Module carrier_phase 

Carrier-phase combinations, cycle-slip detection, and Hatch smoothing.

This module owns the language-independent modeling behind Sidereon’ CarrierPhase API: phase-cycle conversion, geometry-free and Melbourne-Wubbena combinations, loss-of-lock/GF/MW/data-gap cycle-slip classification, and single/dual-frequency Hatch smoothing.
