A multisensor of the vibrating- mass type comprises accelerometers (10, 12) mounted in parallel beam suspensions with their input axes (22, 24) substantially colinear. Forces are applied to the accelerometers through piezoelectric elements mounted to the suspensions to induce vibration so that coriolis rate information is included in the output of the system. Output circuitry discriminates between rate and linear acceleration information so that enhanced sensitivity to each parameter is obtained without confusion between coriolis and linear acceleration forces even when the frequency of linear acceleration is close to the modulation vibration frequency. Rate of rotation is sensed about axis (82). <IMAGE> |
