What are the .sst files in Trimble baseline processing?

Hi Surveyors,

I'm trying to understand how, back in 2010, a previous surveyor processed the GNSS baselines using Trimble Geomatics Office (Version 1.63, Build 10) with the WAVE Baseline processor. He used a Trimble 4700 with a micro-centered L1/L2 antenna and a Trimble 5700 receiver with a Zephyr Geodetic antenna.

In addition to the .asc file and HTML reports, the baseline processing also generated two types of files saved in the / Baseline processing folder. These are .sst files—whose purpose I'm unsure of—and a wave.log file, which is an ASCII file viewable in Notepad.

Does anyone know what the .sst file is?

I appreciate any help,

Anita

I peeked into one of the old .sst files I have, and among the binary characters are ASCII references to the vector DAT files, the WAVE version, the station names, and NGS (antenna model used?).  So it appears to contain vector information and metadata.

Spot on, .SSF (Standard Storage Format) files are actually a package of other files, for example lots of individual files collected in a receiver that are bundled up on transfer.  

Most recently this format was the staple in the Trimble GIS world and the standard and only output from TerraSync for post processing in Pathfinder Office (PFO).

.SSF can still be processed in TBC.

But are *.sst files the same as *.ssf files?

Oops, no. Sorry I should have read more carefully.

The only bit I can add is that looking at my archives the .sst appears to be the binary record of individual TGO Wave processing sessions. 

If Wave reprocessed, for example against a different base file or settings, it added a new .sst into the folder, and an associated Ascii wave.log.

The wave.log got overwritten each time so there was only ever a "last one" which ultimately matched the timestamp of, and the particular file names that were readable in, only the final .sst.
