Outcomes

TRL9 achieved – LF & HF models validated in real conditions​

Robust hardware – IP65 enclosure, modular LF (~120 MHz) & HF (550–6000 MHz)​

Software v1.0.0 – user interface, automated calibration, real-time processing, advanced imaging, data streaming, encrypted updates​

20+ field trials – with UCLouvain, CRA-W, UGent & Osiris Agriculture​

First commercial sale – HF system delivered to RMA (Belgium, 2025)​

Market readiness – website launched, EUIPO trademark, 75-page user manual​

Outreach & visibility – invited keynote talks at two international conferences + live demo​

Challenges Faced

3D printing challenges - selection of optimal material & printer settings; resolved with PolyMax Tough PETG​

Temperature sensitivity - radar calibration instability solved with temperature-dependent calibration model​

Component sourcing & variability - discontinued battery module and inconsistent performance across components required small redesigns​

Drone downtime - Tundra drone maintenance interrupted field campaigns; period used for hardware development​

Impact (Socio-economic & Environmental)

Socio-economic & humanitarian value​

Food security & farmer resilience - higher yields with fewer resources​

Capacity building - empowers farmers, researchers & students with advanced tools​

Humanitarian impact - supports demining & land recovery for safe reuse​

Global relevance - aligned with Sustainable Development Goals 2 & 6, EU Green Deal & Soil Strategy​


Environmental impact​

Water-use efficiency - up to 30% reduction in water & energy needs (EU MIRAGE results)​

Climate resilience - real-time root-zone data for drought & heatwave adaptation​

Soil health preservation - non-invasive, reduces destructive sampling​

Reduced nutrient losses → lowers leaching, runoff & agrochemical pollution​
