Inertial Navigation Systems (INS)
Discover cutting-edge solutions from 8 leading global suppliers
HBK has unveiled the 3DM-CV7-GNSS/INS, an ultra-compact, tactical-grade inertial navigation system designed for seamless integration into space-constrained platforms.
Combining advanced inertial technology with tightly coupled, onboard dual-frequency GNSS (Global Navigation Satellite System) receivers, the 3DM-CV7-GNSS/INS provides the accuracy and reliability required for navigation and localisation in dynamic environments, including those where GNSS signals may be weak, intermittent, or unavailable.
From autonomous robotics to drones and UGVs (unmanned ground vehicles), this new solution addresses a key engineering challenge, delivering consistent, high-quality data under difficult operating conditions.
Weighing 15.6 grams and measuring 38 x 30 x 10 mm, the 3DM-CV7-GNSS/INS offers tactical-grade performance in a compact, lightweight package. Its Adaptive Extended Kalman Filter, full industrial temperature calibration, and user-friendly interface support robust data acquisition across a range of real-world scenarios.
Engineers also benefit from the sensor’s compatibility with open-source platforms such as PX4 and ROS™, making it easier to integrate into existing systems and streamline development.
Justin Bessette, Engineering Manager at HBK, commented, “With the 3DM-CV7-GNSS/INS, we’re bringing tactical-grade performance to applications where every gram and millimetre matter. Built for real-world situations, this embeddable sensor is a flexible, ready-to-integrate solution – making advanced navigation easier to deploy and more dependable across the board.”
Low-latency data processing, accurate dead reckoning, and stable performance under demanding conditions allow the 3DM-CV7-GNSS/INS to improve the capabilities of embeddable navigation technology.
This innovation reflects HBK’s commitment to precise inertial sensing. With proven calibration standards, robust GNSS integration, and extensive configurability, HBK sensors continue to support demanding navigation and positioning requirements.
