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). Key features and benefits of the IFOS FOG include:
Unprecedented noise and bandwidth specifications
Digital FOG output at the modulation frequency (10s 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)
