Discover & Define

We assess your mission concept, business objectives, and technical requirements. Feasibility studies, trade-off analyses, and a clear project definition emerge.

02

Architect & Design

Systems engineering, thermal analysis, spectrum coordination, and ground segment architecture — all designed to ECSS and mission-specific standards.

03

Build & Validate

Development, integration, and rigorous testing. From PDR through CDR to qualification, every milestone is managed with PMP-grade discipline.

LEOP execution, commissioning, and transition to nominal operations. Ongoing OaaS support with structured SLAs to maximize your mission's lifetime value.

Who We Are

Independent engineers with a mission

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.

Independence

No vendor lock-in, no product bias. We recommend what's right for your mission, not what's right for our balance sheet.

End-to-End Delivery

From feasibility study to on-orbit commissioning. We don't hand off — we stay with your mission through every phase.

Standards-Driven

ECSS, CCSDS, PUS, NASA NPR, ITU-R, 3GPP — we don't just know the standards, we've applied them operationally on real missions.

Emerging Technology

Quantum communications, AI in space, 5G-NTN, D2D — we bridge research and commercial deployment for next-generation systems.
