The gIMU®-H is ultra miniature tactical grade Inertial Measurement Unit based on most advanced commercially available MEMS-Based sensors.
The gIMU®-H contains Hi-Performance best-in-class tactical sensors (3-axis Accelerometers, 3-axis Gyros) and can replace FOG-based systems providing superior C-SWaP features and improve system robustness, size, power-consumption and cost.
The gIMU®-H provides some advanced features making it suitable for different environments; the very-low VRE (< 100 µg/g2) making it ideal for dynamic, hi-vibration arenas, the rugged design allow it to face extreme environments, the dual supply voltage options (5 VDC & 9-32VDC) and various communication physical interfaces (RS422/RS232) and protocols (serial, SDLC) provides flexibility to accommodate to different tasks and more.
The gIMU®-H is factory-calibrated over Temperature, Bias, Scale-Factor, Cross-Axis & Mis-Alignment and g-Sensitivity.
