The COSMIC radio occultation values of the ionospheric F2 region peak parameters are a potential source of ground-truth data for validation of global ionospheric models. They should therefore be validated against reliable ground-truth observations su

[1] Since their discovery in the 1970s, equatorial plasma bubbles (EPBs) have been invoked to explain the propagation of VHF signals on trans-equatorial circuits at night, and blamed for highly detrimental scintillation of VHF and GHz trans-ionospher

The Utah State University (USU) Gauss–Markov Kalman filter (GMKF) of the ionosphere uses the Ionosphere Forecast Model (IFM) to provide the background ionosphere, and a Kalman filter using Gauss–Markov relaxation to specify deviations from this b

The September 1999 Caribbean Ionospheric Campaign (CIC99), spanning the period 15–17 September 1999, was a period of repeated moderate geomagnetic storms. Both incoherent scatter radar (ISR) and digisonde F-layer measurements were made in the vicin

Digital down-conversion in software defined radios in space-to-Earth and Earth-to-space communications is challenging due to potentially large Doppler frequency offsets. The predictability of satellite orbits suggests that a computed Doppler offset c

Assimilation Ionosphere Model (AIM) is a physics-based, global, ionospheric specification model that is currently under development. It assimilates a diverse set of real-time (or near-real-time) measurements, such as ionograms, GPS slant total electr

We present measurements of currents, orbiter potentials, and plasma spectra during high-voltage arcing coincident with the tether break event on the Tethered Satellite System reflight. In addition to the unexpectedly high tether currents observed, pl

We will adopt the definition that low-earth-orbit (LEO) altitudes span the range 270 – 1000 km above the surface of the Earth. In this altitude region, free charges exist in the form of the ionospheric plasma. At its lower boundary the plasma densi
