Abstract

The characteristics of a SQUID magnetometer-based readout system for a superconducting gyroscope-based inertial navigation system (INS) are investigated. The transformation function of the rotation angle of the gyroscope simulator to the voltage at the magnetometer output with a value close to 6.5 mV/deg is calculated and measured. This value corresponds to 4.1 V/deg for a superconducting gyroscope with a rotor diameter of 30 mm. Zero voltage drifts with a duration of up to 8 h are measured on the SQUID magnetometer. A drift of \(10^{-6}\) deg/h was detected.
