On the Viability of Magnetometer-Based Projectile Orientation Measurements

Abstract

Vector magnetometers are being widely considered for roll orientation estimation in a number of guided projectile programs. The U.S. Army Research Laboratory (ARL) has included vector magnetometers in inertial sensor suites in several hundred projectile test and evaluation flight experiments since the mid 1990s. Based on analyses and experiences with these devices, circumstances affecting magnetometer-based measurements have been identified and investigated. Results of these analytic and experimental efforts will be presented to support the conclusion that magnetometers are viable roll orientation sensors when properly employed.
