"GPS Longitude"
Placement label: GPS Longitude
The "GPS Longitude" window reports the vehicle's real-
time position in angular distance expressed in degrees on
a circle of reference from the zero meridian.
"GPS PDOP"
Placement label: GPS PDOP
The "GPS PDOP" window reports GPS signal quality
at the vehicle location. Position Dilution Of Precision
(PDOP) offers the best overview since it reflects the
geometry of the satellites above the vehicle. A low PDOP
means that the positioning of satellites is good and that
good positional accuracy can be expected. In general,
any value below 2 offers good working results.
"DGPS SNR"
Placement label: DGPS SNR
The "DGPS SNR" window reports Signal-to-Noise Ratio
(SNR) at the vehicle's location. SNR is a measure of sig-
nal strength against electrical background noise. A higher
SNR number provides better accuracy. Nominal values
for the various technologies used are:
GPS
WAAS/EGNOS
OmniSTAR HP/XP/G2, VBS
