Deterministic Global Attitude Estimation [PDF]
Proceedings of the 45th IEEE Conference on Decision and Control, 2006 A deterministic attitude estimation problem for a rigid body in an attitude dependent potential field with bounded measurement errors is studied. An attitude estimation scheme that does not use generalized coordinate representations of the attitude is presented here.

Attitude Estimation from Polarimetric Cameras [PDF]
2018 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2018 In the robotic field, navigation and path planning applications benefit from a wide range of visual systems (e.g, perspective cameras, depth cameras, catadioptric cameras, etc.). In outdoor conditions, these systems capture information in which sky regions cover a major segment of the images acquired.

Attitude Estimation or Quaternion Estimation? [PDF]
The Journal of the Astronautical Sciences, 2004 The absence of a globally nonsingular three-parameter representation of the rotation group forces attitude Kalman filters to estimate either a singular or a redundant attitude representation. We compare two filtering strategies using simplified kinematics and measurement models.
