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).

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, 2016Many 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 ...

Survey on Attitude and Heading Reference Systems for Remotely Piloted Aircraft Systems
2014 International Conference on Unmanned Aircraft Systems (ICUAS), 2014Attitude estimation is a critical task for the safe navigation of RPAS (Remotely Piloted Aircraft System). When no 3D positioning information is available, e.g. due to GNSS (Global Navigation Satellite System) blockage, the autopilot must use data from the rest of the onboard navigation sensors to fly the RPAS in a stable manner and reduce potential ...

Optimization of Control Parameter for Filter Algorithms for Attitude and Heading Reference Systems
2018 IEEE Congress on Evolutionary Computation (CEC), 2018An Attitude and Heading Reference System (AHRS) provides orientation information of an object such as an Unmanned Air Vehicle by fusing sensor data from a magnetic and inertial measurement unit (MIMU). A MIMU consists of three components, which are a gyroscope, an accelerometer and a magnetometer.
