A Non-Linear,Two-Step Estimation Algorithm For Calibrating Solid-State Strapdown Magnetometers
Magnetometer Heading Non-Linear Estimation
2015/6/29
This paper presents a new algorithm for calibrating modern, solid-state strapdown magnetometers. The traditional method for cali brating these sensors is a cumbersome procedure called “swinging” which...
