, autonomous underwater vehicles (AUVs), remotely operated vehicles (ROVs), and stabilization platforms.
Options for Enhanced Performance
The expanded P-series line offers various options for engineers in the autonomous sector seeking enhanced performance and a selection of low-noise, high-performance accelerometers. The P-1775 model stands out as KVH’s flagship IMU, providing top-tier accuracy with options for 10g or 30g accelerometers tailored to meet the specifications of autonomous platforms.The P-1750 model serves as a versatile high-performance IMU, also available with 10g or 30g accelerometers for both autonomous and manned applications. Simultaneously occurring, the P-1725 is a compact, commercially viable IMU featuring PIC technology and 10g accelerometers, offering excellent performance as a cost-effective alternative to lower-performing MEMS products.
Commitment to Innovation in Autonomous Technology
Martin Kits van Heyningen, CEO of KVH, stated: “We are excited to further incorporate our innovative PIC technology into our inertial navigation solutions, catering to the expanding autonomous market. KVH has been at the forefront of autonomous technology advancements for over 15 years, dating back to the 2005 DARPA Grand Challenge for self-driving vehicles, and continuing with the autonomous shuttles and trucks currently undergoing testing on public roads with our inertial products. Our PIC technology exemplifies our commitment to innovation.”
