GPS Station Tagging 3.2.5
The GPS Station Tagging function allows the operator control over the GPS operation
during measurements.
a) The GPS options that are supported in FlowTracker2 software are grouped under
the following,
i). Automatic . The automatic option for the GPS allows the FlowTracker2 to
perform GPS measurements at each station without any additional interaction
with the software.
•
The GPS receiver is Continuously Operating and receiving data from
satellites when the FlowTracker2 handheld is activated.
•
If a GPS lock is not obtained before the station measurement is completed,
the software will not record positional information for the station. The GPS
status Icons are listed in
Table 3:4
.
•
The positional information is averaged over the time a station is created to
improve the overall measurement accuracy. The software starts averaging
the positional information when the
Add Station function is selected and
stops when the station is completed, from where the averaged position is
recorded against the station. The averaging process is performed for both
Discharge and General modes.
•
When editing an existing station and Automatic GPS mode is selected, the
logic reverts to “Manual GPS” mode to ensure that a position is not
assigned while editing away from the actual station location.
The operator needs to ensure that the wading rod is placed in the correct position and
vertical before the “Add Station” function is selected. This will improve the overall
accuracy of the GPS measurement.
ii). Manual . The manual option provides the operator control over GPS
measurements and requires the operator to select “Record GPS Location”
function before velocity measurements are made at a station for both
Discharge and General modes.
•
The GPS receiver is on Cold Start and is NOT receiving data from satellites.
•
The manual GPS measurement option forms part of the “Add Station”
configuration screen and is located at the bottom of the screen. The
“Record GPS Location” function can be accessed by using the Bottom
Arrow.
