5 Using the GNSS Receiver
76 GeoExplorer 6000 Series User Guide
Factors that affect real-time DGNSS accuracy include how often the corrections are
updated, how far you are from the base station, and whether the coordinate system
used by the correction source matches the coordinate system used by the GNSS
receiver.
Postprocessed DGNSS
In postprocessed DGNSS, the collected GNSS data is transferred to an office computer,
and measurements from the base station are downloaded. You can postprocess GNSS
data collected with Trimble GNSS field software using:
• the GPS Pathfinder Office software version 5.10 (with the latest updates) or later.
• the Trimble GPS Analyst
™
extension for Esri ArcGIS Desktop software version
2.40 (with the latest updates) or later.
Typically, postprocessed DGNSS uses only one base station. However, when
differentially correcting data collected with GeoXH receivers using H-Star technology,
you can select multiple base stations to correct the file against for improved accuracy.
Factors that affect the accuracy of postprocessed DGNSS include the type of receiver
and antenna used at the base station, the distance between the base station and the
location where the rover data was collected, the accuracy of the base station position,
and the logging interval at the base station.
For more information, refer to the documentation provided with the postprocessing
software.
Postprocessed real-time DGNSS
If you collected data with 10 cm accuracy in real time, you do not need to postprocess
the data.
However, if your data files contain autonomous (uncorrected) positions as well as
real-time corrected positions, Trimble recommends that you postprocess the data.
During postprocessing, you can choose whether to correct only autonomous positions,
or all positions.
If you collected data with submeter accuracy in real time, Trimble recommends that
you postprocess the data, as postprocessed data is usually more accurate than data
corrected in real time.
Outputting NMEA data to external equipment
Use the GNSS Connector software to specify how the integrated GNSS receiver
communicates with equipment that is connected to one of the handheld’s external
communications ports.
Note – You must first install the GNSS Connector software. See GNSS Connector software,
page 63 for details.
To open GNSS Connector, tap / GNSS Connector.
