Abstract

The Giant Magellan Telescope will be a 25.4-m visible and infrared telescope at Las Campanas Observatory in Chile. The initial alignment of this doubly segmented telescope will be challenging, particularly when mapping coordinate systems together. To ease the complications of alignment, a laser tracker network has been developed to accurately determine the coordinate systems of subsystems and tie them into a reference coordinate system to ensure a successful and efficient first photons phase of the telescope. This paper will discuss the simulations that have been run to date of this laser tracker network and our general initial alignment strategy.
