Non-Linear Control Strategies for Attitude Maneuvers in a CubeSat with Three Reaction Wheel
(Universidad Nacional de San Agustín de ArequipaPE, 2021)
Development of nanosatellites with CubeSat stan-dard allow students and professionals to get involved into the aerospace technology. In nanosatellites, attitude plays an im-portant role since they can be affected by various ...
Meta-Intelligence: Understanding, Control, and Interactivity between Creative, Analytical, Practical, and Wisdom-Based Approaches in Problem Solving
(2021)
A deeper understanding of the processes leading to problem framing and behind finding solutions to problems should help explain variability in the quality of the solutions to those problems. Using Sternberg’s WICS model ...
Low cost attitude estimation system. Performance evaluation on an airbearing based testbed
(Universidad de Buenos. Facultad de Ingeniería, 2015)
In this work, a low-cost attitude navigation system for spacecrafts is presented. The system fuses measurements from a three axis MEMS gyroscope and a CCD camera that identifies a known pattern of points (which emulate the ...
Traditional Nets Interfere with the Uptake of Long-Lasting Insecticidal Nets in the Peruvian Amazon: The Relevance of Net Preference for Achieving High Coverage and Use
(Public Library of Science, 2013)
While coverage of long-lasting insecticide-treated nets (LLIN) has steadily increased, a growing number of studies report gaps between net ownership and use. We conducted a mixed-Methods: social science study assessing the ...
The ITASAT CubeSat Development and Design
(Inst Aeronautica & Espaco-Iae, 2017)
Because they are inexpensive platforms for satellites, CubeSats have become a low-cost way for universities and even developing countries to have access to space technology. This paper presents the ITASAT design, particularly ...
The effect of belief in weight controllability on anti-fat attitudes: An experimental manipulation
(2017-05)
Introduction Anti-fat attitudes reflect a type of discrimination on the basis of body weight and are one of the last accepted types of social stigma. Objective To evaluate the effect of exposure to priming messages about ...
Attitude control of inverted pendulums using reaction wheels: Comparison between using one and two actuators
(2019-01-01)
The attitude control using reaction wheels as actuators has been one of the most popular ways to stabilize and repel external disturbances in aerospace devices. From the controlled change of the angular momentum rate of ...
An engineering vector-like approach to attitude kinematics & nominal attitude state tracking control
(Instituto Tecnológico de AeronáuticaCuritibaPrograma de Pós-Graduação em Engenharia Aeronáutica e Mecânica, 2002-10)
In dealing with rigid body three-dimensional rotational motion, one is inevitably led to face the fact that rotations are not vector quantities. They may, however, be treated as such when the angle of rotation is (very) ...
Rao-blackwellized particle filter for the cbers-4 attitude and gyros bias estimation
(2020-01-01)
The Rao-Blackwellized particle Filter (RaoBPF) and the Unscented Kalman Filter (UKF) were developed in this work to attitude and gyros bias estimation using simulated orbit and attitude measurement data for CBERS-4 (China ...
