Prototyping a basic MEMS attitude heading and reference system

2011 IEEE International Conference on Industrial Technology, 2011
This 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 ...

Human movement detection using attitude and heading reference system

Proceedings of the 7th International Conference on PErvasive Technologies Related to Assistive Environments, 2014
Among different types of human movement, falls are the most important since they related with high social and economic costs. Falls can cause various unintentional injuries such as fractures or in the worst-case scenario even lead to death, elderly citizen.

An Attitude Heading and Reference System for Marine Satellite Tracking Antenna

IEEE Transactions on Industrial Electronics, 2017
One of the most challenging problems for marine satellite tracking antennas (MSTAs) is to estimate the antenna attitude, which is affected by the ship motion, especially the ship vibration and rotational motions caused by ocean waves. To overcome this problem, an attitude heading and reference system (AHRS) for MSTA is presented in this paper ...

GNSS-Based Dual-Antenna Heading Augmentation for Attitude and Heading Reference Systems

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2016
Many current high-end avionics installations utilize redundant Inertial Navigation Systems (INS) with very high quality Inertial Measurement Units (IMUs) in order to maintain high accuracy heading with integrity. Attitude and Heading Reference Systems (AHRSs) that provide less accurate heading are frequently used on smaller business and regional ...

An attitude heading and reference system: Basic concepts and prototype

2011 IEEE International Symposium on Industrial Electronics, 2011
This 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.

Low-cost Attitude and Heading Reference System: Filter design and experimental evaluation

2010 IEEE International Conference on Robotics and Automation, 2010
This paper presents the design and performance evaluation of a low-cost Attitude and Heading Reference System (AHRS) for autonomous vehicles. A single sensor pack, an Inertial Measurement Unit (IMU), provides all the data required to feed the attitude filter.

Invariant observer design of attitude and heading reference system

Control Theory and Technology, 2019
An 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).

An Estimator for Attitude and Heading Reference Systems Based on Virtual Horizontal Reference

2016 American Control Conference (ACC), 2016
The output of the attitude determination systems suffers from large errors in case of accelerometer malfunctions. In this paper, an attitude estimator, based on Virtual Horizontal Reference (VHR), is designed for an Attitude Heading and Reference System (AHRS) to cope with this problem.

Developing an Attitude and Heading Reference System based on Advanced MEMS Gyros

AIAA Infotech @ Aerospace, 2015
Attitude 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.
