About Vegvisir
Mixed Reality Situational Awareness Systems

Our story
Defensphere OÜ was founded in January 2021 by eight founders from Estonia and Croatia who were all experienced professionals and experts in the military, defence industry, government, FPV drone business, military camera business, engineering, and international business development in the startup world.
The original idea of the Vegvisir system was developed by our founders with military backgrounds who had been stuck themselves in armoured vehicles in the middle of the battles in Afghanistan and other military deployments. Back then they heavily missed technical tools that would help them out in their problem.
Eight founders then decided to develop the Vegvisir system by combining the military requirements with the technical expertise from the ultra low latency based FPV drone business.
Vegvisir Mixed Reality System
What We Do
Our system creates a 360° visual dome around the vehicle and enables multi-user, simultaneous, live Augmented Reality or Mixed Reality feed with very low latency. The system provides personnel of an armoured vehicle a visual understanding of the immediate surroundings and areas of interest up to 10 kilometers away.
Vegvisir is a next-generation Mixed Reality Situational Awareness System (XRSAS) that delivers unmatched real-time visibility and decision support for armored vehicle crews, remote operators, and commanders. By fusing live sensor feeds with intuitive mixed-reality interfaces, Vegvisir turns complexity into clarity — empowering faster, smarter decisions on the battlefield.
Designed for manned and unmanned platforms alike — including MBTs, IFVs, APCs, and more — Vegvisir transforms any vehicle into a connected digital hub. It integrates visual and thermal cameras, long-range sensors, and a high-performance mission computer with ruggedized head-mounted displays (HMDs). The result: seamless 360° situational awareness, ultra-low latency, and multi-user collaboration.
Whether operating from the front lines or a hidden command post, Vegvisir provides crews and commanders with the tools to observe, orient, decide, and act — faster and more effectively than ever before.
