The IFOS Fiber Optic Gyroscope (FOG) is a small ruggedized angular rate sensor suited to demanding applications in harsh environments in several variants, such as units for measurement while drilling (MWD) and robotics. Key features and benefits of the IFOS FOG include:
•Unprecedented noise and bandwidth specifications
•Digital FOG output at the modulation frequency (10’s of kHz) in the rotational rate domain
•No signature of angle quantization in Allan variance (-1 slope)
•No lower limit on AWN in frequency domain – PSD is ARW limited only
•Ultra-low:
•Angular jitter
•Angle White Noise (AWN)
•Angle Random Walk (ARW)
