Enabling Gaia observations of naked-eye stars

The ESA Gaia space astrometry mission will perform an all-sky survey of stellar objects complete in the nominal magnitude range G = [6.0 - 20.0]. The stars with G < 6.0, i.e. those visible to the unaided human eye, would thus not be observed by Gaia. We present an algorithm configuration for the Gaia on-board autonomous object observation system that makes it possible to observe very bright stars with G = [2.0-6.0). Its performance has been tested during the in-orbit commissioning phase…

Uniform Star Catalogue using GWKM Clustering for Application in Star Sensors
- Physics, Computer ScienceJournal of Navigation
- 2019
A novel algorithm of weighted k-means clustering with geodesic criteria is presented to generate a uniform database for a star sensor and it was found that the uniformity leads to a significant reduction of the probability of observing a large number of stars in all fields of view.
