The issues seen last week of NGS CORS Base files unsuccessfully downloading directly using the System Defined base provider list in Trimble GPS Pathfinder Office’s Differential Correction Wizard and in the Trimble Positions Desktop add-in’s Processing Profiles has been resolved. Base data should be available from all NGS Base stations during the time frame you received this error message.
We’ve extensively tested this using a few NGS CORS stations this morning. Base files were successfully downloaded through the Trimble GPS Pathfinder Office Differential Correction Wizard using the System Defined list. All files processed as normal.
Original error message:
