1. Unscented Kalman Filter for Determination of Spacecraft Attitude Using Different Attitude Parameterizations and Real Data
ABSTRACT The non-linear estimators are certainly the most important algorithms applied to real problems, especially those involving the attitude estimation of spacecraft. The purpose of this paper was to use real data of sensors to analyze the behavior of Unscented Kalman Filter (UKF) in attitude estimation problems when it is represented in different ways a

2. Estimation of Pico-Satellite Attitude Dynamics and External Torques via Unscented Kalman Filter
ABSTRACT: In this study, an Unscented Kalman Filter (UKF) algorithm is designed for estimating the attitude of a pico-satellite and the in-orbit external disturbance torques. The estimation vector is formed by the satellite's attitude, angular rates, and the unknown constant components of the external disturbance torques acting on the satellite. The gravity

3. Analyzing the Unscented Kalman Filter Robustness for Orbit Determination Through Global Positioning System Signals
ABSTRACT: The nonlinear unscented Kalman filter (UKF) is evaluated for the satellite orbit determination problem, using Global Positioning System (GPS) measurements. The assessment is based on the robustness of the filter. The main subjects for the evaluation are convergence speed and dynamical model complexity. Such assessment is based on comparing the UKF

4. Mecanização de central de navegação inercial com dados a partir da integração de IMU MEMS e receptor GPS / Inertial navigation mechanization through the intergration of an IMU MEMS and a GPS receiver.
The proposal of this work is to present a procedure for integration of the acceleration and angular rate measurements of a low cost Inertial Measurement Unit (IMU) based on MEMS (Micro Electro-Mechanical System) technology with position and speed data from a GPS receiver. Then, it details the equations that have been used to integrate the movement and the at

5. Sistema de detecção e isolamento de falhas em sistemas dinâmicos baseado em identificação paramétrica
The present research aims at contributing to the area of detection and diagnosis of failure through the proposal of a new system architecture of detection and isolation of failures (FDI, Fault Detection and Isolation). The proposed architecture presents innovations related to the way the physical values monitored are linked to the FDI system and, as a conseq
