Danish RF testing and electronic-warfare payload specialist based at the UAS Denmark Test Center in Odense. Quadsat’s SpectraLoc passive RF detection payload was successfully flight-integrated onboard Portuguese unicorn Tekever’s AR3 EVO tactical drone in Constância, Portugal, in March 2026 — one of the most concrete DK–PT defence-tech partnerships of the year.
Quadsat’s core business is drone-based satellite-antenna testing and RF spectrum intelligence, sold into defence and commercial satellite-communications operators. The company headquarters, R&D and production are co-located inside the UAS Denmark Test Center in Odense, part of the wider Odense Robotics cluster of around 150 robotics, automation and drone companies that together form Denmark’s leading autonomous-systems hub.
The Portuguese corridor link runs through SpectraLoc, Quadsat’s long-range passive RF detection payload. SpectraLoc is designed to detect, identify and geolocate hostile radar emitters without emitting any signal of its own — a defining capability for modern airborne SIGINT and counter-radar missions. In March 2026, Quadsat and Tekever announced the successful in-flight integration of SpectraLoc aboard Tekever’s AR3 EVO tactical fixed-wing drone, in flight trials conducted in Constância, Portugal. The payload was housed in a fairing under the AR3 EVO’s mid-fuselage, within the platform’s roughly 25 kg MTOW envelope. Both companies have publicly committed to continued refinement and operational testing of the integrated solution.
The Tekever-Quadsat work is the clearest single technical demonstration so far that the Portugal-Nordic defence corridor can produce integrated, flight-ready systems rather than only MoUs and joint position papers. With Sweden’s GUTE II layered air-defence programme and the broader Nordic build-out of SIGINT and counter-UAS capability driving 2025-2027 procurement, a Portuguese tactical drone carrying a Danish passive-RF payload is a credible bid for Nordic ISR and EW line items — one that neither company could put on the table alone.
