“…The attitude and position of an AAV can be determined by either ground-based, or AAV-based, hardware. Laser tracking has been successfully implemented to determine the position and pose of a body in motion (Shirinzadeh, 1998;Shirinzadeh & Teoh, 2001). Information obtained in this manner can be differentiated to determine the velocity and angular rates of the body (Wang & Shirinzadeh, 2012;Zhang, Wang, & Cai, 2009).…”

The performances of three attitude determination algorithms are compared in this paper. The three methods are the Complementary Filter, a Quaternion-based Kalman Filter and a Quaternion-based Gradient Descent Algorithm. An analysis of their performance based on an experimental investigation was undertaken. This paper shows that the Complementary Filter requires the least computational power; Quaternion-based Kalman Filter has the best noise filtering ability; and the Quaternion-based Gradient Descent Algorithm produced estimates with the highest accuracy. As many attitude determination methodologies make use of the quaternion rotation representation, the attitude quaternion to Euler angle singularity property has been investigated. Experiments conducted show that when Y-rotation approach the singularity position (±90°), the X-rotation drifts away from the reference input. This paper proposes the use of an imaginary set of sensor measurements to replace the original sensor measurements as the Y-rotation approaches the singularity. The proposed methodology for overcoming the conversion singularity has been experimentally verified.

Abstract.A method for improving resolution of grating interferometer displacement measuring system is developed in this paper. The measurement system consists of a grating interferometer and a phase-shift device. Two interference fringes are required in the detecting field of photoelectric sensor. If we change the signal phase of the interference fringe by moving the photoelectric sensor between the two interference fringes, the displacement equivalent converted from the photoelectric sensor will changed. The method is applied in positioning system and the experiments' results indicate that the new displacement measuring method will improve the positioning accuracy about 33%. Also, the errors in the positioning process with the new method are discussed in briefly.

Abstract.A new method for improving resolution of displacement measuring system is developed in this paper. The core parts of the system is a grating interferometer and a phase-shift device. Moving the photoelectric sensor, between the two interference fringes, the signal phase of the interference fringe will be changed. The method leads to higher resolution in theory than that with laser interferometer. Experiments with the method are made in a positioning system and the' results show that the new displacement measuring method will improve the positioning accuracy about 16%.
