Abstract
It is shown that a fibre optic gyro is influenced by external magnetic fields, yielding an increased bias instability with increasing field strength. In an experimental set-up a bias uncertainty of about 10 degrees/hour is obtained, if the earth magnetic field is acting upon the fibre coil. By protecting the fibre coil against external magnetic fields an improvement by at least one order of magnitude is obtained.
