A compact, lightweight, cost effective, self-contained standby electronic
navigation system with high signal-to-noise ratio and good dynamic
stability is provided. The system includes a first sensor module for
providing a plurality of rotational rate signals, a second sensor module
for providing a plurality of compensation signals, and a microcontroller
module for processing the rotational rate signals and the compensation
signals and sending the signals to a display for displaying attitude
information, directional information, and turn coordinate information on a
single screen simultaneously. In one embodiment, the first sensor module
includes a plurality of rotational sensors made of piezoelectric elements.
The piezoelectric elements are made from a single sheet of piezoelectric
material so that the elements possess uniform characteristics, and are
arranged to reduce systematic drift and random noise normally present in a
rotational rate sensor. The sensors can be configured on a single
multi-sensor chip.
