Abstract

Rockwell International fielded an integrated avionics system (IAS) on the CH-47D Chinook helicopter aircraft in 1985. The most recent modification to the IAS is the integration of the NAVSTAR global positioning system (GPS) as the precise navigation/time reference. The author begins with an overview of the CH-47D integrated avionics system prior to the GPS integration. A detailed description is given for the integration design of the GPS, including a discussion on how the capabilities of the GPS enhance the performance of the integrated avionics system and improve the mission capabilities of the aircraft under the most demanding conditions, including mission-peculiar flight profiles and four-dimensional maneuvers using GPS as the precise navigational/time reference
