Crate gnss_qc_traits 

GNSS Quality Control Traits

The Quality Control traits library (gnss-qc-traits) is a small library that offers the basic operations to form a geodesy processing pipeline, as used by our Quality Control library.

Existing Modules

• html: HTML report rendition
• merge: describes how we stack data into an already existing context
• processing: available on crate feature only, describes a filter designer and processing ops

Licensing

This library is part of the NAV-SLS framework which is licensed under Mozilla V2 Public license.

Macros

Structs

DecimationFilterprocessing

MaskFilterprocessing

Apply MaskFilters to focus on datasubsets you’re interested in.

TimeCorrectionprocessing

TimeCorrection allows precise Epoch translation to another TimeScale. For example, |TimeScale::GPST-TimeScale::UTC| when referencing TimeScale::GPST to TimeScale::UTC.

TimeCorrectionsDBprocessing

TimeCorrectionsDB is a TimeCorrections database used by TimeScale monitoring applications and applications that need exact TimeScale states at all times. Our Timeshift trait uses it in the precise conversion method. TimeCorrectionsDB has no means to “check” the internal content with respect to your application, other than the possible verification of the corrections validity (in time). You are responsible of the database content with respect to the current time and keeping it up to date. To avoid memory growth in long term applications, we propose:

Enums

DecimationErrorprocessing

Decimation filter parsing error

DecimationFilterTypeprocessing

Type of decimation filter

Filterprocessing

Preprocessing filters, to preprocess RINEX data prior further analysis. Filters can apply either on entire RINEX or subsets. Refer to [TargetItem] definition to understand which data subsets exist.

FilterItemprocessing

FilterItem represents items that filters or other GNSS processing ops may apply to.

MaskErrorprocessing

Mask filter parsing errors

MaskOperandprocessing

MaskOperand describes how to apply a given mask

MergeError

Merge specific Errors.

Repairprocessing

Repair

TimeCorrectionErrorprocessing

TimeCorrectionError returned by precise correction methods.

Traits

Decimateprocessing

The Decimate trait is implemented to reduce data rate prior analysis.

Maskingprocessing

Masking trait, to retain specific GNSS data subsets.
This can be used to retain specific signals or [Constellation]s.

Merge

Merge Trait is impleted to extend Data Contexts.

Preprocessingprocessing

Preprocessing Trait is usually implemented by GNSS data to preprocess prior further analysis.

QcHtmlReportinghtml

HTML reporting

RepairTraitprocessing

Splitprocessing

Implement Split to rearrange datasets timewise.

Timeshiftprocessing

The Timeshift trait allows transposition to different TimeScales and precise stirring.

Type Aliases

Markup

A block of markup is a string that does not need to be escaped.
