Analog-digital integrator with improved
characteristics for inertial navigation systems

Dembitskiy N.L.
Push-pull method of balanced integration provides highly accurate calculation of the integral function for long periods of time, discrete control the start and reset the integrator.The first property provides accurate values of the integral function for a considerable period of time without using a complicated error compensation circuits. The second property allows to split the process of integration into successive time intervals without quantization of the input signal. Application error compensation of integration does not require adjustment integrators, additional procedures and schemes for the measurement of spurious integration, allows you to fully compensate for the effect of shear stress and displacement currentsat a time interval of integration. On the basis of the proposed method can build the control unit of the continuous integration in which the integration intervals are regulated supply timing pulses. In such devices simplified error compensation, no strict requirements on the stability of clock, it is possible to embed the generators into circuits of integrators. These features create the preconditions for the development of solid-state continuous-integration integrators for inertial navigation systems.
Key words: integrators, inertial navigation systems, analog signals.
