New Digisonde for research and monitoring applications
Radio Science, 2009The new Digisonde‐4D, while preserving the basic principles of the Digisonde family, introduces important hardware and software changes that implement the latest capabilities of new digital radio frequency (RF) circuitry and embedded computers. The “D” refers to digital transmitters and receivers in which no analog circuitry is used for conversion ...

Digisonde spreadFand GPS phase fluctuations in the equatorial ionosphere during solar maximum
Journal of Geophysical Research, 2006 The Jicamarca (11.95°S, 76.87°W) digisonde and the Arequipa (16.47°S, 71.49°W) GPS receiver observed the equatorial F region irregularities on the western South America from April 1999 to March 2000. The spread F measured by the digisonde were classified

Digisonde Drift Analysis Software
AIP Conference Proceedings, 2008This paper introduces a newly developed conceptual Java-based software package for the digisonde drift data analysis and visualization. This package replaced the less versatile Fortran-based applications previously developed at UMLCAR. A dedicated database intended for raw and processed drift data storage, access, and exchange has also been established

Precise Radar Range Measurements with Digisondes
AIP Conference Proceedings, 2008A digisonde phase-difference technique measures precise radar ranges of echoes reflected from the ionosphere. The technique, which analyzes the phase differences between signals at slightly different frequencies, allows measuring the reflection range, i.e., the virtual height h′(f) for vertical sounding, with accuracies of better than one kilometer ...

First results from the Cyprus digisonde
IET 11th International Conference on Ionospheric Radio Systems and Techniques (IRST 2009), 2009A new ionospheric station was recently established in Nicosia (Cyprus) to initiate ionospheric research on the island. The deployment of a DPS-4D (digisonde) developed at the University of Massachusetts Lowell's Center for Atmospheric Research (UMLCAR), is considered very beneficial to the ionospheric scientific community, taking into account the lack ...
