Position Sensors Sub-State Displays
The position sensor screens display information about each Loran and
GPS sensor included in the system.
Loran Information
The display below shows data for Loran 1, and a similar screen is
displayed for each Loran sensor. Also, each Loran sensor tracks two
GRIs, and turning the Large knob displays data for the other GRI. The
top line in this example shows the position sensor is Loran number 1,
and GRI number 1 is 9940. The middle line shows the GRI coverage
name and the bottom line shows the grade and GRI selection process.
"Auto" means the GRI selection process is automatic. "93" describes
the grade (relative usefulness) of the signals (from 0 to 99). The higher
the grade, the more useful the data.
No Data Available
If the NMC is not receiving data from Loran 1, the display below
appears.
Master Station Information
The display below shows Master station signal information. A similar
display appears for each GRI tracked by each Loran sensor. The top
line displays the Loran sensor number, GRI number, and GRI
identifier. The middle line shows the station and tracking status. In this
example, the Master station tracking status is "cycle." Tracking status
may be either :
"srch" - the station is in search.
