Digisonde measurement
 Kouba, Daniel ; Mošna, Zbyšek ; Koucká Knížová, Petra ; Boška, Josef ; Rejfek, Luboš
Ionospheric station in Průhonice currently performs its measurements using Digisonda DPS 4D. The vertical profile of the electron concentration can be measured by ionospheric vertical sounding using Ionosonde and Digisonde. The electron concentration profile shows the location of the layers of the ionosphere, the D, E, F1 and F2 layers, and the electron concentration at a given height. Another way to study the behavior of the ionosphere is to measure Doppler shift in ionospheric plasma. The Průhonická observatory is part of the Digisond World Network. The measured data is immediately automatically sent to the GIRO database (http://ulcar.uml.edu/DIDBase/).

Comparision of devices for monitoring of the ionosphere at the observatory Průhonice
 Beran, L. ; Chmelař, P. ; Rejfek, Luboš ; Chum, Jaroslav ; Mošna, Zbyšek
This document is about comparison of the methods ad systems for the measurement of the ionosphere used at the geophysical observatory Pruhonice (50N, 14.5E). Three systems for ionospheric monitoring are installed at the station. The first system for the monitoring of the ionosphere is Digisonde, the second system is countinuous Doppler sounding. Each system has its banefits and weaknesses which are compared in this paper.
