IMage-based satellite attitude estimation
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010Pushbroom sensors are widely used for earth observation from space; this camera captures 1-D image and uses straight motion of the satellite to build a 2-D image. Yet, attitude variations of the satellite during the aquisition process can lead to significant distortions in the 2-D image.

Spin-axis attitude estimation is examined in a manner analogous to the study of three-axis attitude estimation. Measurement modeling issues are given careful consideration, as are those of representation, frame, and constraint. Three approaches to spin-axis attitude estimation are presented and compared numerically.

IEEE 2000. Position Location and Navigation Symposium (Cat. No.00CH37062), 2002
In most military aircraft an inertial navigation system (INS) is the main source for attitude and heading data. Aircraft attitude and heading are important quantities, and in the case of a failure in the INS, backup values are needed. We here present how these can be calculated using other sensors in the aircraft.

Optimal Linear Attitude Estimator
Journal of Guidance, Control, and Dynamics, 2007An optimal linear attitude estimator is presented for the case of a single-point real-time estimation of spacecraft attitude using the minimum-element attitude parameterization: Rodrigues (or Gibbs) vector g. The optimality criterion, which does not coincide with Wahba's constrained criterion, is rigorously quadratic and unconstrained. The singularity,

Kalman Filtering for Spacecraft Attitude Estimation
Journal of Guidance, Control, and Dynamics, 1982HIS 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 limited to algorithms suitable for spacecraft equipped with three-axis gyros as well as attitude sensors.

Constraint in Attitude Estimation Part II: Unconstrained Estimation
The Journal of the Astronautical Sciences, 2003A complete and careful foundation is presented for maximum-likelihood attitude estimation and the calculation of measurement sensitivity matrices with the intent of revealing heretofore undisclosed pitfalls associated with unconstrained quaternion estimation.

Unscented Attitude Estimator Based on Dual Attitude Representations
IEEE Transactions on Instrumentation and Measurement, 2015This paper investigates an unscented attitude estimator based on modified Rodriguez parameter (MRP) and quaternion using a linearized attitude representation transformation. When the singularity transformation conditions do not occur, the developed filter can benefit from the MRP representation in terms of decreased calculation burden and improved ...
