Since the ionosphere is a dispersive medium, the magnitudes of GNSS signal carrier phase delays and bend-ing angles are related to their frequency. The first-order iono-spheric effect can be largely mitigated by a dual-frequency linear combination of GPS signal observations. The resid-ual ionospheric errors in GNSS RO retrievals ...
