The GBOT group is in charge of the Ground Based Optical Tracking of the Gaiasatellite. In concrete terms, since the launch of Gaia, our task is to takeevery night, using ground based medium-class telescopes, short sequences of$10$ or $20$ images of the Gaia satellite close to its meridian transit. Forthis purpose, we mainly use the VLT Survey Telescope and the LiverpoolTelescope. In these images, taken close to the Sun's opposition - since Gaia isin L$_2$ - we observe many asteroids: between $30$ and $100$ asteroids everynight, up to magnitude $22$. In order to extract the astrometric positions aswell as the magnitudes of these asteroids, we have developed semi-automaticmethods, strategies and tools tailored explicitly for this daily task. In onlythree and a half years of operation, this system has allowed us to send to theMinor Planet Center the position and the photometry for about $20,000$asteroids, amongst which $9,000$ new objects. Here we describe all the aspectsof the GBOT asteroid survey.
