Authors: Thomas E. Harkins and Michael J. Wilson
Date/Pages: September 2007; 20 pages
Abstract: A technique for obtaining pitch, yaw, and roll rates of a projectile from a single, low-cost, commercial off-the-shelf magnetometer has been developed at the Advanced Munitions Concepts Branch of the U.S. Army Research Laboratorys Weapons and Materials Research Directorate. In this report, the magnetometer-based methodology is presented, the flight experiment and subsequent analyses are described, criteria for use of this methodology are given, and the potential uses of this technique in inertial measurements unit/INS applications are discussed.
