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

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

Star-Identification System Based on Polygon Recognition
Aerospace, 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.
