Quality Check
The Quality check is a special mode of RINEXCLI activated with -Q
.
This mode is primarilary developed to act as a replacement of the QC mode of TEQC
,
which is the most commonly used feature of TEQC.
QC is first developed for Observation files analysis, but this tool
will accept other RINEX files, for which it will compute basic statistical analysis.
QC is a well known procedure in data preprocessing.
There are a few differences people who are very familiar with teqc
must
take into account when using our command line interface.
We share similarities with teqc
which will prove convenient
to advanced "teqc" users. Among them:
- Quick GNSS filters (
-G
,-R
, ...) still exist - Similar position analysis and reporting
- Similar signals analysis and reporting
Unlike teqc we are not limited to RINEX V2, V3 and V4 Observations are fully supported.
We do not support BINEX input data/files as of today.
We do not report an average receiver position (code based positioning), which serves as a "sampling context" sanity indicator. We consider we have enough markers of the sampling quality, and we also have an opmode dedicated to positioning, which is easy enough and quick to summon, for actual resolution.
We do not limit ourselves to the analysis of GPS and Glonass constellations.
We do not limit ourselves to L1/L2 analysis. This applies for instance to MP or DCB analyses.
Unlike teqc, we have no means to detect data duplicates, therefore such information is not reported.
We are limited to 1 ns precision which is significantly better than teqc. For example, in teqc the receiver clock drift is limited to 1ms/hour.
