An estimator for Attitude and Heading Reference Systems based on Virtual Horizontal Reference
2016 American Control Conference (ACC), 2016The 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.

Development of attitude and heading reference systems
2015 International Automatic Control Conference (CACS), 2015The development of an attitude and heading reference system (AHRS) using sensor fusion is presented in this paper. The system consists of a nine degree of freedom inertial measurement unit (IMU) and a digital signal processor (DSP) module. The IMU comprises with triaxial gyroscopes, triaxial accelerometers, and triaxial magnetometers.

Dynamic attitude estimator for attitude and heading reference systems based on vector observations
2016 IEEE International Conference on Information and Automation (ICIA), 2016A novel attitude estimator for applications under dynamic conditions is proposed in this paper, which is based on the vector observations of gravity, geomagnetic field, and angular velocity. After a brief review of the existing solutions for attitude estimation and external acceleration rejection, we adopt the deviation of attitude, gyro bias, and ...

On the Design of Attitude-Heading Reference Systems Using the Allan Variance
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2016The Allan variance is a method to characterize stochastic random processes. The technique was originally developed to characterize the stability of atomic clocks and has also been successfully applied to the characterization of inertial sensors. Inertial navigation systems (INS) can provide accurate results in a short time, which tend to rapidly ...

Rotation and acceleration based adaptation for attitude and heading reference system
2013 21st Signal Processing and Communications Applications Conference (SIU), 2013In this paper, a new adaptive method is proposed for Attitude and Heading Reference System (AHRS) using MEMS IMU sensors. In this work, Euler angles calculation using gyro-scope outputs is combined with the estimation of these angles by using accelerometer and magnetometer. Kalman filtering technique is used for this fussion.

Human movement detection using attitude and heading reference system
Proceedings of the 7th International Conference on PErvasive Technologies Related to Assistive Environments, 2014Among 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.
