MK2Z: Navigation-Grade Photonic IMU Prototype / OSCP

MK2Z

Prototype. Specifications are preliminary and subject to change.

OSCP’s MK2Z is a navigation-grade prototype IMU built for demanding applications including autonomous heavy machinery, precision agriculture, construction, aerospace, defense, UAVs, marine and subsurface navigation, and health monitoring of machinery. Featuring the navigation-grade prototype optical gyroscope on the Z axis alongside accelerometers, magnetometers and inclinometers, the MK2Z targets long-term heading stability and low drift in GNSS-denied conditions.
