ITEM DESCRIPTION
Minimum
Elevation
Elevation refers to the angle at which a satellite appears in the sky (higher is better). The
Minimum Elevation setting is the minimum angle in the sky at which the lightbar will
acknowledge satellites. If you are having trouble receiving corrections, lower this setting.
Minimum
SNR
SNR (Signal to Noise Ratio) is a measure of the quality of a GPS signal. It is the ratio of useful
information received to noise. A high SNR value is better. If you are having trouble receiving
corrections, raise this setting.
Minimum
Satellites This is the minimum number of satellites required to provide GPS guidance and auto−steering.
If you are having trouble receiving corrections, lower this setting.
Maximum
HDOP
The Maximum HDOP (horizontal dilution of precision) is a measure of accuracy based on the
geometry of the satellites in the sky. If the satellites are near each other in the sky, the HDOP is
higher (lower is better). If you are having trouble receiving corrections, lower this setting.
Minimum Fix
Quality This is the minimum correction level required to provide GPS guidance and auto−steering. If
you are having trouble receiving corrections, lower this setting.
Configuring NMEA message output
NMEA (National Marine Electronics Association) messages are a standard format that enables GPS devices to
communicate.
Note: To access the NMEA messages that are output, you require the all−port cable (P/N 64045) or the serial
port add−on cable (P/N 63076).
The lightbar can output NMEA messages. This means that the lightbar can communicate with other devices, even
those created by other manufacturers, so long as the other device is also compatible with NMEA messages.
To configure NMEA output, select Configuration / System / GPS / NMEA Output.
