The LR-500 is a lightweight, low-power consumption, MEMS-based and vibration-isolated IMU that stands in a class by itself. It features Northrop Grumman’s proven solid-state silicon MEMS accelerometers and our MEMS QMG in a common IMU package. It delivers the durability and performance required for platform stabilization, guidance, and control in GPS-challenged applications — even operating in severe environmental conditions. Consistent with Northrop Grumman’s standard-setting LN-200 Fiber-optic Gyro (FOG) IMU, the LR- 500 provides inertial, sensor-based incremental velocity and incremental angle output data over a digital serial data bus for a wide variety of applications.

Integral to the LR-500, the QMG combines the best features of tuning forks and ring gyroscopes to maximize positioning, navigation and timing (PNT) capabilities. Northrop Grumman’s QMG silicon accelerometer (SiAc) sensors deliver performance levels similar to FOG- and Ring Laser Gyro-based (RLG) systems, while maintaining traditional benefits of MEMS sensors with regard to SWaP-C and reliability.

The LR-500’s premier capabilities make it the clear IMU of choice for a wide range of tactical to near-navigation grade applications, including:

• Electro-Optical (EO)/Forward-looking infrared (FLIR)/ camera – radar stabilization
• Missile guidance
• Flight control
• Oil and gas pipeline inspection
• Mining
