Home Focusear Passive RF tracking system to support Flight Dynamics and Space Surveillance activities Print What is Focusear? Passive RF tracking system Focusear is the GMV system to track satellites based on Passive RF technology.Currently tracking all GEO satellites emitting in Ku band over Europe and providing data to the EU SST since Summer 2024.Being extended to also support other GEO regions as well as satellites in MEO and LEO orbital regimes.Based on Time Difference of Arrival (TDoA) and Frequency Difference of Arrival (FDoA) data generated by a dedicated network of stations. +60 GEO telecom satellites in 50E-50W longitudes emitting in Ku band over Europe systematically tracked 24x7 Providing continuous and frequent tracking and orbital data with very low latency (few minutes) and top-class accuracy (10ns, equivalent to 3m) News Space GMV makes headway in groundbreaking passive satellite tracking techniques Space SafetyTechnology Demos Go, Hera go!
