摘要

1. In work done for the USCG, Loran was the only DGPS backup system that consistently satisfiec the TLS criterion for large vessels transiting the most challenging harbors under low visibility conditions. 2. For several of the HEA conditions we considered, DGPS, either stand-alone or with non-Loran backups, was unable to satisfy the TLS. 3. If we require the TLS criterion to be satisfied under ail HLA conditions, Loran backup to DGPS is absolutely required.
