A modern, multi-GNSS alternative to TEQC
TEQC has been unmaintained since 2019 and lacks native RINEX 3/4 or modern constellation support. Run cloud-native multi-GNSS analysis with unified composite scoring.
Why engineers are replacing TEQC
TEQC was the gold standard for two decades, but was designed before modern multi-GNSS signals existed. In modern workflows, TEQC cannot process RINEX 3 or 4 files directly and ignores Galileo, BeiDou, and QZSS satellites. Converting files down to RINEX 2 drops new frequency bands and observation codes.
How POSFLOW Crux compares to TEQC
- Native RINEX 2.x, 3.x and 4.x support without format degradation
- Full multi-GNSS support: GPS, GLONASS, Galileo, BeiDou, QZSS
- Runs modern cloud QC engines across Fast, Flash, and Full analysis modes, plus legacy TEQC compatibility
- Zero local software installation, compilation or binary maintenance
- Automated navigation ephemeris download for satellite orbit geometry
- Composite 0–100 quality score with interactive visual charts and downloadable PDF reports
Supported quality metrics
Observation completeness (epoch and data level), cycle slip rates per 1000 epochs, multipath linear combinations (MP1, MP2, MP5), signal-to-noise ratio (SNR) distributions across all frequencies, and antenna/receiver header integrity.
Common questions
Can I still get classic TEQC format reports?
Yes. Crux includes legacy TEQC compatibility alongside modern multi-GNSS analysis modes, allowing you to generate traditional TEQC summaries or evaluate modern multi-frequency metrics.
Do I need to install command-line tools or Perl scripts locally?
No. All analysis engines run in POSFLOW cloud infrastructure. You only upload the observation file, and the platform handles ephemeris pairing, execution, and report normalization.
Is there a file size limit on the free tier?
The free tier supports files up to 100 MB per upload, including compressed .crx / .gz files, with 5 Fast Mode analyses per month.
