Error from solve.

Variants

InvalidInput

A public SPP input was malformed, non-finite, or outside its physical domain. Boundary validation rejects this before satellite selection or least-squares evaluation.

Fields

field: &'static str

The invalid input field.

kind: SppInputErrorKind

The validation failure category.

TooFewSatellites

Fewer usable satellites survived rejection than the solve has parameters (3 + n_systems: three position components plus one receiver clock per GNSS), so the solve is underdetermined.

Fields

used: usize

The number of satellites that survived rejection.

required: usize

The number of satellites required (3 + n_systems).

Singular(SolveError)

The trust-region step hit a rank-deficient Jacobian (degenerate geometry).

DuplicateObservation

The same satellite appears in more than one observation. One pseudorange per satellite is required, so the input is rejected rather than silently picking one (which would make the result depend on observation order).

Fields

satellite: GnssSatelliteId

The satellite that was observed more than once.

EphemerisLost

A satellite that survived the frozen selection had no usable SP3 position/clock at a transmit epoch reached during the solve. Returned instead of panicking; normally precluded by the selection step.

Fields

satellite: GnssSatelliteId

The satellite whose ephemeris became unavailable during the solve.

IonosphereUnsupported

The ionosphere correction was requested but an observed satellite has no resolvable carrier frequency, so the L1 Klobuchar delay cannot be scaled to it. GPS L1, Galileo E1, and BeiDou B1I have fixed carriers; a GLONASS satellite resolves its per-satellite FDMA carrier from SolveInputs::glonass_channels, so a GLONASS observation whose channel is absent from that map – or present but outside the valid FDMA range [-7, +6] – (rather than GLONASS as a whole) is rejected here rather than corrected with an undefined or out-of-domain frequency.

Fields

satellite: GnssSatelliteId

The satellite the ionosphere model does not cover.
