HEKA DRIMU
A high-precision navigation system that operates without GPS, using sensor fusion to continuously calculate position, velocity, and orientation.
6-DOF Inertial Sensing
Tracks motion in all directions for precise navigation and stability in dynamic environments.
Real-Time Processing & Resilience
Provides near-instant updates with minimal latency, operating reliably in extreme conditions.
Multi-Sensor Fusion
Combines accelerometers, gyroscopes, magnetometers, and barometers for reliable data and enhanced navigation.
GPS-Denied Navigation
Enables accurate positioning in GPS-denied environments like tunnels, urban areas, and underwater.
Compact Design
Lightweight and optimized for UAVs, UGVs, and space-constrained platforms without compromising performance.
AI/ML Kalman Filtering
Enhances Kalman filtering with AI and machine learning to minimize drift and sensor noise, ensuring long-term accuracy.
Real-Time Processing & Resilience
Provides near-instant updates with minimal latency, operating reliably in extreme conditions.
HEKA’s Nautilus Dead Reckoning IMU
HEKA’s Dead Reckoning Inertial Measurement Unit (DRIMU) is a 6-axis, waterproof (IP 67), 8 oz, compact design (1 in x 1 in x 1.5 in) and utilizes micro-electro-mechanical (MEMS) and micro-hemispherical resonating gyro (HRG) technology coupled with an advanced multi-source GNSS sensor. HEKA’s IMU is equipped with AI/ML error correction to allow for longer periods of accurate navigation in GPS-denied environments.
The DRIMU combines the best of both IMU and INS solutions. HEKA’s DRIMU drift is less than 0.1 mm/hr in these GPS-denied environments. It offers 12 hours of operation on a single charge, 50 mAh rechargeable lithium-ion battery, and USB-C power and data ports.
