Product Description

The MicroStrain 3DM-GV7 is a tactical-grade Inertial Navigation System (INS) in a miniature package. The flexible EKF can accept external aiding measurements to maintain a robust navigation solution during GNSS outages and touts a feature set designed specifically for the timing requirements of the robotics and autonomous vehicle industries. It is tested to an IP68 rating.

 

Key features

• IP68-rated enclosure
• An adaptive Estimation Filter (EKF) for sensor fusion
• Tactical-grade gyro
• User-adjustable sensor ranges (gyro and accelerometer)
• Integrated magnetometer for accurate heading tracking (AHRS only)
• INS with a flexible, adaptive EKF designed for demanding navigation applications
• Fully temperature-compensated, tactical-grade IMU, mathematically-aligned to an orthogonal coordinate system
• Multiple external aiding measurements accepted for improved GNSS-denied performance
• 5 Reference Frame configurations for simplified external aiding sensor input
• NMEA input over GPIO simplifies external GNSS input using a single GPIO line
• High-rate GNSS input for improved low speed position accuracy
• PPS input/output and external clock synchronization for precision time alignment with external devices
• Event triggering system and low latency data

 

Internal sensors

• 3-axis accelerometer
• 3-axis gyroscope
• 3-axis magnetometer (AHRS and INS only)
• Pressure altimeter (AHRS and INS only)
