Title 2

Vertical Reference Unit (VRU)

Product Status



The 3DM®-CX5-15 is the smallest and lightest industrial attitude reference available. It features a fully calibrated and temperature compensated triaxial accelerometer and gyroscope to achieve the optimum combination of measurement qualities under all dynamic conditions. The 3DM-CX5-15 is ideally suited for a wide range of applications, including platform stabilization antenna pointing and usage monitoring.

The CX product line has all the same features of the GX series in a cost-effective, system-integrator friendly package designed for volume production.

Features & Benefits

Best in Class Performance

  • Fully calibrated, temperature-compensated, and mathematically-aligned to an orthogonal coordinate system for highly accurate outputs
