The experiment currently consists of four telescopes located in Australia, Namibia, Turkey, and at the McDonald Observatory near Fort Davis, Texas.
[1] The Namibian telescope is located at the High Energy Stereoscopic System site in the Gamsberg mountains south-west of the capital Windhoek.
[1] The ROTSE project is a collaboration of astrophysicists from the University of Michigan, Los Alamos National Laboratory, Lawrence Livermore National Laboratory, the University of New South Wales (Australia) and the Max Planck Institute for Nuclear Physics (Germany).
[2] The original ROTSE-I had 4 telephoto lenses of 11 cm aperture, covering a 16x16 degree field of view.
Therefore, ROTSE-II was designed, also featuring a large field of view, but it was never built, since new satellites such as HETE-2 and SWIFT could provide smaller error boxes, making a huge field of view unnecessary.
