Yawsonde Technology for the Jet Propulsion Laboratory (JPL) Free Flying Magnetometer (FFM) Program
Abstract
The preliminary application of yawsonde technology to the Jet Propulsion Laboratory's (JPL) free flying magnetometer (FFM) program has been completed. An optical sensor design has been completed specifically to meet the volumetric constraints of the JPL FFM vehicle. Two sensor prototypes were fabricated, and one was extensively tested at the U.S. Army Research Laboratory. A review of yawsonde technology encompassing the optical sensors, installation within a flight vehicle, calibration, launch window simulation, flight testing, and data reduction is covered. The prospective sensor application is combined with projected solar ephemeris data and trajectory data to provide assurance of adequate coverage for projected flight tests. A data reduction methodology is developed wherein the sensors' orientation provides a means to determine solar aspect angle and solar roll rate of the vehicle.
