“…It is capable of simultaneously measuring the following observables using reflected (in vertical incidence) or refracted (in oblique incidence) signals from the ionosphere: frequency, range, amplitude, phase, Doppler shift and spread, angle of arrival, and wave polarization. Signal transmission is performed with two (NE‐SW and NW‐SE) crossed “delta” triple‐wired antennas of 40 m in height (Jodogne & Stankov, 2012; Sapundjiev et al., 2018) and reception is done with an array of four crossed magnetic dipole antennas in a standard triangular arrangement (LDI, 2014). DPS‐4D comes with the latest version of the computer program for automatic ionogram interpretation, the ARTIST‐5 (Galkin et al., 2008) and the software for Digisonde Drift Analysis (Kozlov & Paznukhov, 2008).…”

The performance of the digital ionospheric sounder at the mid‐latitude site of Dourbes, Belgium (4.6°E, 50.1°N) is evaluated and detailed here in terms of its capability to deliver ionograms of good quality at different sounding rates together with the quality of the automated scaling of ionospheric characteristics done by the dedicated computer software. The instrument is a Lowell Digisonde‐4D, also known as the Digital Portable Sounder 4D (DPS‐4D), equipped with the latest version 5 of the autoscaling software, Automatic Real‐Time Ionogram Scaler with True height. A thorough statistical analysis has been carried out of the automatic processing and scaling of the key ionospheric characteristics: critical frequencies, virtual heights, maximum usable frequency, and propagation factor. This analysis is based on the manually scaled hourly values of the above‐mentioned characteristics for the time period since the installation of the DPS‐4D in April 2011. Based on the analysis, the error bounds (with 95% probability) have been determined for each characteristic. Results are expected to be of particular interest to researchers, developers and users of the great variety of ionosphere/space weather monitoring services worldwide.
