QuadSAT Secures €5 Million Funding to Progress Radio Frequency Geolocation Technology
QuadSAT: Revolutionizing RF Testing for Defense and Space Operations
QuadSAT, a Denmark-based aerospace and defense startup, is making waves in the industry with its innovative drone-based radio frequency (RF) testing and geolocation technologies. The company's primary mission is to ensure spectrum assurance for military, space, and satellite operators, addressing the growing need for situational awareness against RF threats.
Recently, QuadSAT extended its Series A funding round with an additional €5 million, bringing the total to €5 million. This funding will be used to accelerate the development of QuadSAT's drone-based RF testing and geolocation technologies, with a focus on military applications.
QuadSAT's standout offering is its RF geolocation toolset, which is increasingly used to identify, locate, and analyze signals in contested environments. The company's systems offer dynamic, cost-effective, and accurate RF testing capabilities, making them essential tools for military, intelligence, and commercial customers.
One of the key advantages of QuadSAT's technology is its portability and compliance with various testing standards. This addresses a gap in conventional testing methods, allowing for more efficient and modernized testing of electronic warfare and satellite systems.
The funding round was led by Join Capital and North Ventures, with participation from Seraphim Space Capital and Denmark's Export and Investment Fund (EIFO). This investment strengthens QuadSAT's financial and R&D capabilities, enabling the company to expand its military and potentially commercial footprint.
QuadSAT's strategic partnership with UAV manufacturer Skyeton is another testament to its position as a key player in the drone technology sector. The collaboration involves integrating advanced RF spectrum monitoring into fixed-wing UAVs such as the Raybird UAS, providing scalable, mission-ready solutions for defense and public safety.
In summary, QuadSAT is revolutionizing the way electronic warfare and satellite systems are tested with its portable, repeatable, and compliant solutions. The company's recent funding and partnerships indicate strong momentum and a specialized niche within the defense drone and RF testing market. As multi-domain operations require RF situational awareness and counter-drone capabilities, QuadSAT's technology is becoming increasingly relevant and essential for military, intelligence, and commercial customers.
