Sidereon.GNSS.PrecisePositioning.FixedSolution (Sidereon v3.0.0)

Static multi-epoch integer-fixed carrier-phase solution.

Summary

Types

position()

residual()

t()

A static integer-fixed solution. epoch_clocks holds one clock per solved epoch, in the order of solved_epoch_indices, and ssr_bias_exclusions the observations left out for an unresolved SSR/HAS bias, which this binding never requests.
