Star trackers are currently the most advanced attitude measuring instruments. They have the advantages of high precision, small quality, no drift, strong antiinterference and autonomous navigation without relying on other navigation systems. This paper proposes the design of a low-quality, small-size and high-accuracy star tracker that is constructed by a self-developed CMOS APS (Complementary ...

We present the recent heavy flavor measurements in the STAR experiment and briefly discuss the STAR future heavy flavor physics program with the newly installed Heavy Flavor Tracker and Muon Telescope Detector.

In this paper, a star tracker attitude estimation procedure with increased robustness and efficiency, using the AIM (Attitude Estimation using optimal Image Matching) algorithm, is presented and validated. The unique approach of the AIM algorithm allows us to introduce a reliable quality check which can be efficiently calculated. Unlike existing validation methods, this quality check not only d...

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...

We propose to construct a heavy flavor tracker for the STAR experiment at RHIC in order to measure the elliptic flow of charmed hadrons in the low pT region and identify B-meson contributions in the region pT > 4 GeV/c. In this talk, we will present the design of the detector in-depth and its expected performance as studied in detailed simulations and analytic calculations. Physics potentials o...

Introduction: The Joint Milli-Arcsecond Pathfinder Survey 1 (JMAPS) is a Department of the Navy space astrometry mission to conduct an all-sky, bright star astrometric and spectrophotometric survey. The primary goal of the mission is to update the bright star catalog currently used by Department of Defense, NASA, and commercial star tracker manufacturers for spacecraft attitude determination.
