Abstract
The invention is a method for reading out a vibratory rotation sensor comprising the steps of (1) driving the vibratory rotation sensor with a plurality of driving signals and (2) obtaining one or more readout signals resulting from the interaction of the driving signals and the vibratory rotation sensor. The functional dependence of all tracking-angle-dependent driving signals is expressible for a specified range of tracking-angle values as a single specific function of the tracking angle. A tracking-angle-dependent driving signal is the sum of two or more component signals where only one of the component signals is dependent on tracking angle. The single specific function specified for any one of a plurality of tracking-angle range of values can be the same as or different than the single specific function specified for any other tracking-angle range of values. In the preferred embodiment of the invention, the single specific function is the tangent of twice the tracking angle for certain tracking-angle ranges of values and is the cotangent of twice the tracking angle for other tracking-angle ranges of values. The readout signal has a functional dependence on both the tracking an…
