Attitude and Heading Reference Systems (AHRS)
Discover cutting-edge solutions from 12 leading global suppliersMicroStrain by HBK has launched the new GV7 range of tactical-grade inertial sensors, offering a wide range of performance enhancements for demanding UAV (unmanned aerial vehicle), UGV (unmanned ground vehicle) and robotics applications.
The GV7 series represents a significant advancement over the preceding GX5 series, and currently includes three options – a tilt sensor/VRU (vertical reference unit), an AHRS (attitude and heading reference system), and an INS (inertial navigation system).
The GV7 range continues to offer leading SWaP (size, weight and power)-optimized design, and shares the same footprint and precision mounting holes as the GX5 family for easy and efficient drop-in replacement. All GV7 sensors now feature a rugged IP68-rated enclosure, enabling them to withstand harsh operating conditions in a variety of environments.
These new inertial sensors deliver a more accurate, reliable, and efficient solution, and almost every performance metric has been upgraded. The table below summarizes the improvements over the GX5 series:
| Specification | 3DM-GV7 | 3DM-GX5 |
| Environmental Protection | IP68 | Not rated |
| MTBF 2 | 058,917 hours 557 | 280 hours |
| Kalman Filter | 7th Generation Auto-Adaptive Extended Kalman Filter | 5th Generation Extended Kalman Filter |
| Output Data Rate (IMU and EKF) | 1 to 1000 Hz | 1 to 500 Hz |
| Accelerometer Range | User-adjustable: ± 4g, 8g, 16g | Fixed |
| Gyroscope Range | User-adjustable: ± 250 °/s, 500 °/s, 1000 °/s | Fixed |
