Using SBAS corrections
The GeoExplorer 2005 series handheld has an integrated receiver
that uses Satellite Based Augmentation Systems (SBAS) correction
messages to improve the accuracy and integrity of GPS data.
The receiver tracks SBAS satellites according to their geographical
location:
• Wide Area Augmentation System (WAAS) satellites between
40° W and 180° W, and between 10° N and 90° N.
• European Geostationary Navigation Overlay Service (EGNOS)
satellites between 40° W and 60° E, and between 10° N and 90° N.
• MTSAT Satellite-based Augmentation System (MSAS) satellites
between 120° E and 165° E.
You can use the default zones, or configure the receiver to use
particular SBAS satellites in the Integrated SBAS Settings form.
To use SBAS corrections:
1. In the GPS Controller software,
open the Real-time section and tap
the
Setup button .
2. In the Choice 1 field, select
Integrated SBAS. To select
particular satellites, tap the
Setup
button next to the Choice 1 field.
3. In the Choice 2 field, specify
whether to use uncorrected
positions, or to stop using GPS
positions, if corrections are not
available.
4. Tap
OK.
Note – If TerraSync software or the GPScorrect extension for ArcPad is
installed, configure real-time settings in that application instead of the
GPS Controller software.
