HRL Laboratories has introduced a new inertial measurement unit (IMU) that provides near navigation-grade accuracy in a palm-sized package.
Smaller and lighter than grade-equivalent conventional sensors, HRL’s AXI-R100 delivers range-extending accuracy for GPS-contested navigation. The product is now ready for pre-production orders.
Using silicon microelectro-mechanical systems (MEMS) technology, HRL’s gyros exceeds the performance of many tactical-grade IMUs in the same or smaller package size, and is manufactured in high volumes at wafer-scale. This near navigation-grade performance is available at a tactical-grade price.
The new IMU is suitable for use in defense, aerospace and automotive applications, including missile-guidance systems and drone navigation, as well as for commercial automotive applications with higher levels of autonomy. The product is ready for integration as it has been designed and tested against challenging vibration, shock and thermal conditions representative of those applications.
HRL will present product specifications at the 2026 Joint Navigation Conference, taking place this week in Cincinnati, Ohio, and is exhibiting in booth 129.
By leveraging high volume design automotive methodologies, HRL designed AXI-R100 navigation sensors to scale for high-volume automotive demand while maintaining performance superiority over traditional tactical-grade sensors. The result is a gyroscope compatible with foundry fabrication processes for high volume applications.
“Our gyroscopes and inertial sensors support navigation, pointing and stabilization systems for autonomous vehicles, aircraft and guided missile and munition applications,” said Jeff Dickman, director, Precision Sensing, HRL Laboratories. “We leveraged our extensive microelectronics legacy along with innovations in micromechanical and manufacturing processes to pave the way for AXI-R100 to address the urgent needs from our industrial base.”
