The Athens Digisonde is an infrastructure for remote sensing of the Earth’s Ionosphere, operated by NOA in Penteli since September 2000. The Digisonde is a Digital Portable Sounder with four receiving antennas (DPS-4), spaced about one wavelength apart. Data are collected and retrieved in real time (24/7 operation) and are openly available through the main portal of the Ionospheric Group of IAASARS/NOA. The Athens Digisonde is part of the following international networks: GIRO, ESPAS, WDC for Solar-Terrestrial Physics (RAL) and IPS/WDC. The Athens Digisonde participates systematically in cal/val campaigns for LEO satellites.
