Abstract
The inertial rotation sensor comprising a vibrating resonator associated with transducers defining a pair of control channels and a pair of detection channels, preferably comprises a single multiplexer member for all of the channels, the multiplexer member being associated with a processing unit generating cycles comprising control action times on each control channel followed by detection action times on each detection channel, with two succession action times being separated by a relaxation time.
Claims5
An inertial rotation sensor comprising a vibrating resonator associated with transducers defining a pair of control channels and a pair of detection channels, the sensor including a multiplexer member for the pair of control channels and a multiplexer member for the pair of detection channels, and a single processing system associated with each multiplexer member,
- wherein the multiplexer member associates both pairs of channels with a single processing unit, and
- wherein the processing unit comprises a processing system having a control branch with an analog-to-digital converter and a detection branch with a very high gain corrector member associated with an analog-to-digital converter, and means for associating the control branch with the detection branch in a feedback loop.
