Code
: we are receiving a code differential solution (precision
is about 1 to 10 meters).
Float
: we are receiving a carrier phase differential solution
with float ambiguities (precision is typically within 0.1_m to
0.5_m).
Fixed
: we are receiving a carrier phase differential solution
with fixed ambiguities (precision is typically within 15_mm
for single-frequency receivers and 5_mm for dual-frequency
receivers).
H Precision
: displays the root mean squared (RMS) error of the
horizontal solution reported by the receiver. It is displayed in project
units.
V Precision
: displays the RMS error of the vertical solution reported
by the receiver. It is displayed in project units.
HDOP
: displays the Horizontal Dilution of Precision. It is a measure
of the geometrical quality of the solution. DOP has no units and
lower numbers indicate better solution geometry.
VDOP
: displays the Vertical Dilution of Precision. It is a measure of
the geometrical quality of the solution.
PDOP
: displays the Position Dilution of Precision. It is a combination
of HDOP, VDOP and Time Dilution of Precision. It will always be
larger than HDOP and VDOP.
Data Link
The Data Link card displays information about the radio
communications.
Receiver mode
: (see the Receiver Status card,
above.)
Radio Reception
: displays two values indicating
radio signal quality. This information is only
displayed if the receiver is in rover mode.
Signal
Latency
: displays the age of the
differential correction used in the current GPS
solution. This value should be one second or
less for good RTK solutions. If this value is
