This paper presents an algorithm for calibrating strapdown magnetometers in the magnetic field domain. In contrast to the traditional method of compass swinging, which computes a series of heading correction parameters and, thus, is limited to use with two-axis systems, this algorithm estimates magnetometer output errors directly. Therefore, this new algorithm can be used to calibrate a full th...

An Expectation-Maximization approach to sensor calibration is presented and applied to three-axis-magnetometer calibration. This approach is different from the existing attitude-independent approaches mainly in how the attitude parameters in the attitude sensor measurement model are handled. The attitude-independent approaches rely on a conversion of the body and reference representations of th...

A small vector magnetometer has been constructed for DTUsat – a Danish CubeSat student project at the Technical University of Denmark. The presented magnetometer is used for attitude determination in conjunction with sun sensors, and supply local field measurements for the magnetotorquer controller. Present launch date is June 30th, 2003 from Plesetsk, Russia. Constraints on mechanical size, ma...

In-flight calibration of the spin axis offset of a fluxgate magnetometer with an electron drift instrument View the table of contents for this issue, or go to the journal homepage for more Abstract We show that the spin axis offset of a fluxgate magnetometer can be calibrated with an electron drift instrument (EDI) and that the required input time in...

Human body movement can be monitored through a wireless network composed of inertial sensors. This work presents the development of Wagyromag (Wireless Accelerometer, GYROscope and MAGnetometer), a wireless Inertial Measurement Unit (IMU) composed of a triaxial accelerometer, gyroscope and magnetometer. Communication is based on a 802.15.4 network. Furthermore, calibration, signal conditioning ...
