Navigation, 1982
Originally developed for marine navigation and now extensively utilized in offshore air navigation, the LOng Range Aid Navigation (LORAN) system has assumed considerable importance in the area of timing synchronization. LORAN-C chains are maintained by the U.S. Coast Guard. Wherever possible, the chains are monitored by the U.S.

Navigation, 1976
The coast guard has been tasked to implement expanded Loran–C coverage to include the West Coast and Gulf of Alaska. This network of eight transmitting stations will employ the Loran–C Replacement (LRE) and an improved version of Loran Transmitting Set AN/FPN-44 which has been designated as AN/FPN-44A.

Journal of Navigation, 1991
In 1987 a special meeting of IALA held at Trinity House in London expressed a common purpose to enhance and expand existing Loran-C coverage in North-West Europe and the North Atlantic. After two years of negotiation, agreement was finally reached in January of this year to proceed with the project.

Loran-C Replacement Equipment (LRE)
Navigation, 1976A program was initated by the U.S. Coast Guard during 1973 to develop a Loran-C Replacement Equipment (LRE) package to replace or improve the existing Loran-C ground station equipment. The overall goal of this program is to improve LORSTA operational performance while simultaneously reducing personnel and equipment operating costs.

Navigation, 1982
Loran-C is a radionavigation system that has been operational since 1958. The initial development was started during World War II and since that time the system has evolved through several stages. The number of applications and the extent of the system have also significantly increased.

The automated Loran-C coverage diagram generator
IEEE Symposium on Position Location and Navigation. A Decade of Excellence in the Navigation Sciences, 2002The preliminary details of an automated system developed for generating and archiving Loran-C coverage diagrams are presented. A coverage diagram is a graphical representation of the geographical area inside of which a Loran-C receiver can function within specified limits.

Aiding GPS with Calibrated Loran-C
Navigation, 1988GPS is currently being installed; when it is operational, five satellites will be in view virtually 100 percent of the time. However, the full constellation will not be in place for several years, and even then satellite failures may introduce coverage holes.

Navigation, 1988
The following is a speech given before The Institute of Navigation's January 1988 National Technical Meeting, by Webster B. Todd, Jr., of the Aircraft Owners & Pilots Association (AOPA). Mr. Todd discusses the application of Loran-C in the National Airspace System from the point of view of the general aviation user.

Time synchronization from Loran-C
IEEE Spectrum, 1968Loran-C navigational transmissions, at a frequency of 100 kHz, can be used to provide clock synchronization over long distances to accuracies within ±1 ?s. Results to date represent improvements as great as three magnitudes over other operational long-range radio systems.

Using GPS to calibrate Loran-C
IEEE Transactions on Aerospace and Electronic Systems, 1991Various techniques for using simultaneous Global Positioning System (GPS)/Loran data to estimate the propagation uncertainties that limit the absolute accuracy of Loran-C are discussed. Significant improvements in the absolute accuracy of Loran can be achieved with very simple calibrations.
