Space Systems Engineering,
Automated.

A physics-informed AI engine that accelerates your mission analyses from Phase 0 through B1, so your engineers focus on the mission, not spreadsheets.

Traceable. Auditable. Sovereign.

Under the hood

You describe your mission. AI orchestrates the engineering. Physics computes every number.

Plain language. Any starting point.

Selects and sequences the right analyses.

Layered fidelity per phase. Predefined workflows.

Budgets, 3D view, compliance. All traceable.

Sovereign EU — OVHcloud, France Every result traceable to its physics model Phase 0 → B1 with ECSS phase gates

See Vecteur in Action

From a mission statement to validated Phase A — orbit, budgets, link margins, compliance — in one session.

Your Phase A takes 3 weeks, 2 experts, and 4 tools. It should take one conversation.

TODAY
WITH VECTEUR
Fragmented tools. Orbit in STK, sizing in Excel, coverage in MATLAB — nothing talks to each other
One mission statement, all domains coupled in a single run
Siloed data. Each subsystem budgeted in isolation — no cross-check until integration
Power, thermal, mass, link converged together — coupled by design
Specialist bottleneck. Coverage analysis needs a specialist and days of setup
Coverage, contacts, ground stations computed in seconds
No traceability. Results live in PowerPoint — no reproducibility
Full audit trail — every number traceable to its physics model

What your team unlocks

Built for every engineer on your team — not just the one who knows the tools.

MISSION STATEMENT

"Design an EO constellation with 5m GSD, global daily revisit, 5-year lifetime"

1

System Architecture

Orbit design, Walker constellation sizing, ground network, launcher pre-selection

2

Spacecraft Sizing

Power, mass, thermal, link, delta-V budgets — iteratively converged

3

Hardware Selection

Real components from 937+ products catalog, BOM, resource validation

4

Verification & Compliance

Coupled E2E simulation, compliance matrix, margin analysis, risk register

OUTPUT

Converged PDR datapack — budgets, BOM, simulation data, compliance matrix, full traceability

Trusted Results, Proven Precision

12 months to orbit, millions on the line. You need speed — but you can't afford wrong numbers. Every result in Vecteur is cross-validated against industry reference tools.

Multi-Tool Cross-Validation

Every calculation is verified against NASA SPICE, ESA Orekit, NASA GMAT, and industry-standard toolkits. Same inputs, same outputs -- if the reference tools agree, so do we.

From Concept to Confidence in Hours

Traditional validation takes weeks. Vecteur's pre-validated engine lets you design, simulate, and verify in a single session -- with full audit trail.

Full Transparency

We document every limitation. No black boxes. You know exactly what you're getting -- and what requires external verification for flight-critical applications.

Real Mission Heritage

Benchmarked against Falcon 9, Starship, and operational constellations. Not theoretical -- validated against hardware that's actually flown.

Cross-validated against industry standards & research:

NASA SPICE
Orekit
AAS/AIAA
IAC
ITU-R
CCSDS
