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-AR is a ruggedized IP68-rated tactical-grade Inertial Measurement Unit (IMU) and Vertical Reference Unit (VRU) manufactured by MicroStrain by HBK. The "AR" stands for "Attitude Reference," providing precise attitude measurements with relative yaw output without an integrated magnetometer, packaged in a water-resistant, dustproof IP68-rated enclosure for extreme environmental protection.

The 3DM-GV7-AR combines tactical-grade performance with IP68 environmental protection in a miniature ruggedized package. It features proven seventh-generation solid-state MEMS accelerometer and gyroscope technology, 1.5°/hour bias instability, Auto-Adaptive Extended Kalman Filter, and operates reliably from -40°C to +85°C. The IP68 rating ensures complete protection against dust ingress and water immersion, making it ideal for harsh outdoor and marine applications.

The IP68 rating means the 3DM-GV7-AR can operate in extremely harsh conditions including:

Complete dust protection: No dust ingress even in dusty industrial environments
Water immersion protection: Can withstand submersion in water
Outdoor environments: Weather-resistant for agricultural, construction, and field applications
Industrial settings: Protection from washdown procedures and contaminated environments

The key difference is environmental protection:

3DM-GV7-AR: IP68-rated ruggedized enclosure for maximum environmental protection, ideal for harsh outdoor, marine, and industrial applications
3DM-CV7-AR: OEM package (non-IP rated) optimized for size and weight in protected environments. Both share the same tactical-grade sensor technology and performance specifications.

The Auto-Adaptive Extended Kalman Filter is MicroStrain's advanced sensor fusion algorithm that automatically adjusts to changing environmental conditions and vehicle dynamics. In the IP68-protected 3DM-GV7-AR, it provides enhanced performance under highly dynamic conditions while incorporating automatic anomaly rejection for reliable operation in challenging environments.

The 3DM-GV7-AR includes advanced features specifically designed for challenging environments:

Custom Event Triggering System: Simplifies configuration and frees up CPU resources
Automatic Anomaly Rejection: Filters out environmental disturbances
Low Latency Processing: Reduces navigation errors from timing drift
External Clock Synchronization: Enables tight integration with LiDAR, cameras, and other sensors

Outdoor robotics: Agricultural equipment, construction machinery, field robots

Unmanned aerial vehicles (UAVs): Drones operating in adverse weather conditions

Unmanned ground vehicles (UGVs): Off-road autonomous vehicles and mobile robots

Industrial automation: Manufacturing equipment in harsh environments

Defense and tactical systems: Military vehicles and equipment in challenging conditions

Environmental monitoring: Weather stations, oceanographic instruments, remote sensors

Mining and construction: Equipment operating in dusty, wet, or contaminated environments

Absolutely. The 3DM-GV7-AR features adjustable sampling rates up to 1000 Hz, low-latency processing, and advanced filtering algorithms designed for high-dynamic applications. The IP68 protection ensures reliable operation in rain, snow, dust storms, and extreme weather conditions that would compromise non-protected sensors.

Yes, the 3DM-GV7-AR maintains the same compact footprint and precision mounting holes as the GX5 family, making it ideal for upgrading legacy platforms and new drone/robotics designs without mechanical redesign. This compatibility allows easy integration into existing systems while adding IP68 environmental protection.

Yes, MicroStrain provides factory-supported open-source, MIT-licensed ROS1 and ROS2 drivers specifically designed and tested for the 3DM-GV7-AR. These drivers enable seamless integration with robotics applications, unmanned vehicles, and simultaneous localization and mapping (SLAM) systems operating in harsh environments.

Yes, as part of the MicroStrain by HBK product line, the 3DM-GV7-AR meets compliance requirements for government and defense applications. The IP68-rated tactical-grade performance makes it particularly suitable for military and aerospace applications in demanding environmental conditions.

The ruggedized design of the 3DM-GV7-AR significantly reduces total cost of ownership by:

Eliminating sensor failures from environmental exposure
Reducing maintenance requirements in harsh conditions
Extending operational life in challenging environments
Minimizing downtime from moisture or contamination damage
Avoiding costly protective enclosures that would otherwise be required
