NetClock/GTP Instruction Manual
SSSS
= Fix Mode; SEARCHING, 2D-FIX, 3D-FIX. Searching
is the typical mode when using the window mount
antenna.
2D-FIX is possible if the receiver is tracking at least
three qualified satellites. The receiver latitude and
longitude can be determined from a 2D-Fix.
3D-FIX is possible if the receiver is tracking at least
four qualified satellites. The receiver location and
elevation can be solved from a 3D-Fix.
##.#
= Dilution of precision; 00.0…99.9.
This value indicates the degree of uncertainty of a
Position Fix due to the geometry of the satellites used
in the solution. The lower the DOP value, except 00.0,
the lower the degree of uncertainty.
N
= North Latitude
S
= South Latitude
DDD MM SS.SSS
= Latitude Degrees:Minutes:Seconds
E
= East Longitude
W
= West Longitude
DD MM SS.SSS
= Longitude Degrees:Minutes:Seconds
HHHH.HH
= Height of GPS antenna expressed in meters. The
height solution is relative to the GPS reference
ellipsoid and not sea level.
QQQQQ
= Results of GPS qualification, Passed, Failed. The
GPS signal is considered qualified when at least one
satellite is received having a vehicle ID greater than 1
and is available for Position Fix usage.
NOTE: Position data contained in this response shall
be all zeroes until a 2D-Fix is acquired. Elevation data
is available when a 3D-Fix is acquired.
