Analysis of a Reference System for a Mobile Laboratory.
Abstract
An inertial reference system has been designed for the Mobile Evaluation Laboratory using a KT-70 Inertial Measurement Unit, a speed sensor, a device for providing position data and two digital computers. The analysis needed to optimally combine the outputs of these equipments in the computer(s) has been accomplished. This analysis produced a twelve state recursive Kalman filter based on an error-state-space problem formulation. The Kalman error estimates are fed back to the INS to correct it. Means for handling the high data rate from the speed sensor have been analyzed and a computationally simple one has been chosen. The entire problem has been formulated in a computer simulation that was used in designing the system and predicting its performance. The final design will provide stable and accurate performance over a wide range of measurement conditions.
