- Аннотация: A low-frequency (up to 8 hours) drift characteristics of LTS and HTS SQUIDs were measured in DC-bias and AC-bias modes, as well as a long-term output signal behavior of registration system electronic components. Obtained results combined with a previously shown transfer function [3] allow to expect an observable low-frequency drift at rates 10-5 grad/hour and higher with an unoptimized system. This result corresponds well to current navigation systems based on non-superconductive gyroscopes [2]. Mathematical approaches to a low-frequency drift compensation were shown, as well as a real-time output voltage compensation method. Further adjustments of registration system electronic components could reduce a low-frequency drift even more.
