Structs

Corrections

Which correction terms a solve applies, building up incrementally.

Dop

The dilution-of-precision scalars for a geometry.

GalileoNequickCoeffs

Galileo broadcast NeQuick-G ionosphere coefficients (ai0, ai1, ai2).

KlobucharCoeffs

Broadcast Klobuchar coefficients for the ionosphere term.

LineOfSight

A line-of-sight unit vector from the receiver toward a satellite, in ECEF.

Observation

A single GPS L1 pseudorange observation.

ReceiverSolution

A receiver position/clock solution with its geometry diagnostics.

RejectedSat

A rejected satellite paired with its rejection reason.

RobustConfig

Opt-in Huber/IRLS robust-reweighting configuration.

SolutionMetadata

Models and convergence detail describing how a solution was produced.

SolveInputs

Everything one SPP solve needs besides the SP3 product itself.

SolvePolicy

Language-independent SPP solve policy used by the public API boundary.

SourcedSolution

A receiver solution paired with the provenance of the ephemeris that produced it.

SurfaceMet

Surface meteorology for the troposphere term.

Enums

BroadcastReason

Why solve_with_fallback produced a fix from broadcast ephemeris.

DopError

Why a geometry has no finite DOP.

FallbackError

Error from solve_with_fallback, tagged with which path failed.

FixSource

Which ephemeris source produced a SourcedSolution, with its provenance.

RejectionReason

Why a satellite was excluded from the solve, in pinned priority order.

SolvePolicyError

Error from solve_with_policy.

SppError

Error from solve.

Constants

DEFAULT_ROBUST_MAX_OUTER

Default maximum outer IRLS reweighting iterations (the warm-started static solve at iteration 0 plus reweighted resolves up to this many total).

DEFAULT_ROBUST_OUTER_TOL_M

Default outer-loop position step tolerance (m): the outer IRLS loop stops when the L2 norm of the position change between successive reweighted solves drops below this.

DEFAULT_ROBUST_SCALE_FLOOR_M

Default robust scale floor (m): the smallest MAD-derived scale allowed, so a near-perfect fit cannot blow up the scaled residuals and down-weight every satellite. Sized to the metre-class code noise of cheap single-frequency receivers.

ELEVATION_MASK_RAD

Elevation mask in radians (10 degrees); a satellite is excluded iff its elevation is strictly below this value.

SIGMA0_M

Base measurement standard deviation (m) for the elevation weight model.

Traits

EphemerisSource

A source of satellite position and clock at a transmit epoch.

Functions

dop

Compute the DOP scalars from line-of-sight directions, diagonal weights, and the receiver geodetic position.

residual_rms

Root-mean-square of post-fit pseudorange residuals (0.0 when empty).

solve

Run the SPP solve from synthesized/measured pseudoranges.

solve_broadcast

Solve a receiver position from broadcast ephemeris ALONE: the supported real-time / offline single-point-positioning mode.

solve_spp_batch_parallel

Solve a batch of independent SPP epochs against a shared ephemeris, fanning the independent per-epoch solves across a rayon thread pool.

solve_spp_batch_serial

Solve a batch of independent SPP epochs against a shared ephemeris, serially.

solve_with_fallback

Solve a receiver position, preferring precise products and falling back to broadcast ephemeris, reporting which source was used and how stale it is.

solve_with_policy

Run SPP under the public API’s language-independent validation/orchestration policy.

solve_with_solver

SPP solve with an explicit SolverRecipe for the trust-region stage.

Type Aliases

Error

Error type returned by solve.

Solution

Role-oriented alias for a solved receiver state.
