"RABSII – Radio Amateur Beacons aboard a nanoSatellite for the Investigation of the Ionosphere"

Verschillende leden binnen RST zijn betrokken bij het ontwerp van de payload en de testen in samenwerking met de universiteit van Delft.

Jurgen ON5ADL vormt samen met zijn collega's op de Faculty of Aerospace Engineering het projectleider team, waarbij Marc ON4ABS en Stijn ON4ILL de kern vormen rond de payload en Walter ON4AWM het antenne design.

Concept of Sporadic E Monitoring Using Space-Based Low Power Multiple Beacon-SystemsCurrent monitoring systems to detect sporadic E use ground-based setups, ionosondes, and the network of GNSS satellites in order to assess the phenomenon of sporadic E. This paper aims to monitor sporadic E using a miniature space-based platform in an atypical way. The setup consists of multiple radio-amateur beacon systems aboard satellites, each having a specific modulation and transmission scheme. This Radio Amateur Beacon System for the Investigation of the Ionosphere (RABSII) is coupled to a GNSS receiver, revealing the location of the platform. Multiple beacon data streams are sequentially sent from a satellite platform towards the Earth. By receiving and comparing the Signal-to-Noise ratios of these streams using a dedicated ground-based radio-amateur network of receiving stations, the presence of sporadic E can be determined, and a location-based model can be built. The advantage of this miniaturized, low-power, low-cost instrument is its ability to be put on any satellite platform in the future in order to map sporadic E.
