Module quality

Expand description

Measurement-quality control for GNSS positioning.

This module owns the language-independent RAIM/FDE decision logic and the standard pseudorange weighting primitives used by Sidereon’ QC surface.

Modules§

normality: Residual-distribution diagnostics: sample moments and normality tests.

FdeOptions: Options for fde.
FdeResult: Result of a fault-detection-and-exclusion loop.
FdeSppOptions: Options for fde_spp: the RAIM-gated exclusion loop plus the per-iteration solution-validation gates applied to each candidate solve.
PseudorangeVarianceOptions: Options for pseudorange_variance.
RaimInput: Minimal solution view needed by RAIM.
RaimOptions: Options for raim.
RaimResult: Result of a residual chi-square RAIM test.
RangeChiSquareTest: Global chi-square consistency test over a protected measurement set.
RangeFdeOptions: Options for raim_fde_design.
RangeFdeResult: Result of raim_fde_design.
RangeFdeRow: One linearized range measurement for raim_fde_design.
RangeMeasurementDiagnostic: Per-measurement diagnostics, in the caller’s input order.
ResidualDiagnostics: Standalone post-fit residual diagnostics.
SolutionValidationOptions: Validation policy for receiver solutions returned by SPP.
WeightEntry: One satellite/elevation entry used to build sigma or weight maps.

FdeError: Error from fde.
FdeSppError: Per-iteration failure carried out of the fde_spp solve closure: either the SPP solve failed for the current observation set, or the converged candidate failed validate_receiver_solution.
PseudorangeVarianceModel: Pseudorange variance model.
QualityError: Error from quality-control primitives.
RaimWeights: RAIM weighting mode.
SolutionValidationError: Error from validate_receiver_solution.

DEFAULT_P_FA: Default false-alarm probability for RAIM.
DEFAULT_VARIANCE_A_M: Default zenith-floor term for pseudorange variance, meters.
DEFAULT_VARIANCE_B_M: Default elevation-scaled term for pseudorange variance, meters.

chi2_inv: Chi-square inverse CDF.
fde: Fault detection and exclusion over a caller-supplied SPP solver.
fde_spp: Run single-point positioning with RAIM fault detection and exclusion.
pseudorange_variance: Pseudorange measurement variance, square meters.
raim: Residual-based chi-square RAIM.
raim_fde_design: Standalone, composable range RAIM/FDE over a generic linearized measurement set, independent of any full positioning solve.
raim_for_solution: Run RAIM over a generic solution.
residual_diagnostics: Post-fit residual diagnostics from residuals and optional inverse-variance weights.
sigmas: Build a satellite-to-sigma map. Entries whose variance cannot be computed are dropped, matching the Sidereon public API.
spp_robust_fde_driver: Run robust-reweighted SPP under the RAIM/FDE exclusion loop.
validate_receiver_solution: Apply the receiver-solution plausibility gates used by the Sidereon SPP API.
weight_vector: Build a satellite-to-inverse-variance-weight map. Entries whose variance cannot be computed are dropped, matching the Sidereon public API.
