Oscillator Information
The display below shows the OSC (Reference Oscillator) frequency
and temperature. The OSC is used in timing the station TDs. In this
example, the OSC frequency is 8.000101 MHz and is at 24
o
C.
LORAN1 GRI1 9940
OSC 8.00010MHz
temp 24°C
SYS
Each Loran sensor tracks two GRI’s simultaneously, and can use
stations from both GRIs to calculate a Latitude/Longitude position.
Stations In Use
The display below shows multi-chain information, and whether
manual or automatic triad selection is in use. The display also shows
the stations used to calculate position, and whether the stations are
selected manually or automatically.

GPS Status
The screen below displays information concerning a GPS (Global
Positioning System) Sensor. The top line shows the GPS number and
whether the position is 2D or 3D (2-Dimensional or 3-Dimensional).
If the position is 2D, altitude is not calculated; if the position is 3D, the
sensor is calculating both position and altitude. If “NO” is displayed,
the system has not calculated a position. The middle line shows the
number of healthy satellites in the GPS system. The bottom line shows
the number of visible satellites. In this example, the GPS sensor has
calculated a 2D position , with 22 healthy satellites and 8 satellites
visible.
