RAIL Graphical User Interface

Home Screen – Shows a complete overview of equipment status and displays: alarms, data and access to equipment control screens

The GUI is the centerpiece of RAIL and allows the operatorTo command and control the Loran station’s equipment.

Equipment Control Screens for:

•Automatic Blink System (ABS)

•Locus Casualty Control Receiver Set (CCRS)

•Frequency Standard/Time of Transmission Monitor (TTM)

•RAIL Envelope Pulse Analyzer (EPA)

•Local Site Operating Set (LSOS)

•Remote Control Interface (RCI)

Interim Equipment Rack Layout

Immediate System ImprovementsThe RAIL system, Locus CCRS & Communications Equipment provides numerous benefits:

•Replaces antiquated command & control equipment withstate-of-the-art, highly reliable, fault tolerant equipment.

•Improves the local interface with the Loran Station.

•Improves reliability and availability of the Loran signal.

•Improves remote Command and Control to LCCS.

•Improves archiving functions and integrity of data.

Future PlansThe RAIL system, along with the Communications Equipment willprovide the interface to two systems in development:

Graphical User Interface for TFE .

Graphical User Interface for the new TCS.

Local and Remote Electronic Interface for TFE.

Local and Remote Electronic Interface for TCS.

•Timing and Frequency Equipment (TFE)•Transmitter Control System (TCS) for the new SSX Transmitter
