In orbit, you don't get
a second pass.
A spacecraft is unreachable the moment it leaves the pad — every analysis that put it there has to be right, reproducible, and defensible years later when the anomaly review opens. We serve space + satellite programs with software, not cranes : deterministic orbital, mission, and payload verification compute on Heisen, post-quantum crypto for space-ground links, and Murlink clean-handling rigging for payload + ground ops. Same number every run, audit-trailed, sovereign. The program flies the mission ; we make the compute behind it reproducible.

Six exposures across the mission compute.
Space risk is compute risk before it's hardware risk : an analysis that can't be reproduced, a crypto link that won't survive a quantum adversary, a verification chain that doesn't hold at the anomaly review. The exposures below are what deterministic, audit-grade software exists to control — the software half of a space program done to the standard.
Non-reproducible analysis
If an orbital or mission analysis gives a different number on re-run, the anomaly review can't trust any of it. Heisen is deterministic by construction — same input, same result, with the inputs + version pinned for replay years later.
Harvest-now-decrypt-later
Space-ground telemetry + command links intercepted today can be decrypted once a quantum computer exists. Post-quantum crypto (NIST FIPS 203/204/205) on the link closes the harvest-now-decrypt-later window before it opens.
Verification chain gap
A verification step that isn't recorded, attributable, and reproducible is a gap the review will find. The compute is audit-trailed end to end — every analysis traceable to its inputs, code version, and operator.
Clean-handling contamination
Steel rigging sheds particulates that contaminate a payload in a clean room. Murlink synthetic rigging is non-marking + clean-room-compatible — the handling that doesn't compromise the payload.
Foreign software dependency
Mission-critical compute on a foreign-controlled platform is a sovereignty + ITAR exposure. Heisen is Canada-built + sovereign — the program owns the software, deployable in its own environment.
Numerical drift across toolchains
Floating-point results that drift between machines or library versions silently corrupt a long analysis. Deterministic compute pins the numerics — the result is the result, regardless of where it runs.
Software-first. The compute behind the mission.
Space + satellites is a software engagement for us — deterministic compute, post-quantum crypto, verification record, plus clean-handling rigging. Six concrete fits.
Orbital + mission verification compute
Deterministic orbital-mechanics, mission-timeline, and constellation-geometry compute — reproducible to the bit, version-pinned, replayable at the anomaly review.
Payload + sensor data verification
Deterministic payload + sensor data-reduction pipelines — every transform recorded + reproducible, so the science (or the intel) holds up to scrutiny.
Post-quantum space-ground links
NIST PQC (FIPS 203/204/205) integration for telemetry + command links — closing the harvest-now-decrypt-later window on long-lived assets.
Verification + anomaly-review record
An audit-trailed verification chain — every analysis attributable, contemporaneous, reproducible. The record the anomaly board expects, built as the work happens.
Clean-room payload + ground rigging
Dyneema® synthetic rigging for payload + ground handling — non-marking, clean-room-compatible, non-conductive. The handling that doesn't contaminate the payload. Authorized Quebec distribution.
Embeds into your mission stack
Heisen embeds by API into your existing mission-analysis / GMAT / STK-adjacent stack — the deterministic layer alongside your tools, not a replacement.
Space & Satellites in the field
From sector context to the lifts we engineer — a look at where this work happens.
The standards we work to.
We build the software to the aerospace + space-systems standards your program is reviewed against, and supply rigging to the crane-rigging standard. The spacecraft + mission engineering is the program's — we build the deterministic compute + verification around it.
European Cooperation for Space Standardization
The ECSS engineering + software standards govern space-system development. Our verification software is built to align to the ECSS software-product-assurance posture your program follows.
Models + simulations standard
NASA's standard for the credibility of models + simulations — verification, validation, reproducibility. The discipline our deterministic compute is built to satisfy.
Aerospace quality management
The aerospace QMS standard. Our software-development posture is built to slot into an AS9100D-audited supply chain.
Post-quantum cryptography
ML-KEM, ML-DSA, SLH-DSA — the NIST PQC standards. Integrated on space-ground links to protect long-lived assets against future quantum decryption.
Space data systems standards
The CCSDS standards for space telemetry + command. Our link + data software aligns to the CCSDS framework your ground segment uses.
Slings + rigging
Governs slings + rigging. Cited on the Murlink rigging spec for clean-room payload + ground handling — each component rated + contamination-selected.
Software-led. Murlink for handling. No cranes here.
Space is one of the two sectors where our crane-lift pillars step back. The engagement is software-first, with Murlink for clean handling. Here's how each pillar applies — honestly, including where it doesn't.
Sealed plans + emergency response
Not applicableHeavy crane lifts don't apply to a space + satellite program — there's no crane pick in our scope here. The engagement is the deterministic software and the clean-handling rigging.
Distribution + training + implementation
Not applicableWith no crane lift in scope, CRANEbee lift simulation doesn't apply to this sector. Our modeling value here is in the deterministic mission + payload compute, not a crane study.
Distribution + advisory + training
Dyneema® synthetic rigging for clean-room payload + ground handling — non-marking, clean-room-compatible, non-conductive, no particulate shed near the payload. Authorized Quebec distribution, with advisory on the spec.
Deterministic engineering platform
The whole engagement. Deterministic orbital / mission / payload verification compute + post-quantum space-ground crypto on Heisen — reproducible to the bit, audit-trailed, plus Maxor Audit + Maxor Ground. Sovereign, Canada-built. Heisen embeds into your mission stack by API.
Compute that gives the same answer at the anomaly review.
For space, the engagement is the software — anchored on Heisen. We build deterministic, audit-grade compute : same engineering posture, same team kickoff to go-live, sovereign by default. An analysis that returns the same number on re-run years later, when the review board wants to retrace exactly how the mission was verified. Engineered in Canada, owned by you.
Heisen — our deterministic intelligence layer — is optional on any build: embed it or not, your call. Either way it plugs into a fresh custom app or your existing third-party software via API.
Deterministic mission-verification compute
Orbital, mission-timeline, and constellation-geometry analysis that's reproducible to the bit, version-pinned, and replayable at the anomaly review — not a black box that drifts between runs.
Post-quantum space-ground crypto
NIST PQC (FIPS 203/204/205) on telemetry + command links — closing the harvest-now-decrypt-later window on assets that will fly for a decade or more.
Payload data-reduction + verification record
Deterministic payload + sensor pipelines with an audit-trailed verification chain — every transform reproducible, so the science or the intelligence survives scrutiny.
