5. INITIAL SETTINGS
9
83 21 Error rate of connection data
Beacon signal status
Reference station status
DGPS signal strength
This value is between 1
and 84. The higher the
value, the stronger the
signal. If a noise appears
at reception band width,
the value becomes bigger.
This value is between 1 to 22. The higher
the value, the better the reception of
beacon signal. When this value is less
than 20, the error is included in the
correction data. In this time, position
fixing is done by using past position data.
When the ship is in the service area of a
beacon station, this value should be 21 or
22. If not, check as follows.
•
Check the grounding.
•
Check the radar beam interference.
•
Check the noise of power generator of
the ship.
Input/Output Setting
The GP-80 can output navigation information to external equipment. For example, it can
output position data to a radar or echo sounder for display on their display screen. You can
convert a Loran Plotter to a GPS Plotter with position data from the GP-80.
Before selecting data to output, confirm what data the external equipment requires. Output
necessary data only. Outputting unnecessary data can cause receiving problems at the
external equipment.
Talker
All data transmitted by marine electronics equipment is prefixed with a two character code
which tells external equipment what equipment is transmitting data. This two character code
is called the talker. The GP-80 contains the talkers GP, LC and DE.
Because GPS is a relatively new system some early model equipment do not recognize the
GP talker name. In this case transmit data using a conventional talker, one the equipment
recognizes, such as Loran C.
