MAGSONDE: A Device for Making Angular Measurements on Spinning Projectiles with Magnetic Sensors

摘要

Accurate measurement of angular motion of spinning bodies with on- board sensors has long been recognized as a daunting task. Recent advances in magnetic sensor technologies have yielded devices small enough, rugged enough, and sensitive enough to be useful in systems that make high-speed, high- resolution measurements of attitude relative to magnetic fields when these sensors are installed on free- flying bodies.
