The OCA-DLR Asteroid Survey (ODAS) was an astronomical survey to search for small Solar System bodies focusing on near-Earth objects in the late 1990s. This European scientific project – a collaboration between the French Observatoire de la Côte d'Azur (OCA) and the German Aerospace Center (DLR) – discovered a total of 956 asteroids and 1 comet during its course.[1]

ODAS operated in cooperation with a global effort regarding Near-Earth objects that was begun by the Working Group on Near-Earth Objects, a component of the International Astronomical Union.[1] The project began October 1996 and ceased observations in April 1999 for a refurbishing. However the telescope has not been reopened since that time.[2] Survey observations were made during the 15 days each month when moon light was at a minimum, during the first and last quarters of the lunar month.[1] The operation used a 90 cm Schmidt telescope of the OCA at Calern, near the city of Nice in southeastern France. A combination of a CCD camera[3] and a software package[4] were used for automated detection of moving objects.

Throughout its tenure, the project observed a total of 10,523 objects, made a total of 44,433 positional measurements, and was responsible for the discovery of 956 asteroids according to the new rules issued by the MPC in October 2010. (The rules redefines who discovered a particular object.[5] Previously, ODAS accounted for a total of 1020 asteroid discoveries). Among the discoveries are also 5 near-Earth asteroids and 8 Mars-crossers (without considering said rule). OADS also recovered several objects that were previously lost and discovered the comet 198P/ODAS[1]
