MicroStrain by HBK 3DM-CV7 Tactical Grade Ruggedized IMUs
MicroStrain by HBK 3DM-CV7 Tactical Grade Ruggedized Inertial Measurement Units (IMUs) offers tactical-grade inertial performance in the small and light OEM package. Each 3DM-CV7 is individually calibrated and features an Adaptive Extended Kalman Filter for optimal performance over various operating conditions. All 3DM-CV7 devices feature cutting-edge orientation algorithms, advanced internal time management, and a flexible event-triggering system. The INS model adds external position, velocity, heading inputs, and NMEA compatibility. With an unparalleled array of advanced features, the MicroStrain 3DM-CV7 sets its category's benchmark for value and performance.
