Paper Abstract

As part of the Very Large Telescope Interferometer (VLTI), ESO signed in June 1998 a contract with AMOS S.A. covering the design, manufacturing and testing of the Auxiliary Telescope System (ATS), including three movable auxiliary telescopes (AT) and the associated site equipment. The project entered into manufacturing phase in mid-1999. As a prime contractor, AMOS S.A. had to deliver complete and fully operational telescopes ready to plug on any of the thirty stations of the VLTI sub-array. This work required an overall system level approach involving a multi-skilled team. This paper depicts the progress status and presents the results of the main tests -- except optical testing -- performed on the telescopes in AMOS facilities. Those tests are the earliest verification of high-level requirement specifications such as optical path length (OPL) stability, pointing error, main axis dynamic response, performed on the telescope fully integrated.
