Quadsat

Quadsat is a Danish company with headquarters, R&D, and production facilities located at the UAS Denmark Test Center—one of Europe’s leading drone test centers—at Hans Christian Andersen Airport in Odense.

Since its early start-up in 2017, Quadsat has been committed to redefining satellite antenna testing and calibration through drone-based technology, making it more accurate, accessible, and operationally efficient across the industry. The technology has evolved into a capability that directly supports modern defense Electronic Warfare (EW) operations, where control of the electromagnetic spectrum is essential.

Today, Quadsat delivers battle-proven and field-deployable Radio Frequency (RF) testing and spectrum intelligence solutions designed to support defense and communications forces in understanding, managing, and securing their spectral environment.

Quadsat’s systems provide precise insight into signal behavior, antenna performance, and overall RF readiness, allowing organizations to operate confidently in both congested and contested conditions in the field.

At the core of Quadsat’s offering is SpectraLoc, the company’s platform-agnostic Electronic Warfare payload, which—when paired with drones and specialized software—enables precise geolocation of radars, air defense systems and jamming devices - without being seen – which traditional systems cannot match. This operational agility strengthens the capacity to secure a country’s spectrum and protect its communication infrastructure across land, sea, and air. Quadsat helps defense organizations build resilience, reduce risk, and maintain superiority in an increasingly complex electromagnetic battlespace.
