FIELD: gyroscopes.
SUBSTANCE: invention is based on the phenomenon of nuclear magnetic resonance, namely to a means of simultaneous generation of a magnetic field and thermal stabilization of a quantum rotation sensor. The device contains a solenoid, gas cells (GC), a temperature sensor, transverse field receiving coils, a transverse field signal amplifier, a temperature sensor error signal amplifier, a controller for controlling temperature and Larmor precession frequency in transverse coils. Two DC sources are connected to the controller output, loaded on the windings of direct and reverse currents (i1, i2) of the solenoid to provide total and differential currents for stabilizing the temperature and magnetic field. As a result of processing input signals, controller 9 generates control signals at outputs 1 and 2 such that DC sources 10 and 11 generate currents i1 and i2, respectively, allowing in total (i1+i2) to heat cell 2 to temperature T0 with retention it at the level of accuracy required for a quantum system, and the difference current (i1-i2) to create and maintain a constant magnetic field Bz at the required level of accuracy.
EFFECT: getting rid of parasitic magnetism created by the heater and uncontrolled heating created by magnetic coils.
