In the event that you are using a Loran-C Navigator for the first time, please
refer to the Raynav 508/508~ Loran-C Sensor instruction manual for basic
loran information. The Introduction section of the 508 manual includes a
listing of common Loran C Terminology used with loran.
If your
NAV398
is using the

GPS Sensor, the Raystar 108
instruction manual includes a general description of the GPS system which
may also be helpful. The

Receiver to your system, a simple explanation of the US Coast Guard’s
DGPS system is included in that manual for your reference.
