GPS Equipment
Pathfinder ProXRS GPS Receiver
Trimble's GPS Pathfinder® ProXRS is a 12-channel GIS mapping system
that combines a high-performance GPS receiver and antenna with a MSK beacon
differential correction receiver for real-time mapping and navigating
capability. With the GPS Pathfinder ProXRS, operators can gather
sub-meter GPS data using real-time or post-processing differential
correction (depending on the availability of a base station, radio beacon,
or NAVSTAR satellite service). The ProXRS features a hand-held data
collector running Trimble's powerful Asset Surveyor® data collection
software.
The GPS Pathfinder® ProXRS also features Trimble's advanced
Everest™ technology, which eliminates positional error due to
multipath signals. Multipath signals - typically reflected off of walls,
water, vehicles, and other surfaces - can make it difficult to determine
accurate positions. Everest uses a patented technique to remove these
multipath signals before the measurements are used to calculate a final
position.
GeoExplorer 3
Trimble's GeoExplorer® 3 is the smallest, lightest GPS mapping tool
available - researchers can easily carry and operate the pocket-sized
product with one hand. As part of the GPS Pathfinder® series, the
GeoExplorer 3 provides the reliable, accurate GPS positioning found only in
Trimble GPS mapping systems. Trimble's
GPS Pathfinder® Office Software, which comes bundled with the system,
aids in data dictionary creation, data processing and GIS data export and
import.
The GeoExplorer 3 system allows the user to accomplish more in the field.
When coupled with Trimble's Beacon-on-a-Belt (BoB™) differential
receiver, the GeoExplorer 3 system enables the user to effectively relocate
existing features for data update by using the graphical navigation and map
displays. The GeoExplorer 3 can also be used with post-processing
differential GPS.
The GeoExplorer 3 tracks up to twelve satellites and provides 2-5 meter
accuracy after differential correction. Submeter accuracy can be achieved
by recording carrier phase data and using advanced processing software.
GeoExplorer XT
 Trimble®
GeoXT™ handheld, from the GeoExplorer® series, combines submeter GPS with
Microsoft® Windows Mobile™ 2003 software for Pocket PCs in one rugged unit. The
synergy between GPS and Windows Mobile software lets you concentrate on what's
important: collecting and maintaining high-quality data for your GIS. Plus
there's integrated Bluetooth®* for wireless connectivity to other
Bluetooth-enabled devices, such as a Trimble GeoBeacon™ receiver for real-time
corrections, and a cell phone for connection to the Internet.
The GeoXT runs
multiple applications and has a familiar user interface—all the advantages
you've come to expect from a GeoExplorer series handheld. In the field, the
high-performance GPS receiver gives you the best accuracy possible. For reliable
navigation back to assets, use it with SBAS corrections, or use Bluetooth to
connect to a GeoBeacon receiver. To get the most precise data for your GIS, use
TerraSync, Trimble GPScorrect™ extension for ESRI ArcPad software, or a GPS
Pathfinder® Tools application to collect SSF data files, and postprocess using
GPS Pathfinder Office software or the Trimble GPS Analyst™ extension for ESRI
ArcGIS software.
Pathfinder Office Software
Built on the solid foundation established by PFINDERtm, Pathfinder
Officetm software is the next generation of GPS data processing
software. It helps you in every phase of your work, from planning
to differential correction, data export, and map generation. Pathfinder
Office software is Microsoft Windowstm-based and is designed
for ease-of-use and high productivity. With the Batch Processor
you can automate your workflow - download data, differentially
correct, and export it to a GIS in a single step. The Data Dictionary
Editor allows you to create custom menus for uploading to your
data collector. For high accuracy applications, a carrier phase
processing module is included with Pathfinder Office software.
Pathfinder Office software makes exporting GPS data to your GIS
a simple process. Parameters for exporting data can be set up
in the system and saved for use on future projects. Pathfinder
Office will export files to most GIS and CAD systems including
ARC/INFO, AutoCAD, Intergraph MGE, MapInfo, GRASS and MOSS.
