MK2M2: MEMS Tactical-Grade IMU, ITAR-Free / OSCP

MK2M2

The MK2M2 is an 11-DoF MEMS IMU in a 40 x 40 x 25 mm housing, 75 g, 1.2 W. Three-axis gyroscopes, three-axis accelerometers, three-axis magnetometer and two-axis inclinometers, output over RS-422 or CAN-FD at up to 500 Hz on 12 to 34 V.

Choose it when size, weight and power drive the design and GNSS is available most of the time: drone autopilots, ground robots, rail position systems and mobile mapping payloads. In-run bias stability is under 1.0 °/hr typical, 0.5 °/hr minimum, with 0.06 °/√hr angle random walk. On a 21 minute Montreal road test with GNSS position denied, the MK2M2 finished 20.5 m from truth.

Every unit is factory-calibrated for offset, scale factor and misalignment, plus magnetometer hard and soft iron. In the field you re-run gyro offset at startup and the magnetometer after each re-install.

Key features: Built for the field

Tactical-grade MEMS

Full MEMS inertial measurement with an angle random walk of 0.06 °/√hr, calibrated and compensated over the full operating range.

ITAR-free

Designed and built in Montreal, Canada. No ITAR content. Destination export screening still applies and we clear it before shipment.

Low SWaP

40 × 40 × 25 mm, 75 g, 1.2 W. RS-422 or CAN-FD at up to 500 Hz. The smallest unit in the family, for weight- and volume-constrained platforms.

Rugged & sealed

Tested to DO-160 style profiles at 2, 4 and 8 g vibration and 20 g and 40 g shock, Class A emissions, ESD at 4 kV touch and 8 kV air. IP67 certified.
