Error coupling analysis of the laboratory calibration method for a star tracker.
Applied Optics, 2021A star tracker should be well calibrated before it is equipped in order to achieve high accuracy. There exists, however, the coupling problem between the internal and external parameters for most commonly used laboratory calibration methods, which affect

Autonomous Star Tracker Performance
57th International Astronautical Congress, 2006Abstract First in NASA's New Frontiers series of missions, the New Horizons spacecraft was successfully launched on January 19, 2006. New Horizons is scheduled to perform a gravity assist at Jupiter on February 28, 2007, arrive at Pluto on July 14, 2015; completing an extended mission to at least one Kuiper Belt Object in subsequent years.

In many applications of star trackers, extremely short acquisition times, as well as accuracy and sensitivity, are required. Tracking systems employing the vidicon as a radiation sensor have been shown to provide the necessary speed of acquisition for such applications.

This paper describes a star tracker (ST) as a major sub-system of an autonomous satellite navigation system. The navigation system is comprised of a star tracker which determines the satellite attitude and a Global Positioning System (GPS) receiver which determines the satellite's position.

SPIE Proceedings, 1986
A high precision star tracker has been developed as part of the attitude measurement and control system of the German Roentgen-Satellit ("ROSAT"). A Peltier cooled CCD array in the focal plane of an 82 mm refractive lens is used to measure the position of up to 3 stars within a field of view (FOV) of 5.9° x 4.4°. The position of a fourth reference star

Autonomous Star Tracker Development
IFAC Proceedings Volumes, 1992Abstract The attitude control, pointing control, and navigation systems of future advanced spacecraft will be characterized by a high degree of autonomy, very high accuracy, efficient commandability, and fast fault recovery. These characteristics are incompatible with the constraints of conventional star trackers which mandate a-priori definition and

GOCE star tracker attitude quaternion calibration and combination
Advances in Space Research, 2019We analyse the inter-boresight angles (IBA) measured by the star trackers on board the GOCE satellite and find that they exhibit small offsets of 7–9″ with respect to the ones calculated from the rotation of the star tracker reference frames to the ...

Star tracker for mobile applications
2016 IEEE International Conference on the Science of Electrical Engineering (ICSEE), 2016This paper presents a star tracking algorithm to determine the orientation of aircrafts, spacecrafts and automobiles. Such tracking is especially challenging since it requires robustness and should work continuously and autonomously. A wider view of this problem is utilizing the algorithm on automobiles and aircrafts and predict the device's ...
