Abstract
Systems and methods are provided for determining the position of sensor elements in a sensor system. The sensor system includes a plurality of sensor elements. The platform comprises a plurality of MEMS IMUs, each associated with one of the sensor elements, measuring the acceleration and angular rate of the sensor elements. A controller determines the position and attitude of the sensor elements, based on the acceleration and angular rate measured by each of the MEMS IMUs.
