Prototyping a basic MEMS attitude heading and reference system
2011 IEEE International Conference on Industrial Technology, 2011This article presents the creation of a basic platform for inertial measurements. It will be used in the development of an automatic pilot for the unmanned aerial vehicle (UAV) projects from Instituto Militar de Engenharia (IME). The platform consists not only of the hardware which contains the sensors capable of doing inertial measurements, but also ...

Design and implementation of an Attitude and Heading Reference System (AHRS)
2011 8th International Conference on Electrical Engineering, Computing Science and Automatic Control, 2011This paper deals with the development and implementation of a cheap Micro Attitude and Heading Reference System (AHRS) using low-cost inertial and magnetic sensors. The orientation is parameterized with unit quaternion and the data fusion is done unifying a quaternion linear formulation of Wahba's problem with a Multiplicative Extended Kalman Filter ...

An attitude heading and reference system: Basic concepts and prototype
2011 IEEE International Symposium on Industrial Electronics, 2011This article proposes a basic platform for inertial measurements. In order to control an autonomous vehicle, it is fundamentally important to know its attitude. For aerial vehicles, this information is critical to determining the control loop's feedback parameters.

Design and validation of an attitude and heading reference system for an aerial robot prototype
2012 American Control Conference (ACC), 2012In this paper we consider the design and the experimental validation of an attitude and heading reference system for a miniature aerial robot prototype based on measurements obtained from a low cost off-the-shelf inertial measurement unit. Different estimation algorithms to process the raw inertial data are implemented and validated in real indoor ...

Developing an Attitude and Heading Reference System based on Advanced MEMS Gyros
AIAA Infotech @ Aerospace, 2015Attitude measurement performance onboard aeronautical transport platforms is a key issue to enanche mission capabilities of current systems. Indeed, the standard attitude measurement accuracy FAA requirements, i.e. 1° rms for pitch and roll and 3° rms for heading, are intended for typical mission profiles that where adopted in the past.

Secure Estimation for Attitude and Heading Reference Systems Under Sparse Attacks
IEEE Sensors Journal, 2019This paper focuses on the problem of secure attitude estimation for autonomous vehicles. Based on the established AHRS measuring model and the attack model, we have decomposed the optimal Kalman estimate into a linear combination of local state estimates.

Invariant observer design of attitude and heading reference system
Control Theory and Technology, 2019An attitude and heading reference system (AHRS) is a nonlinear state estimator unit for computing orientation in 3D space. This paper designs an AHRS using three approaches: an invariant observer, an invariant extended Kalman filter (IEKF), and a conventional extended Kalman filter (EKF).
