QuadSAT (Denmark) – Drone-Based Satellite Antenna Testing & Calibration

QuadSAT is a Danish deep-tech company that has transformed a niche yet critical aspect of the space and defense industry: the testing and calibration of satellite communication antennas using drones. Founded in 2017 in Denmark, QuadSAT emerged from the recognition that conventional methods of antenna validation were cumbersome and costly, often requiring dedicated infrastructure or live satellites. By contrast, QuadSAT’s approach uses unmanned aerial vehicles (UAVs) equipped with specialized radio-frequency (RF) payloads to emulate satellites and conduct precise measurements[1][2]. This innovative solution has attracted attention across the satellite communications (SATCOM) sector and defense community, positioning QuadSAT as a pioneer in mobile, on-site RF testing. In an era where secure and reliable connectivity underpins both civilian networks and military operations, QuadSAT’s technology addresses a strategic need. The company’s journey – from an idea conceived by its founders during university studies to partnerships with European space agencies and NATO – offers insight into how European startups can bolster technological sovereignty. As QuadSAT expands its capabilities from commercial SATCOM into defense and electronic warfare applications, it exemplifies the kind of dual-use innovation that supports Europe’s strategic autonomy while remaining interoperable with allied systems. The following analysis delves into QuadSAT’s corporate structure, technological portfolio, and its alignment with European strategic objectives, painting a comprehensive picture of a company at the crossroads of space technology and defense innovation.
