WAAS Update

WAAS (Wide Area Augmentation System) is a signal that most Trimble mapping units can use. This will increase the accuracy in the field (or in “real-time”) of your unit. In some cases, it can turn a 10 meter position to submeter. WAAS White Paper

WAAS is used mostly to enhance navigation capabilities. It should not be used as the primary mode of high-accuracy GPS data collection. Even with the two new satellites, there will be some places where WAAS is not available and post-processing is recommended. Post Processing White Paper

On July 16th, 2007 the FAA will be turning off the two legacy WAAS satellites in favor of two new ones. While this will help the coverage of WAAS in North America, it will require most Trimble mapping devices to be updated to accommodate the new satellites. Without these updates, most devices will stop tracking WAAS entirely since they are going to be looking for older satellites that are no longer broadcasting signals.

WAAS Update for all Trimble Receivers

Update procedures:
If you have a Geo handheld, you will need to identify if you have a Geo2003 or Geo2005.

Geo2003 models look like this:
Geo 2005 models look like this:

 

Geo 2003 procedure:

Please follow the procedure outlined in this document:  Geo2003 GPS Firmware Upgrades

Geo 2005 procedure:

Please follow the procedure outlined in this document:  Geo2005 GPS Firmware Upgrades

ProXT/XH Procedure:

  • Step 1: Follow the procedure outlined in this document:  ProXT/ProXH GPS Firmware Upgrades
  • Step 2: Right-click on this link and save target to your desktop or a folder that you can locate later: SBAS.ini
  • Step 3: Make sure that you have your field software installed on your unit (Terrasync, ArcPad/GPSCorrect, etc.)
  • Step 4: If you are using a Windows Mobile/CE data collector, ensure that you have Microsoft ActiveSync installed on your PC and are at version 4.5 If not, uninstall any older version and download the program here: ActiveSync v4.5 download. Plug the data collector into your computer’s USB port and establish an ActiveSync connection and hit “cancel” when the synchronization window comes up. This will establish a “guest” connection.
  • Step 5: On your PC, navigate to My Computer/Mobile Device/My Windows Mobile-Based Device/Program Files/Common Files/Trimble. Place the updated SBAS.ini file downloaded in Step #5 into the “Config” folder. Accept the message to overwrite the existing SBAS.ini file. You will now be able to track the new WAAS satellites. Only if you are using a laptop or pen-tablet as a data collector and are using Terrasync or GPSCorrect, copy the SBAS.ini to C:\Program Files\Common Files\Trimble\Config. If you are using GPS Analyst version 2.x as your field software, copy the SBAS.ini to C:\Program Files\Trimble\GPS Analyst\Bin. Accept the message to overwrite the existing SBAS.ini file. You will now be able to track the new WAAS satellites.

Pathfinder XB / Pathfinder XC / Juno ST procedure



The Pathfinder XB and Juno ST already track the new WAAS satellites without modification. The Pathfinder XC is not designed to track WAAS satellites.

Pathfinder XR/XRS procedure:

Note:  ProXR/XRS receivers with part number 29654-xx or 33302-xx will not support the new WAAS satellites. Therefore, these older receivers will not be able to track WAAS satellites after July 16th, 2007.

  • Step 1: Follow the procedure outlined in this document:  ProXRS GPS Firmware Upgrades
  • Step 2: Right-click on this link and save target to your desktop or a folder that you can locate later: SBAS.ini
  • Step 3: Make sure that you have your field software installed on your unit (Terrasync, ArcPad/GPSCorrect, etc.)
  • Step 4: If you are using a Windows Mobile/CE data collector, ensure that you have Microsoft ActiveSync installed on your PC and are at version 4.5 If not, uninstall any older version and download the program here: ActiveSync v4.5 download. Plug the data collector into your computer’s USB port and establish an ActiveSync connection and hit “cancel” when the synchronization window comes up. This will establish a “guest” connection.

Only if you are using a laptop or pen-tablet as a data collector and are using Terrasync or GPSCorrect, copy the SBAS.ini to C:\Program Files\Common Files\Trimble\Config. If you are using GPS Analyst version 2.x as your field software, copy the SBAS.ini to C:\Program Files\Trimble\GPS Analyst\Bin. Accept the message to overwrite the existing SBAS.ini file. You will now be able to track the new WAAS satellites.
