Open SSF File

SSF extension files have various formats that they can adopt, some of them below

Trimble GIS

In this particular case, an SSF extension file is a data file used by Trimble GIS mapping software applications, which are used with GPS devices to collect field data.

More about Trimble GIS

Trimble GPS software is an easy-to-use, feature-rich GNSS field data post-processing software suite designed to develop GIS information that is consistent, reliable, and accurate.

The SSF file contains GPS position data recorded from a Trimble device.

SSF files are used to record GPS data and create custom coordinate systems for the user.

SSF files can be differentially post-processed to improve the accuracy of recorded positions, through the use of Trimble GIS Pathfinder Office.

Fixed SSF files use the COR file extension.

Structured Subtitle Format File

In this second case, the SSF extension file is used as a movie subtitle file created in the Structured Subtitle Format, that's where the acronym comes from.

This SSF file uses verbose CSS syntax, unlike the plain text notation of other popular plain text formats, and is therefore more difficult to manually edit with a text editor.

Due to its complexity, the SSF format has not been widely adopted.
