Abstract:

For Phase I testing, five aircraft types were identified by the GPS JPO as potential host vehicles - three Air Force transport types, one Air Force helicopter, and one Navy land-based patrol plane. The Navy aircraft was added to the Air Force group as an addendum to the original task effort. The integration study was intended to identify pertinent factors that might influence Set Z design and installation in a manner that would minimize test vehicle integration costs and simplify the GPS Phase I test effort. The integration study involved a detailed review of technical orders and maintenance manuals of the five host aircraft. T.O.s and specifications that described related or interfacing electronics systems and intruments were examined and the data were verified by ARINC Research during visits to aircraft system managers and manufacturer facilities. The proposed form, fit, and function of Set Z equipment were derived from manufacturers proposals and both ARINC and GPS specifications, and through engineering discussions with GPS UE Set Z contractor Magnavox Corporation personnel. The test aircraft configurations of radio navigation systems were then developed, environmental conditions were determined, and a physical installation was described for each vehicle. The GPS JPO directed that a TACAN equipment be removed from each USAF aircraft so the Set Z would have adequate installation space and so that integration could be simplified through the use of existing TACAN wiring. If possible, the CDU was to be located in the aircraft cockpit, available to the pilot and copilot.
