Spacebel

Spacebel, headquartered in Liège, Belgium and founded in 1988, is a Belgian space systems software and engineering company with 100+ employees — specializing in on-board flight software, ground control systems, mission planning applications, and automation solutions for European and international space programs, having contributed software and systems to over 50 space missions over three decades.

Spacebel's core competency is the development of safety-critical software for space applications: real-time mission data processing systems, satellite onboard software executing on space-qualified processors (LEON-based SPARC processors, RAD750, and RISC-V space processors), ground control system front-ends, and satellite simulation testbeds used by satellite operators for training and system validation. The company is an ESA-certified supplier and regularly participates in ESA mission development as a software subcontractor to prime satellite integrators including Airbus Defence & Space, Thales Alenia Space, and OHB.

Spacebel's mission portfolio spans Earth observation (Copernicus Sentinel ground processing software), navigation and science (GNSS receiver software), telecommunications (satellite network management), and planetary exploration (onboard data handling for ESA science missions). The company developed ground segment software for ESA's PROBA series of small experimental satellites, including PROBA-V vegetation monitoring — gaining end-to-end mission experience that positions it for primary system roles on future small satellite programs.

Spacebel's European office network — Liège (headquarters), Brussels, Toulouse (France, co-located with CNES and Airbus), and Warsaw (Poland) — reflects the company's strategy of embedding teams near Europe's major space centers. The Toulouse presence is particularly strategic for engaging with CNES programs and the large Airbus Defence & Space satellite production facility. The Warsaw office serves Poland's growing ESA member participation programs and Central European space market.

Spacebel competes with GMV (Spain), Rhea Group (Belgium), and Telespazio (Italy) for ESA and European national space agency software development contracts.
