48、 HANDBOOK 1. SCOPE Various NASA programs at KSC make maximum use of existing ground systems (GS). Conse-quently, the designer must determine whether existing cables can be used as is or be modified, or if new cables are required. This handbook contains a list of specifications, standards, and reference documents that shall be used in the design, fabrication, and assembly of GS cables at the Kennedy Space Center (K
