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-GQ7-GNSS/INS is a tactical-grade Inertial Navigation System (INS) with integrated Global Navigation Satellite System (GNSS) capability. It combines dual multiband GNSS receivers with high-performance inertial sensors and Real-Time Kinematic (RTK) positioning to deliver centimeter-level position accuracy for autonomous navigation applications.

Real-Time Kinematic (RTK) is a satellite navigation technique that provides centimeter-level positioning accuracy by using correction data from a reference station. The 3DM-GQ7-GNSS/INS's native RTK capability enables precise positioning for applications requiring high accuracy like precision agriculture, surveying, and autonomous vehicle navigation.

SensorCloud RTK is HBK's multi-continent, IP-based RTK cloud network that delivers centimeter-level accuracy without complex base station setup. When paired with the 3DM-RTK Modem, it provides seamless, out-of-the-box RTK corrections across the U.S., Europe, and beyond with professional technical support.

Dual-antenna GNSS uses two separate antennas to determine heading direction with 0.25° accuracy that is immune to magnetic disturbances. This provides reliable heading information even in environments with magnetic interference, making it superior to magnetometer-based heading systems.

The 3DM-GQ7-GNSS/INS is ideal for:

Autonomous vehicle (AV) operation
Beyond Visual Line of Sight (BVLOS) drone navigation
Wheeled and legged robotics
Simultaneous Localization and Mapping (SLAM)
Precision agriculture and surveying
Marine autonomous systems
Industrial automation requiring precise positioning

Yes, the tactical-grade IMU with <2°/hr bias instability provides exceptional position accuracy during GNSS outages. The robust Auto-Adaptive Extended Kalman Filter maintains navigation capability when satellite signals are unavailable or degraded.

Absolutely. The system features adjustable sampling rates up to 1 kHz and advanced tightly-coupled Extended Kalman Filter designed for exceptional performance in dynamic conditions, making it ideal for fast-moving platforms and high-acceleration applications.

Yes, MicroStrain provides open-source, MIT-licensed ROS drivers specifically designed and tested for the 3DM-GQ7-GNSS/INS, enabling seamless integration with ROS-based robotics applications and autonomous systems.

The Auto-Adaptive Extended Kalman Filter is an advanced sensor fusion algorithm that automatically adjusts to changing environmental conditions and dynamics. It provides tightly-coupled integration of GNSS and inertial data, ensuring optimal performance and robust anomaly rejection in challenging conditions.

The system uses multi-constellation receivers with 184 tracking channels each for robust signal tracking, dual-antenna heading immune to magnetic interference, tactical-grade IMU performance, and advanced algorithms that provide exceptional dynamic performance and automatic anomaly rejection.

The 3DM-GQ7-GNSS/INS offers the highest accuracy tactical-grade performance in a compact 78-gram package, with native RTK capability, dual-antenna heading, and a complete single-vendor solution including cloud-based RTK corrections - features typically found only in much larger and more expensive systems.

Yes, as part of the MicroStrain by HBK product line, the 3DM-GQ7-GNSS/INS is NDAA compliant, making it suitable for U.S. government and defense applications.
