HRL Laboratories Introduces Compact IMU With Near Navigation Grade Performance for Aerospace and Defense Systems

HRL Laboratories has unveiled the AXI R100, a palm sized inertial measurement unit engineered to deliver near navigation grade accuracy in environments where GPS access is limited or denied. For aerospace programs that depend on precise inertial sensing for guidance, stabilization and autonomous operations, the new unit represents a notable advancement in MEMS based navigation technology.

High Accuracy MEMS Sensing for Mission Critical Applications

The AXI R100 leverages silicon MEMS gyroscopes that exceed state of the art tactical grade performance while maintaining a compact form factor suitable for aircraft, uncrewed systems and guided munitions. HRL reports that the device has been tested against vibration, shock and thermal conditions representative of aerospace and defense environments, positioning it for integration into next generation navigation and pointing systems.

Designed for GPS Contested and Autonomous Operations

As aerospace platforms increasingly operate in GPS contested regions, inertial systems with higher accuracy and lower drift become essential. HRL’s new IMU is intended to extend operational range and maintain navigation continuity when external signals are degraded or unavailable. The company notes that the unit is ready for pre production orders, signaling a near term path to deployment for programs requiring resilient onboard navigation.

Scalable Manufacturing for High Volume Use Cases

HRL developed the AXI R100 using high volume automotive design methodologies, enabling wafer scale manufacturing that supports both defense and commercial demand. This approach allows the device to offer near navigation grade performance at a tactical grade price point, a combination that may appeal to aerospace integrators seeking to balance capability and cost across large fleets of autonomous or semi autonomous systems.

Continued Innovation in MEMS Navigation Technologies

The release highlights HRL’s two decades of research in MEMS inertial sensing, combining custom device design with advanced calibration and control algorithms. This long term investment has produced sensors capable of supporting precision navigation, pointing and stabilization across a wide range of aerospace applications. HRL will present technical details at the 2026 Joint Navigation Conference, underscoring the relevance of the technology to the broader navigation community.
