Built for ROS

Robot Operating System (ROS) is an open-source, meta-operating system for your robot. It provides the services you would expect from an operating system, including hardware abstraction, low-level device control, implementation of commonly-used functionality, message-passing between processes, and package management. ROS can be used in building and simulating robotics applications, as well as unmanned ground vehicles and simultaneous localization and mapping (SLAM). MicroStrain has an open source License free (MIT License) series of drivers specifically designed and tested for ROS.

The 3DM-GV7-INS is a tactical-grade ruggedized Inertial Navigation System (INS) that provides precise position, velocity, and attitude measurements. It features IP68 rating for harsh environments and accepts external position and velocity inputs to maintain robust navigation during GNSS outages.

The 3DM-GV7-INS combines tactical-grade performance with IP68 ruggedization in a miniature package. It features proven seventh-generation MEMS technology, advanced Extended Kalman Filter, flexible external aiding capabilities, and maintains the same compact footprint as the popular GX5 series for easy upgrades.

Absolutely. The IP68-rated precision-machined aluminum enclosure provides exceptional protection against water, dust, shock, and vibration. The tactical-grade performance and full temperature calibration ensure reliable operation in the most demanding industrial conditions.

The 3DM-GV7-INS features user-selectable accelerometer and gyroscope ranges to optimize performance for specific applications. The system is fully calibrated and temperature-compensated to maintain accuracy across all selectable ranges.

The 3DM-GV7-INS accepts multiple external aiding measurements including GNSS position and velocity data, external position sources, and industry-standard NMEA input over the AUX port. This flexibility improves GNSS-denied performance and maintains navigation accuracy during outages.

Yes, the 3DM-GV7-INS is defense-ready and accepts encrypted GNSS receivers, making it suitable for military and sensitive government applications where secure positioning is required.

NMEA (National Marine Electronics Association) input allows the 3DM-GV7-INS to receive standardized navigation data from external GNSS receivers and other positioning sources through the AUX port, providing flexibility in system integration and compatibility with existing hardware.

The 3DM-GV7-INS is ideal for:

Unmanned aerial vehicles (UAVs) and drones
Unmanned ground vehicles and mobile robots
Off-highway vehicle navigation
Marine autonomous systems
Industrial automation requiring precise positioning
Defense and military applications
Robotics requiring tactical-grade accuracy

The advanced Extended Kalman Filter (EKF) in the 3DM-GV7-INS provides sophisticated sensor fusion, combining inertial measurements with external aiding sources for optimal navigation accuracy. It automatically adapts to changing conditions and provides robust anomaly rejection for reliable performance.

The 3DM-GV7-INS features advanced time management and event triggering systems designed specifically for robotics and automation timing requirements. It supports adjustable sampling rates up to 1 kHz with precise timing synchronization capabilities.

Yes, MicroStrain provides open-source, MIT-licensed ROS drivers specifically designed for the GV7 series, including the 3DM-GV7-INS. Enhanced GNSS capabilities and ROS standards compliance are included in the latest driver versions.

Yes, the 3DM-GV7-INS includes an integrated magnetometer for absolute heading tracking. This provides magnetic heading reference when GNSS heading is unavailable, though the system can also operate with external heading sources.

The 3DM-GV7-INS is ruggedized with IP68 rating for harsh environments, while the 3DM-CV7-INS is optimized for size and weight in OEM applications. Both offer tactical-grade performance, but GV7 provides superior environmental protection and the CV7 offers the smallest package size.

Yes, as part of the MicroStrain by HBK product line, the 3DM-GV7-INS is NDAA compliant, making it suitable for U.S. government, defense, and critical infrastructure applications.
