This study surveys the developments in the gyroless attitude determination system,
especially for small satellites. Two kinds of gyroless satellite attitude determination …

Fault Detection and Isolation (FDI) is important in many industries to provide safe operation
of a process. To determine the kind, size, location and time of fault, many Fault detection and …

Unscented Kalman filter (UKF) has been extensively used for state estimation of nonlinear
stochastic systems, which suffers from performance degradation and even divergence when …

One of the critical challenges in spacecraft attitude estimation is the handling nonlinear non-
Gaussian noisy conditions originating from measurement errors, model drifts, and incorrect …

A modified unscented Kalman filter is presented to estimate the quaternion parameters as
well as the angular velocities of a rigid gyro-less satellite under faulty sensor conditions. The …

Abstract The integration of Global Positioning System (GPS) with Inertial Navigation System
(INS) has been very intensively developed and widely applied in multiple areas. To further …

The battery pack may reduce an available capacity due to each individual cell imbalance
and cause safety problems of the battery pack itself, so it is necessary to design a battery …

The attitude and size of satellite targets are essential information for their activity analysis.
This article proposes a novel approach to estimate the absolute attitude and size of satellite …

As a typical safety-critical system, satellite has extremely stringent requirements for
reliability. However, some satellite components, especially attitude sensors, are prone to …

This paper proposes using TRIAD and Unscented Kalman Filter (UKF) algorithms in a
sequential architecture as a part of a small satellite attitude estimation algorithm. This …
