Today was the fist day of our experiment. Our team  gathered at 9am and had a last check on the four targets. The targets were already tied to the moorings by 12pm (the time Sentinel-2 was expexted to pass over Tsamakia beach). As for today, the targets were next to each other with no space in between them forming a 5x20m target. An image was  also taken from one of our drones, which had an optical RGB camera mounted on, in order to compare our data with Sentinel-2’s data.
