Litton has constructed an Advanced Development Model (ADM) of an Integrated Inertial Sensor Assembly (IISA), on contract to the U.S. Naval Air Development Center. IISA is designed to provide all sensor needs for modern military aircraft, including flight control and navigation, with reduced avionics cost through the use of redundant skewed inertial navigation sensors. Various design aspects of using six ring-laser gyros and six inertial-grade accelerometers in two, separated clusters are described. The redundancy management mechanization and the system design features for maximum flight safety are given. Navigation performance limits of strapdown INS, including the effects of skewed sensors, are presented.
