Abstract: Investigations and development of a Loran feasibility model, which were conducted to determine the impact of microcomputer concepts on performance and cost of radio navigation equipment, have demonstrated that the performance requirements for both austere and sophisticated Loran-C or Omega users can be satisfied within the economic value to these users. Continuing development of MOS/LSI semiconductor technology has provided microcomputer sets, central processor units and compatible semiconductor memories whose architecture is in accordance with the requirements for radio navigation processing. The result of this feasibility demonstration was a microcomputer configuration which served as a base for consideration of a low cost Omega navigator and a combined Loran/Omega navigator. The resultant configurations for these navigators has the potential to satisfy user cost objectives for either Loran-C or Omega navigation equipment, and a combined Loran/Omega navigator. Further, it is clearly demonstrated that mechanization of navigator functions such as conversion to latitude and longitude, and steering can be provided at minimal cost to the user.
