Construction of the Guide Star Catalog for Double Fine Guidance Sensors Based on SSBK Clustering [PDF]

open access: yesSensors, 2022
In the Chinese Survey Space Telescope (CSST), the Fine Guidance Sensor (FGS) is required to provide high-precision attitude information of the space telescope. The fine star guide catalog is an essential part of the FGS. It is not only the basis for star

Research on Partitioning Algorithm Based on Dynamic Star Simulator Guide Star Catalog

open access: yesIEEE Access, 2021
The simulated star map generated by the dynamic star simulator cannot meet the current demand for calibration of the star map recognition rate of the star sensor due to the huge amount of guide star catalog data and the slow retrieval process. This paper

A Galactic O Star Catalog [PDF]

open access: yesAstrophysical Journal, Supplement Series, 2004
We have produced a catalog of 378 Galactic O stars with accurate spectral classifications which is complete for V<8 but includes many fainter stars. The catalog provides cross-identifications with other sources; coordinates (obtained in most cases from Tycho-2 data); astrometric distances for 24 of the nearest stars; optical (Tycho-2, Johnson, and ...

Star Catalog Criteria Selection and Mission Catalog Update for a Typical Star Tracker [PDF]

open access: yesفصلنامه علوم و فناوری فضایی, 2013
Star tracker is an attitude determination device which determines the satellite or spacecraft’s attitude using the star position information in inertial and body references. Star information is collected and stored onboard as a “Star or mission catalog”.

An Ap Star Catalog Based on LAMOST DR9

open access: yesThe Astrophysical Journal, 2023
We present a sample of 2700 Ap stars in the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) DR9 catalog. The candidates are first selected to be in a temperature range typical of Ap stars by using the BP − RP color index from Gaia DR3.

A Voting-Based Star Identification Algorithm Using a Partitioned Star Catalog

open access: yesApplied Sciences (Switzerland)
With the rapid advancement of aerospace technology, the maneuverability of spacecraft has increasingly improved, creating a pressing demand for star sensors with a high attitude update rate and high precision. Star identification, as the most complex and

Research on Full-Sky Star Identification Based on Spatial Projection and Reconfigurable Navigation Catalog

open access: yesRemote Sensing
A star tracker is widely used as a high-precision attitude measurement device for spacecraft. It calculates attitude by extracting the magnitude and the position of presumed detected stars by a CCD/CMOS sensor and matching them with stars in the star ...

Catalog of Galactic β Cephei Stars [PDF]

open access: yesThe Astrophysical Journal Supplement Series, 2005
We present an extensive and up-to-date catalog of Galactic Beta Cephei stars. This catalog is intended to give a comprehensive overview of observational characteristics of all known Beta Cephei stars. 93 stars could be confirmed to be Beta Cephei stars. For some stars we re-analyzed published data or conducted our own analyses.

Star-Identification System Based on Polygon Recognition

open access: yesAerospace, 2023
Accurate attitude determination is crucial for satellites and spacecraft. Among attitude determination devices, star sensors are the most accurate. Solving the lost-in-space problem is the most critical function of the star sensor.
