The 3DM-GV7 offers tactical-grade inertial performance in a miniature, ruggedized package.
Ready for the harshest environments, the 3DM-GV7 features a precision-machined aluminum enclosure
and is tested to an IP68 rating.
The 3DM-GV7 includes a new feature set designed specifically for the demanding timing requirements
of the robotics and automation industries.
It is available in IMU/VRU (Vertical Reference Unit), IMU/AHRS (Attitude and Heading Reference System),
and INS (Inertial Navigation System) models.
