Star-tracking algorithm are essential for orientation computation of devices such as autonomous platforms such as nano-satellites, drones, vessels and automobiles.

Using commercial-off-the-shelf (COTS) mobile devices such as smartphones for star trackign is especially challenging because it requires robustness and should work continuously and autonomously. This dataset can be used for exploring and testing of such algorithms.

The frames in this data set were all taken by hand and on different conditions ( clear and cloudy nights) , therefore different glare is expected .

In S9 folder : for each frame we added a text file with the stars coordinates x,y, radius (in pixels). This text file was generated for each image using simple image processing algorithm that search for the brightest pixels (as connected components) in each frame and compute the center of each star in sub-pixel.
