Share My Space

Share My Space (SMS) is a Paris-based French commercial space traffic management (STM) and space situational awareness (SSA) company founded in 2017 by Jean-Marc Nasr (former Airbus EVP Space) and Romain Lucken, providing satellite operators with AI-powered conjunction risk assessment, collision avoidance maneuver planning, and orbital traffic monitoring services — with a particular focus on delivering European sovereign SSA capability independent of U.S. government data sources.

The company's core product is SureSat: a satellite operator-facing web platform and API that delivers enriched conjunction data beyond the standard public Conjunction Data Messages (CDMs) issued by USSPACECOM's 18th Space Defense Squadron via Space-Track.org. Share My Space improves upon public CDM data by ingesting multiple data sources — proprietary optical tracking network data, commercial radar feeds, and historical orbit determination records — and running AI-enhanced orbit determination algorithms that reduce uncertainty in predicted satellite positions, improving the accuracy of probability-of-collision (Pc) estimates critical for maneuver decision-making. False alarms (Pc warnings that turn out unnecessary) cost operators fuel and operational time; missed threats are catastrophic.

Share My Space operates a proprietary network of optical telescope sensors for independent RSO (resident space object) tracking, contributing to the EU SST (Space Surveillance and Tracking) consortium — the European framework pooling national SSA capabilities from France (CNES/ONERA), Germany (DLR), Spain (GMV), Italy (ASI), and others. European strategic autonomy in space surveillance — avoiding dependence on the U.S. Space Force catalog as the sole authoritative data source — is a key policy driver, with CNES, ESA's Space Safety Programme, and the EU Directorate for Defense Industry all actively funding alternative SSA capabilities.

France's 2008 Space Operations Law (LOS), updated in 2017 and 2023 with mandatory conjunction assessment provisions, creates regulatory compliance demand that Share My Space directly addresses. Growing commercial satellite populations in LEO — Starlink, OneWeb, Kuiper — dramatically increase conjunction event rates, driving demand for higher-cadence, more precise screening services. Competitors include LeoLabs (radar SSA), Slingshot Aerospace (data analytics), Kayhan Space (autonomous maneuver planning), and COMSPOC (Ansys commercial SSA catalog).
