Using accuracy-based logging
If you are using the TerraSync software, use accuracy-based logging to ensure that only
GPS positions that meet the specified estimated accuracy are logged. GPS positions
that do not meet your accuracy requirements are not logged.
Note – Accuracy estimates for streaming (dynamic) GPS positions may not be as good as
those for static GPS positions.
To configure accuracy-based logging in the TerraSync software:
1. In the Setup section of the TerraSync software, tap
Logging Settings. The Logging Settings form
appears.
2. Tap the
Setup button below the Accuracy
Settings field. The Accuracy Settings form appears.
3. In the Accuracy Value For Display/Logging fields,
select the parameters that will be used to
determine the estimated accuracy:
– Select whether to use the horizontal or
vertical accuracy of the current GPS position.
– Select In the field to use the current
estimated accuracy (recommended if you are
using a real-time correction source), or select Postprocessed to use the
predicted estimated accuracy that will be achieved after the field data has
been postprocessed.
4. If you selected Postprocessed, select the estimated distance to the base station
that will be used for postprocessing from the Postprocessing Base Distance field.
If you will use more than one base station (during H-Star processing), specify
the estimated distance to the closest base station.
5. Set the Use Accuracy-based Logging field to Yes. The settings fields for
accuracy-based logging appear.
6. In the Apply Accuracy-based Logging To field, select the feature types that you
want to log only if the GPS positions meet your required accuracy.
7. In the Required Accuracy field, select the estimated accuracy that is required
before GPS positions are logged.
8. Tap
OK.
Note – Accuracy settings do not affect GPS positions that are used for navigation. GPS
positions are still calculated by the GPS receiver and are available for navigation.
