Test Bed Telescopes (TBT)

ESA's Test Bed Telescopes (TBT) are two twin telescopes built by ESA to test different observational activities in the optical detection of NEO’s and satellites or space debris. The two telescopes are located in Spain (Z58 - ESA TBT Cebreros Observatory)  and Chile (W57 - ESA TBT La Silla Observatory).
