Space Debris Observation activities at S5Lab: from telescope measurements to orbit and attitude determination

Nowadays, the space debris issue is on top of the list of all space agency in the world. Even more so with the advent of the new space economy which will increase even more the number of objects around the Earth and consequently impact risk between operative satellite and space debris. S5Lab has developed several tools in order to identify, classify and monitor object in orbit. Measurements acquisition occurs by means of a network of telescope around the Earth surface. In this paper will be shown all S5Lab's activities starting from image and measurements acquisition until attitude determination retrieved from the light-curve, passing for orbit determination and measure calibration. Moreover, a TLEs improvement procedure will be exposed.
