Status on the New WAAS Satellites
•WAAS satellite PRN 135 (PanAmSat, 133 deg W) is now broadcasting WAAS corrections and can be used by
 some Trimble GPS receivers. See Suppport GPS receivers for more details.
•The second new WAAS satellite, PRN 138 (Telesat, 107.3 deg W), is still undergoing testing. The following
 information is from the FAA status document:
   - The service from PRN 138 is still undergoing testing and has not been certified. It is not yet being operating to
     FAA standard.
   - Unplanned outages may occur at any time.
   - The schedule information may change without notice.
   - The signals will be left on overnight and during weekends but if there is a failure, repairs will not be done until the
     next normal working shift.

Trimble will release a 'Support Bulletin' when WAAS satellite PRN 138 has been approved by the FAA to confirm that correction from this satellite are suitable for use with Trimble Mapping & GIS GPS receivers.

Supported GPS Receivers
The following GPS receivers support the new WAAS satellites:
• The GPS Pathfinder® XB receiver supports both new WAAS satellites with existing firmware. No additional firmware
  or software updates are required.
NOTE: The GPS Pathfinder XB receiver only operates on 'Auto' mode. You can not configure the receiver to track a particular satellite, or prevent it from tracking a SBAS satellite such as a WAAS PRN 138.
• The following receivers require you to install the new SBAS.ini file before they can use WAAS PRN 135:
   - GeoExplorer® 2005 series handhelds (GeoXM™, GeoXT™, GeoXH™ handhelds)
   - GPS Pathfinder Pro series receivers (ProXH™ and ProXT™ receivers)
NOTE: Other Trimble GPS receivers and GPS handhelds require firmware and/or software changes to support the new WAAS satellites.

New SBAS.ini File
A new SBAS.ini file is available for use with the GeoExplorer 2005 series handhelds and the GPS Pathfinder ProXH
and ProXT receivers. The new SBAS.ini file contains information on both new WAAS satellite (PRN 135 and PRN
138).
NOTE: Trimble recommends that you do not use PRN 138 until it is placed into 'Normal More' by the FAA. To prevent PRN 138 being tracked and used, configure the satellite to 'Disabled' in your Trimble field software.
To Install the new SBAS.ini file and configure your receiver to use the new WAAS satellite, download the new SBAS.ini file from the Trimble website. The file contains the new WAAS satellite information.

To do this, go to Support / Downloads area for the required Trimble Mapping & GIS receiver and software. For example, the TerraSync™ software, go to www.trimble.com and then click Support / TerraSync / Downloads.
