The Coast Guard has exerted a major effort to ensure that navigation charts with Loran-C lines overprinted on them are available for distribution as soon as possible for areas covered by existing Loran-C chains and throughout the remainder of the Coastal Confluence Zone as Loran-C coverage becomes available. The accurate charting of Loran-C lines- of-position is more difficult than one would think and this paper discusses some of these difficulties encountered. It also describes the method currently being used to introduce additional secondary phase (ASF) corrections into the charting process to improve the accuracy of the lines. Printing schedules, both present and tentatively planned for the future, are covered.
