3DM-GV7-AHRS – Compact navigation system with AHRS

Ruggedized IP68 tactical grade IMU/AHRS. Individually calibrated for optimum performance. Features an advanced Extended Kalman Filter, cutting-edge orientation algorithms, advanced time management, and event triggering system.

Sensor

• Tactical Grade Gyro (1.5°/hr bias instability) - Improved position accuracy during dead reckoning
• Fully calibrated over entire temperature range
• Roll/pitch accuracy: Static: 0.25°; Dynamic: 0.5°
• Heading accuracy: Static: 0.5°; Dynamic: 2.0°
• Integrated magnetometer for absolute heading tracking
• Auto-Adaptive Extended Kalman Filter (EKF) for Orientation Estimation
• Low Latency - Reduces navigation errors from clock drift when combining with external aiding sensors
• Adjustable Sampling Rates - Faster response to vehicle dynamics
• Custom Event Trigger System - Simplifies configuration of context-based events and frees up CPU on vehicle main board
• External Clock Synchronization - Tighter synchronization with external sensors like LiDAR or cameras to improve state estimation
• I/O: Two low-latency GPIOs for Events, Alarms and PPS I/O
• RS232 and USB interface
• Output: MIP and NMEA protocols
