Real Time Calibration of Strap-down Three-Axis-Magnetometer for Attitude Estimation
Three-axis-magnetometers (TAMs) are widely utilized as a key component of attitude determination subsystems and as such are considered the corner stone of navigation for low Earth orbiting (LEO) space systems. Precise geomagnetic-based navigation demands accurate calibration of the magnetometers. In this regard, a complete online calibration process of TAM is developed in the current research t...
متن کاملNovel Calibration Algorithm for a Three-Axis Strapdown Magnetometer
A complete error calibration model with 12 independent parameters is established by analyzing the three-axis magnetometer error mechanism. The said model conforms to an ellipsoid restriction, the parameters of the ellipsoid equation are estimated, and the ellipsoid coefficient matrix is derived. However, the calibration matrix cannot be determined completely, as there are fewer ellipsoid parame...
متن کاملThree - Axis Fiber Laser Magnetometer
Introduction: Acoustic detection of targets in shallow water environments is difficult due to high levels of anisotropic acoustic background noise. Detection range can be improved by simultaneously measuring nonacoustic signatures such as electromagnetic fields. A fiber laser vector magnetometer has been developed for seabed-mounted surveillance arrays. Three orthogonally mounted sensors measur...
متن کاملComplete Tri-Axis Magnetometer Calibration with a Gyro Auxiliary
Magnetometers combined with inertial sensors are widely used for orientation estimation, and calibrations are necessary to achieve high accuracy. This paper presents a complete tri-axis magnetometer calibration algorithm with a gyro auxiliary. The magnetic distortions and sensor errors, including the misalignment error between the magnetometer and assembled platform, are compensated after calib...
متن کاملMagnetic Calibration of Three-Axis Strapdown Magnetometers for Applications in Mems Attitude-Heading Reference Systems
In a strapdown magnetic compass, heading angle is estimated using the Earth's magnetic field measured by Three-Axis Magnetometers (TAM). However, due to several inevitable errors in the magnetic system, such as sensitivity errors, non-orthogonal and misalignment errors, hard iron and soft iron errors, measurement noises and local magnetic fields, there are large error between the magnetometers'...
