Aims: Tuning the system noise covariance Q matrix for the single-frame method aided Kalman filtering algorithm. Background: The covariance matching procedure of the measurement noise covariance, namely the R matrix, was processed in singular value de

The attitude estimation of a spacecraft in low Earth orbit is considered with the design of two different adaptation rules in the extended Kalman filter (EKF) algorithm. The adaptations are designed for compensating both the measurement faults and ex

This study investigates the effects of magnetic disturbances resulting from geospace storms on the satellite attitudes estimated by EKF. It is shown that the increasing levels of geomagnetic activity affect geomagnetic field vectors predicted by IGRF

A three-axis attitude estimation scheme is presented using a set of albedo interfered coarse sun sensors (CSSs) of Earth, which are inexpensive, small in size, and light in power consumption. For modeling the interference, a two-stage albedo estimati

In this study, an estimation algorithm based on a two-stage Kalman filter (TSKF) was developed for wind speed and Unmanned Aerial Vehicle (UAV) motion parameters. In the first stage, the wind speed estimation algorithm is used with the help of the Gl
