Prony Analysis of Flat-Spin Motion from Accelerometer Data

摘要

The data from a flat-spin maneuver by a small spacecraft are used to investigate the performance of a motion measurement system constructed with nine linear accelerometers. A novel solution method yields only two values of the angular rate vector of the instrument, and subsequently the values for the linear and angular accelerations. The component values are approximated by complex exponential functions according to Prony's method.
