Sensing the ionosphere with the Spire radio occultation constellation
Journal of Space Weather and Space Climate, 2021 Radio occultation (RO) provides a cost-effective component of the overall sensor mix required to characterise the ionosphere over wide areas and in areas where it is not possible to deploy ground sensors. The paper describes the RO constellation that has

Radio occultation techniques for probing the ionosphere
Annals of Geophysics, 2004 GPS radio occultation measurements establish the basis for a new remote sensing technique for vertical profile information on the electron density of the entire ionosphere from satellite orbit heights down to the bottomside. No other profiling technique such as vertical sounding or incoherent scatter, unifies vertical profiling through the entire ...

Real-Time Tomographic Inversion of Truncated Ionospheric GNSS Radio Occultations
Remote Sensing, 2023 This paper presents a new way of combining Abel inversion and the Chapman model with a linearly increasing scale height to retrieve ionospheric electron density vertical profiles from truncated-sounding radio-occultation data. A linear Vary–Chap model is
