An SBF file is a GPS data file created by Septentrio GNSS receivers, which are electronic devices that receive and process signals from global navigation satellite system (GNSS) satellites. It contains a data log about the GPS position, time, and velocity of a device fitted with a GNSS receiver. SBF files are saved in binary format to reduce file size.

Septentrio GNSS receivers are used in a large variety of industries, which include geographic information systems, scientific and unmanned aerial vehicles, marine, construction, agriculture, and survey and mapping. SBF files are used to store the data logs for devices used in these industries. SBF files may be opened by a variety of tools from the Septentrio RxTools suite, which include "SBF Analyzer" and "SBF Converter". You can convert SBF files using the "SBF Converter" to several formats, such as ASCII, KML, GPX, and RINEX. The tools can be found in the rools\binary\win32 subdirectory in the installation path.
