The Loran-C Midcontinent Expansion Project-a status report

The author discusses the current status and future plans of the Loran-C Midcontinent Expansion Project (MEP), a joint US Coast Guard (USCG) and Federal Aviation Administration (FAA) project designed to provide coverage to the area of the mid-US not currently serviced by Loran-C. Under an agreement with the FAA, the USCG has determined that two Loran-C chains are required to complete coverage of the 'midcontinent gap'. The USCG and FAA are proceeding with the chain and monitor configurations, land acquisition, station design, equipment procurement, and existing station upgrades necessary to complete the chains by the end of 1990. After a brief description of the system design, the author discussed the transmitting stations, the monitor sites, the control sites, certification, and aviation users.<>
