Sidereon.GNSS.StaticPositioning.Solution (Sidereon v3.0.0)

Multi-epoch static receiver solution.

position is the shared ITRF/IGS ECEF receiver position in metres. per_epoch_clock contains the fitted receiver clock for each epoch and constellation. covariance contains the full stacked state covariance plus ECEF and ENU position covariance blocks. Influence and residual fields are index-aligned to the input epochs and used measurements. rejected_sats lists, per epoch, each satellite left out with its Sidereon.GNSS.Positioning.Solution.rejection_reason/0; with the ionosphere requested, a satellite with no resolvable carrier (a GLONASS satellite with no channel or a channel outside -7..6) is reported as :ionosphere_carrier_unresolved and the rest of its epoch is solved.
