Product Description

The MicroStrain 3DM-CV7-GNSS/INS 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.

 

Key features

GNSS

• High-rate GNSS input for improved low speed position accuracy
• Dual antenna heading for accurate heading measurements immune to magnetic disturbances
• RTK support for centimeter-level positioning accuracy
• NMEA input over GPIO simplifies external GNSS input using a single GPIO line

EKF

• INS with a flexible, adaptive EKF designed for demanding navigation applications
• 5 Reference Frame configurations for simplified external aiding sensor input
• External aiding input support for a wheel speed sensor, external GNSS, and more
• Multiple external aiding measurements accepted for improved GNSS-denied performance

Sensing

• User-adjustable sensor ranges (gyro and accelerometer)
• Fully temperature-compensated, tactical-grade IMU, mathematically-aligned to an orthogonal coordinate system

Features

• 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
• Pressure altimeter
• Dual RTK-capable GNSS receivers
