Calibration of Strapdown Magnetometers in Magnetic Field Domain
TL;DR: In this paper, an iterated, batch least squares estimator is used to calibrate a magnetometer triad with a two-step nonlinear estimator. But the algorithm is limited to two-axis systems and the post-calibration residuals are small and result in a system with heading errors on the order of 1 to 2 degrees.
Journal ArticleDOI
Design of multi-sensor attitude determination systems
TL;DR: In this article, the design of inexpensive multi-sensor attitude determination systems is discussed, where fuse information from a triad of solid state rate gyros with an aiding system mechanized using GPS or magnetometers and accelerometers are developed.
Proceedings ArticleDOI
A gyro-free quaternion-based attitude determination system suitable for implementation using low cost sensors
TL;DR: In this paper, an attitude determination system based on two vector measurements of non-zero, non-colinear vectors is proposed. But the approach is not suitable for real-time vehicle navigation, guidance and control applications.

GNSS Applications and Methods
TL;DR: The GNSS Signal Acquisition and Tracking (GSAT) as mentioned in this paper is a GNSS signal acquisition and tracking system that combines GNSS with RF systems to estimate position, velocity and time estimation.
