FAS-G combines an angular rate gyro with two orthogonal DC accelerometers, 12 bit A/D converter, multiplexer, microcontroller, and D/A converter to provide an analog voltage linearly proportional to inclination in dynamic and static environments.
Operating over the full 360 degrees of angular motion, FAS-G is versatile by
design. The additional digital serial output can be programmed to provide either
compensated angles or raw sensor data. The digital output modes and software
filter parameters are user programmable. All programmed parameters are stored
in nonvolatile memory.
