Native cloud conversion for Septentrio receivers
Septentrio receivers are industry standards for drone LiDAR, maritime surveying, autonomous vehicles, and scientific CORS stations. Flux provides native cloud ingestion for Septentrio Binary Format (.sbf), decoding all multi-frequency observations across GPS, GLONASS, Galileo, BeiDou, and QZSS without requiring desktop Septentrio RxTools.
Supported Septentrio hardware and features
- Full support for Mosaic-X5, Mosaic-CLAS, AsteRx-m3, AsteRx4, and PolarRx5 series
- Extracts multi-frequency carrier phase, pseudorange, Doppler, and SNR observables
- Export to standard RINEX 2.11, 3.04, 3.05, and 4.02 observation and navigation files
- Preserves high-rate kinematic data (up to 50 Hz or 100 Hz) for UAV PPK trajectories
- Direct integration with Crux for immediate quality score validation and multipath triage
- Optional Hatanaka (.crx) compression and gzip bundling for compact cloud archiving
Eliminate proprietary toolchain bottlenecks
Survey operations with mixed fleets often struggle with receiver-specific desktop software. With PosFlow Flux, Septentrio SBF files convert in the same unified cloud workflow alongside u-blox, Trimble, and Leica logs.
Common questions
Does it support multi-band observations from Mosaic-X5?
Yes. Flux fully decodes multi-frequency signals (L1, L2, L5, E1, E5a, E5b, E6, B1I, B1C, B2a, B2b, B3I) logged by Septentrio Mosaic-X5 and AsteRx-m3 modules.
Can I convert large drone flight logs recorded at high epoch rates?
Yes. High-frequency 10 Hz, 20 Hz, and 50 Hz kinematic logs from drone photogrammetry and aerial LiDAR surveys are processed smoothly.
Is SBF to RINEX conversion free?
Yes. The Free plan includes format conversion up to 100 MB per file with no credit card required.
What won't produce a result
Worth checking before you upload, so a run doesn't cost you credits to tell you what your data was missing.
A .sbf log recorded with only the position/navigation blocks enabled, not the raw measurement blocks
The receiver's raw measurement blocks turned on at logging time. Without them there is no carrier phase or pseudorange to write into RINEX, only a computed fix.
A file that has already been processed or re-saved by other software before upload
The original .sbf binary as the receiver wrote it. A re-saved copy can drop the block headers the converter uses to identify the log.
