THE problem of controlling a multibody spacecraft that must maintain pointing requirements
for each of its bodies is addressed. The spacecraft model considered in this Note consists of …

A highly accurate, gyroless, attitude determination and control system for advanced
environmental satellites is developed and validated by analysis and simulation. The features …

This paper presents the results of a study to develop and evaluate an attitude and attitude
rate estimation technique for a multi-body spacecraft that includes a real time angular rate …

THIS report reviews the methods of Kalman filtering in attitude estimation and their
development over the last two decades. This review is not intended to be complete but is …

An extended Kalman filtering technique is addressed for gyroless spacecraft to estimate the
angular rate and attitude vectors of spacecraft and the alignment of reaction wheels using …

Attitude determination, along with attitude control, is critical to functioning of every space
mission. In this paper, we investigate and compare, through simulation, the application of …

This paper presents a Kalman filter using a seven-component attitude state vector
comprising the angular momentum components in an inertial reference frame, the angular …

In this paper, fine attitude estimation using low-cost sensors for attitude pointing missions of
spacecraft is addressed. Attitude kinematics and gyro models including bias models are in …

An Unscented Kalman Filter (UKF) is derived in an attempt to solve the spacecraft dual
estimation problem with greater accuracy than is attainable with an Extended Kalman Filter …

THE stringent attitude pointing accuracy requirements of a nadir-pointing satellite demand
real-time precise attitude determination from output information of the attitude measurement …
