Abstract : Formulas are derived which determine the aspect of a rocket, the angle of attack of the rocket axis with respect to the velocity vector or any other given vector, the aspect of any vector perpendicular to the rocket axis, and the angle of attack of such a vector with respect to the velocity vector or any other given vector, by means of telemetered magnetometer data alone. It is well known that the aspect of a well-behaved rocket can be determined from the history of its motion from the introduction of the first piece of data. The 'least squares' representation of the telemetered axial magnetometer data provides this history from any initial time tN after the motion of the rocket is well behaved. The orientation of the rocket axis eN at this initial time tN is provided by establishing the history of the spacecraft from the time of launch to tN. A method for determining this history is developed and the analysis used to reduce telemetered data from a specific flight to aspect of that rocket. (Author)
