GTD

What GTD does

GTD (legal name GTD System & Software Engineering) is a Barcelona-headquartered, privately held engineering company founded in 1987 that designs, develops, integrates, and operates mission-critical software and systems for European space, defense, scientific research, and energy customers. The company employs more than 500 engineers across six offices, serves clients in 26 countries, and has completed over 1,500 high-tech projects since inception. Its franchise rests on high-integrity software platforms qualified to aerospace and defense standards (AQAP 2110/2210, EN 9100, ISO 9001/27001/14001, CMMI Level 3), enabling it to bid on safety-critical programs where failure is not an option.

The core product portfolio spans flight and ground systems for European space programs (Launch Termination Computer System used at Andøya Space; Class A software for the Lunar Gateway i-HAB; MTG Lightning Imager algorithms; i-CDO launch operations IT for Kourou; SIBILA onboard AI prototype), defense and security systems (tactical communications, surveillance, C4I), and scientific infrastructure controls (GENROBOT SIL-2 platform for ITER fusion reactor robotics with F4E; LIPAc Machine Protection System with CERN; Haliade-X control system with Siemens Energy and GE; GAIA forest-fire management). GTD has also built a small ecosystem of operating subsidiaries — Portel (maritime-port SaaS), OpenChip (high-performance accelerators for European digital sovereignty), and LuxQuanta (quantum cryptography) — extending the corporate platform beyond the aerospace and defense core.

The business model is professional services plus mission-critical systems integration sold through direct enterprise and government engagement, with custom project-based pricing under long-cycle institutional contracts. Primary clients include ESA, CNES, F4E, CERN, SSC, Airbus, Leonardo, Thales Alenia Space, Siemens Energy, Navantia, Arianespace, and Air France. Disclosed annual revenue is approximately €90 million, with no external funding rounds reported; growth is being funded organically and complemented by strategic minority investments such as GTD's October 2025 participation in LuxQuanta's €8M Series A. The company is positioning around European strategic-autonomy themes (RISC-V processors via the CDTI- and EU-funded AR2SEC project, quantum-safe communications via LuxQuanta, European semiconductor accelerators via OpenChip).

Core offering

GTD designs, develops, integrates, and operates complex, mission-critical software and systems for space transportation, Earth observation, defense, scientific research, and industrial infrastructure. Its portfolio includes launch safety systems, satellite application software, defense C4I solutions, robotic control platforms for the ITER fusion reactor, particle accelerator control systems, offshore wind turbine controllers, and emergency-management platforms, sold primarily to space agencies, defense prime contractors, and large scientific institutions.

Product overview

GTD is a high-tech company specializing in the design, integration, and operation of complex, mission-critical applications and systems. The company operates a multi-product portfolio across five main sectors: Space & Security, Defense, Science/Infrastructure/Robotics, Microelectronics, and Logistics. The product portfolio includes: GENROBOT (high-integrity robotic control platform for ITER fusion reactor), AR2SEC (RISC-V based systems for critical sectors), Lunar Gateway i-HAB Application Software (for Moon-orbiting station), LIPAc Machine Protection System, Haliade-X Control System, SIBILA (onboard AI for satellite edge computing), i-CDO (launch operations IT systems), MTG Lightning Imager algorithms, and GAIA (forest-fire management system). GTD also maintains three subsidiary/sub-brand products: OpenChip (high-performance accelerators for digital sovereignty), LuxQuanta (quantum cryptography for secure communications), and Portel (SaaS platforms for maritime-port logistics).

Direct peers

• Beyond Gravity (formerly RUAG Space): European supplier of space products (structures, mechanisms, electronics) with comparable institutional client base and mission-critical space systems focus; overlaps with GTD's launch and spacecraft avionics/electronics capabilities.
• GMV: Spanish-headquartered aerospace, defense, and ICT engineering firm with comparable size, customer overlap (ESA, CNES, European primes), and mission-critical software/systems integration focus. The closest direct comparable to GTD by geography, scale, and capability mix.
• Kratos Defense & Security Solutions: US-listed provider of unmanned systems, missile defense, and space/launch range solutions including flight termination and range safety; the most direct Western commercial analog to GTD's launch termination computer business.
• SENER Aeroespacial: Spanish aerospace engineering group working on space mechanisms, GNC, and aerospace systems for ESA and European primes; competes with GTD for similar institutional engineering work-packets in Spain and across Europe.
• Elecnor Deimos: Spain-based space systems provider (part of Elecnor Group) delivering satellite systems, ground segment software, and space mission engineering — closely overlapping GTD's space transportation, Earth observation, and ground segment offerings.

Broad incumbents

• Hensoldt: German defense electronics and sensor house with a dedicated space domain (Hensoldt Space) covering mission-critical systems and avionics — broader portfolio but directly comparable on safety-critical defense and space electronics.
• Telespazio: Joint venture between Leonardo and Thales providing space services including ground segment operations, mission control, and satellite applications. Overlaps with GTD's i-CDO and ground systems work but at significantly larger scale and broader portfolio.
• Curtiss-Wright Defense Solutions: US-listed supplier of mission-critical defense electronics and rugged computing for aerospace and defense platforms; overlaps with GTD's high-integrity control systems and aerospace electronics portfolio, though at much larger scale.
• Indra: Spanish defense and IT systems prime with significant European institutional client overlap and a portfolio spanning defense electronics, C4I, and air traffic management — a much larger incumbent operating across several of GTD's verticals.

Regional players

• Kongsberg Defence & Aerospace: Norwegian defense and aerospace prime working on space, missile, and defense systems; comparable in domain (mission-critical systems, Andøya-area space activity) but headquartered in a different geography with broader portfolio.
