Attitude Estimation Using Inertial and Barometric Measurements
Melone Nyoba Tchonkeu, Soulaimane Berkane, Tarek Hamel
Accurate and robust attitude estimation is a key challenge for autonomous vehicles, particularly in GNSS-denied conditions and during highly accelerated flight. In such conditions,…
Galilean State Estimation for Inertial Navigation Systems with Unknown Time Delay
Giulio Delama, Martin Scheiber, Yixiao Ge +3
Many Inertial Navigation Systems (INS) use Global Navigation Satellite System (GNSS) position as the primary measurement to drive filter performance and bound error growth. However…
Relative Pose-Velocity Estimation Using Dual IMU Measurements and Relative Position Sensing
Alessandro Melis, Tarek Bouazza, Soulaimane Berkane +1
This paper addresses the problem of estimating the relative pose (position and orientation) and velocity of a vehicle with respect to a moving target, where both are equipped with…
Equivariant Observer Design on SL(3) for Image Intensity-Based Homography Estimation
Tarek Bouazza, Pieter van Goor, Robert Mahony +1
This paper addresses the problem of homography estimation using a nonlinear observer designed on the Lie group that exploits the full image information through dir…
Complementary Filtering on SO(3) for Attitude Estimation with Scalar Measurements
Alessandro Melis, Soulaimane Berkane, Tarek Hamel +1
This paper proposes a complementary filter on SO(3) for attitude estimation from scalar measurements corresponding to projections of known inertial vectors onto body-frame sensing…
Scalar-Measurement Attitude Estimation on with Bias Compensation
Alessandro Melis, Tarek Bouazza, Hassan Alnahhal +3
Attitude estimation methods typically rely on full vector measurements from inertial sensors such as accelerometers and magnetometers. This paper shows that reliable estimation can…
Pitot-Aided Attitude and Air Velocity Estimation with Almost Global Asymptotic Stability Guarantees
Melone Nyoba Tchonkeu, Soulaimane Berkane, Tarek Hamel
This paper investigates the problem of attitude and air velocity estimation for fixed-wing unmanned aerial vehicles (UAVs) using IMU measurements and at least one Pitot tube measur…
