D-GPS Set Up
The

function provides the ability to set up an external
Differential GPS, either automatically (default) or by manually retuning it to
a different differential beacon.
In
AUTO
mode, the D-GPS is set to automatic and beacon selection is made
automatically by the beacon receiver. The beacon frequency and bit rate
received from the beacon receiver are displayed. The soft keys are disabled
and grayed out.
In
MAN
ual mode, you can select the beacon frequency and bit rate that are sent
to the beacon receiver.
When you select
D-GPS SETUP
a pop-up window, providing the following
parameters, is displayed with associated soft keys:
•
Beacon ID - This shows the Beacon ID of the beacon transmitter. If no bea-
con has been found this item states
NOT LOCKED
.
•
Beacon Frequency - Both the menu item and associated soft keys show the
currently used differential beacon’s frequency in kHz. The frequency
range available is 283.5kHz to 325.0kHz.
•
Bit Rate - Both the menu item and associated soft keys show the currently
used differential beacon’s bit rate in bps. The rates available are 50bps,
100bps and 200bps.
•
Signal Strength and Signal to Noise Ratio - These items indicate the
received signal strength and Signal to Noise Ratio (SNR) in dB, received
from the beacon receiver. If the display unit is using RTCM data received
via NMEA, this information is not available and the item shows dashes,
one per character. The received Signal Strength and SNR are interrelated.
SNR provides a measure of the quality of the received signal and is depen-
dent upon signal strength.
•
Differential Age - This indicates the time elapsed since the last differential
beacon correction update.
