Pioneering knowledge in satellite-based QKD system design, quantum-safe encryption architectures, and sovereign communication networks. Our expertise bridges the gap between quantum physics research and operational space deployment — from photon source engineering to ground terminal integration.
Comprehensive knowledge in building and operating universal spectrum analysis tools — quantitative time-domain interference assessment, CDF/PDF statistical engines, and regulatory filing support. We understand how to make NGSO constellations, GEO networks, and ground systems share spectrum harmoniously.
Comprehensive knowledge spanning the full lunar mission lifecycle — descent trajectory design, landing site selection and hazard avoidance, touchdown dynamics and shock attenuation, thermal survival through the 14-day lunar night, power management during eclipse periods, surface mobility and rover operations, regolith interaction, in-situ resource utilisation concepts, and Earth-return communication link engineering. Our expertise extends to proposal engineering and technical bid preparation compliant with NASA and ESA development standards.
End-to-end mastery of Launch and Early Orbit Phase — from pre-launch rehearsals and contingency planning through orbit acquisition and commissioning. Our knowledge covers spacecraft ranging from nanosatellites to multi-tonne platforms, encompassing attitude acquisition, solar array deployment sequencing, and propulsion manoeuvre planning across all orbit regimes.

Based in Luxembourg at the heart of Europe's space ecosystem, Equinox Consulting was founded by space industry veterans who believe great missions deserve dedicated, independent engineering support.
We are not a staffing agency. We are engineers and project managers who have designed satellites, managed multi-million euro ESA programmes, coordinated spectrum for global constellations, and operated spacecraft from launch through end-of-life. We bring that hands-on experience directly to your mission.
Our team has worked across the full spectrum of space missions — from 3U CubeSats to 3+ tonne GEO telecommunications platforms, from lunar landers to direct-to-device constellations. We've sat in mission control during LEOP campaigns, built spectrum analysis tools from scratch, led thermal design for lunar surface survival, and navigated the regulatory frameworks of ESA, NASA, and the European Commission.
As an independent consultancy, we have no hardware to sell and no platform to push. Our only product is expertise, applied with rigour and delivered on time. We work as an extension of your team — embedded, accountable, and aligned with your mission's success.
Equinox Consulting S.à r.l. is incorporated in Luxembourg, strategically positioned near ESA's European Space Security and Education Centre (ESEC) in Redu, SES headquarters in Betzdorf, and the University of Luxembourg's SnT research centre.
No vendor lock-in, no product bias. We recommend what's right for your mission, not what's right for our balance sheet.
From feasibility study to on-orbit commissioning. We don't hand off — we stay with your mission through every phase.
ECSS, CCSDS, PUS, NASA NPR, ITU-R, 3GPP — we don't just know the standards, we've applied them operationally on real missions.
Quantum communications, AI in space, 5G-NTN, D2D — we bridge research and commercial deployment for next-generation systems.
