HRL Laboratories has introduced a new inertial measurement unit (IMU) designed to provide high-accuracy navigation in a palm-sized package. The AXI-R100 is intended for use in GPS-contested environments where traditional satellite signals are unavailable or unreliable.

The unit utilises silicon micro-electro-mechanical systems (MEMS) technology to achieve performance levels that exceed current tactical-grade sensors. The device is manufactured at wafer-scale, allowing for high-volume production suitable for the automotive, aerospace, and defence industries. It is specifically designed to withstand significant vibration, shock, and thermal stress.

The sensor is targeted at autonomous vehicle navigation and drone systems. By using automotive design methodologies, HRL aims to scale production to meet high-volume demand while maintaining the precision required for advanced autonomy.

“Our gyroscopes and inertial sensors support navigation, pointing and stabilisation systems for autonomous vehicles, aircraft and guided missile and munition applications,” said Jeff Dickman, Director of Precision Sensing at HRL Laboratories.

The company, which has spent 20 years developing MEMS sensing technology, is presenting the product specifications at the Joint Navigation Conference in Cincinnati, Ohio. Pre-production orders for the AXI-R100 are now being accepted.
