We implemented an extended Kalman filter (EKF) hardware for a real-time attitude heading
reference system (AHRS). Attitude estimation is an important process for small unmanned …

Attitude estimation is an important part for navigation of mobile robotics and unmanned
aerial vehicle (UAV) control. Although the Extended Kalman Filter (EKF) can be done …

Different navigation systems have different requirements for attitude estimation, positioning,
and control. To achieve high-accuracy at low-cost, several low-cost MEMS Inertial …

Unmanned Ariel Vehicles (UAVs) are recently being studied and worked upon to make them
safe and secure for the upcoming expected growth of UAVs in civilian airspace. These …

An Attitude and Heading Reference System (AHRS) comprising accelerometers, gyroscopes
and magnetometers can provide roll, pitch and heading information. AHRS is utilized in …

In future versions of Saab Gripen, the mechanical artificial horizon will be replaced by a
computer calculated attitude and heading, independent of the inertial navigation system …

This paper describes the development and hardware-in-the-loop testing of an Extended
Kalman Filter (EKF) for attitude estimation. After literature review, a multi-mode solution to …

Attitude estimation plays an important role for the stable flight of a UAV. This paper proposes
an adaptive Kalman filter (AKF) to estimate the attitude of a UAV by combining inaccurate …

This paper presents the real-time implementation of a powerful nonlinear complementary
filter on special orthogonal group of rotation matrices, called as NCF SO (3) for attitude …

Unmanned Aerial Vehicles (UAVs) require high performance Attitude and Heading
Reference System (AHRS) in automatic flight. This paper presents an attitude estimate …
