Abstract:

A technique for attitude measurement of a nonrolling or slowly rolling vehicle in flight is described in this report. The technique employs a two-color, oscillating laser beam to sweep the flight vehicle. Light is retroreflected from on-board corner cubes to receivers colocated with the transmitter. The output consists of event times for the retroreflected pulses which may be used to infer pitch and yaw attitude. A mathematical model of the system is presented as well as a data reduction algorithm. Author
