A New Approach to Laminar Flowmeters
(Molecular Diversity Preservation International, 2010)
After studying the performance and characteristics of actual laminar flowmeters a new disposition for this type of sensors is proposed in such a way that the measurement errors introduced by the intrinsic nature of the ...
A Kalman Filter for Nonlinear Attitude Estimation Using Time Variable Matrices and Quaternions
(MDPI, 2020)
[Abstract] The nonlinear problem of sensing the attitude of a solid body is solved by a novel implementation of the Kalman Filter. This implementation combines the use of quaternions to represent attitudes, time-varying ...
Towards Precise Positioning and Movement of UAVs for Near-Wall Tasks in GNSS-Denied Environments
(MDPI, 2021-03)
Abstract: UAVs often perform tasks that require flying close to walls or structures and in environments where a satellite-based location is not possible. Flying close to solid bodies implies a higher risk of collisions, ...
