LORAN-C ON THE LOWER GREAT LAKES

In 1970-71 a study of Loran-C reception and stability characteristics was carried out along the Lower Great Lakes. By setting up calibration stations for periods from 1 hour to 18 days between Eastern Lake Ontario and Western Lake Erie, measures were obtained of chain variability, instrument variability, signal strength and certain other effects. Calibration curves were obtained which permit correction of Loran data over Lake Ontario and Lake Erie. Monitor stations were used to determine the advantage resulting from use of the differential mode of operation. Results indicated that any propagation variability was small as compared to instrumental and chain variability. In the differential mode, overall system accuracies, geometry and signal strength appear to be attractive for precise navigation or for a large area survey operation in the Lower Lakes. The study was sponsored by the Canadian Hydrographic Service.
