Advanced Technology Leisure Application Simulator
The Advanced Technology Leisure Application Simulator, or ATLAS, is a large hydraulic motion simulator. It was designed, as the name implies, for the theme park industry. The ATLAS is a product of Rediffusion Simulation in Sussex, England, now owned by Thales Group and known as Thales Training & Simulation.
The ATLAS was derived from military flight simulation technology. It uses six hydraulic actuators to provide a broad range of movement.
In the later half of the 1980s, Walt Disney Imagineering bought and refined this technology for two theme park attractions; Star Tours at Disneyland (and later Disney's Hollywood Studios, Tokyo Disneyland, and Disneyland Paris), and Body Wars at Epcot. The Disney attractions feature large, 40-person cabins hidden from outside view, arranged lengthwise with four or six simulators per installation. There are four simulators at Disneyland's Star Tours and EPCOT's Body Wars, while the remaining Star Tours installations have six. Body Wars is now defunct and planned for removal with the closure of the Wonders of Life pavilion.
