OrbitGuardians

OrbitGuardians is a Harwell, UK-based space situational awareness (SSA) and space traffic management (STM) company founded in 2020, developing debris tracking, collision avoidance analytics, and orbital safety services for satellite operators navigating increasingly crowded orbital regimes. The company is based at the Harwell Space Cluster — adjacent to the UK Space Agency and RAL Space — giving it access to the UK SSA and space surveillance community including the UK Space Operations Centre (UKSpOC) at RAF High Wycombe, which provides the UK's national SSA picture. OrbitGuardians' products include conjunction analysis services that process orbital catalog data (from U.S. Space Force's Space-Track, ESA DISCOS, and commercial tracking providers) to identify close approach events and compute probability of collision (Pc) for active satellites, providing actionable alerts with recommended maneuver burn solutions. As mega-constellations from SpaceX (Starlink), OneWeb (Eutelsat), and Amazon Kuiper add thousands of active spacecraft, conjunction frequency has increased dramatically — making professional SSA services increasingly critical for operators who previously relied entirely on free U.S. 18 SDS data. OrbitGuardians targets mid-tier operators (individual to small fleet satellite operators) who need higher-quality conjunction data and maneuver support than free sources provide but cannot afford dedicated internal SSA teams. The company competes with LeoLabs (ground radar network, USA), ExoAnalytic Solutions, Slingshot Aerospace, and Seradata (part of Northrop Grumman) in the commercial SSA services market, as well as ESA's voluntary Space Debris Mitigation services and the UK CAA's emerging STM framework.
