pub fn estimate_tec(
epochs: &[TecEpoch],
config: TecConfig,
) -> Result<TecEstimate, TecError>Expand description
Estimate TEC over a time-ordered stream of dual-frequency epochs.
Observations are grouped into continuous arcs by (satellite_id, ambiguity_id). Each arc must contain at least two samples, then code and
phase slant TEC are leveled, mapped to vertical TEC, and paired with a
thin-shell ionospheric pierce point for every sample.
