The report contains the results of an evaluation of a Loran A and C Simulator designed to provide signals for dynamic testing of Loran receivers and ancillary equipment. Equipment difficulties discovered during the evaluation are described, and modifications that would improve the Simulator usefulness are suggested. The Simulator output was the equivalent of signals from both Loran-A and Loran-C stations. This output involved selected simulation of the existing East Coast Loran-C triad or two Loran-A station pairs and movement of an aircraft through these Loran signal coverage areas. The simulated signal included variable aircraft speed, fixed altitudes, radio frequency noise, signal strength variations, CW interference signals, and sky waves. Use of the Simulator for dynamic laboratory testing of Loran A and C Receivers is recommended including equipment modifications and revisions to the instruction manual. Author
