Abstract: A flexure plate accelerometer system includes a flexure plate and two fixed plates on either side of the flexure plate. The flexure plate generates a flexure plate signal as a function of reference signals received in the fixed plates. A precision transformer generates the reference signals from a precision sine wave generated by a symbol generator controlled by a microprocessor. The microprocessor controls the symbol generator and activates an analog-to-digital converter in response to a signal coincident with a positive and negative peak of the precision sine wave. The analog-to-digital converter generates a digital word from the flexure plate signal, which is processed further in the microprocessor.

A processor receives the accelerometer signals and generates the platform control signal in response thereto.
