An Optical Wide-field patroL-Network (OWL-Net) has been developed for maintaining Korean low Earth orbit (LEO) satellites’ orbital ephemeris. The OWL-Net consists of five optical tracking stations. Brightness signals of reflected sunlight of the targets were detected by a charged coupled device (CCD). https://www.roneverhart.com/Taylor-AD24ce-American-Dream-Acoustic-Electric-Guitar-Shaded-Edgeburst-p19272/
