  1. Self-noise levels are given for a frequency range from 0.01 to 100 Hz. The levels are reported for a single vertical component giant FOG FARO from Streckeisen, Switzerland, a blueSeis-3A from iXblue, France, a single component FOG FOSREM from Elproma Elektronika, Poland, and two navigation-grade fiber-optic gyros as parts of 6DoF North-seeking gyros (PHINS and IMU50 from iXblue, France)
