A Quadrant-CCD star tracker
نویسندگان
چکیده
We discuss the characteristics of a Quadrant-CCD developed by Tektronix for pointing and tracking applications. The device is discussed in the context of its application to the Johns Hopkins University adaptive optics program, where it is being used for the correction of stellar image motion resulting from atmospheric turbulence. The transfer function of the device is discussed and results are presented which demonstrate the Quadrant-CCDs capability to provide offset signals to control a rapid guiding mirror in the Johns Hopkins instrument.

متن کاملA Brightness-Referenced Star Identification Algorithm for APS Star Trackers
Star trackers are currently the most accurate spacecraft attitude sensors. As a result, they are widely used in remote sensing satellites. Since traditional charge-coupled device (CCD)-based star trackers have a limited sensitivity range and dynamic range, the matching process for a star tracker is typically not very sensitive to star brightness. For active pixel sensor (APS) star trackers, the...
متن کاملFitting parametric curve models to images using local self-adapting separation criteria
The task of fitting parametric curve models to boundaries of perceptually meaningful image regions is a key problem in computer vision with numerous applications, such as image segmentation, pose estimation, 3-D reconstruction, and object tracking. In this thesis, we propose the Contracting Curve Density (CCD) algorithm and the CCD tracker as solutions to this problem. The CCD algorithm solves ...

The tip-tilt correction system at the Infrared Optical Telescope Array (IOTA) has been upgraded with a new star tracker camera. The camera features a backside-illuminated CCD chip offering doubled overall quantum efficiency and a four times higher system gain compared to the previous system. Tests carried out to characterize the new system showed a higher system gain with a lower read-out noise...

Star identification is one of the most important stages in attitude determination with star trackers. This can be performed using matching algorithms between observed stars and a master star catalogue. The main challenge in this approach is to provide a fast and reliable identification algorithm that is sufficiently robust in different pointing views of the star tracker optical system in the sp...
