The solver that doesn’t crash when sensor data turns adversarial. Digital twins that actually match the platform. Embedded math that runs the same on the workstation, the HIL rig, and the airframe — and an evidence base built to survive a program-office audit.
Proofs of concept
Each POC opens with a scenario, walks through what SolvNum changes, and ends with a demo number plus a SHA-256 you can re-derive on your own hardware.
25-platform swarm, 30 randomized runs. Float64 stack: 1,765 collisions, 98.3% threat-tier unanimity. SolvNum stack: 0 collisions, 100% unanimity, hardware-stable hash.
5-node, 4-hardware-class JADC2 vignette. All four capabilities active simultaneously, end-to-end. One SHA-256 every node produces independently. One attestation page replaces dozens of per-system certifications.
Sim, trainer, and deployed system run on three different hardware generations and produce the same SHA-256. The 'rehearsal-to-deployed drift binder' goes away.
Defense capabilities
The same noise-immune solver, embedded-first design, and audit-grade evidence base show up across air, sea, space, sensors, sustainment, and program acceptance.
Air & Autonomy
Flight controllers, autopilots, and autonomy stacks are only as good as the math inside them. Our solver runs the same compiled binary in MATLAB, on a HIL rig, and on the airframe — and survives the kind of noisy, impulsive, non-stationary sensor data that breaks every other integrator at exactly the moment it matters.
Sustainment & Readiness
Predictive maintenance and fleet-readiness twins fail because the on-board model and the cloud model are different software. We collapse them into a single binary, so a divergence between the platform and its twin means a real fault, not a software artifact. Less alert fatigue. Fewer false-positive inspections. Higher mission-capable rate.
Sensors & Fusion
Tactical data links and sensor-fusion buses compress a rich upstream picture into a small standardized message. Bounded Network Enrichment recovers the bounded intelligence dimensions inside the existing message envelope — validated on a 590,540-event benchmark, ready to adapt to a representative data-link environment under appropriate agreement.
Targeting & Decision Support
Targeting, mission planning, and clearance decisions all need to know how confident the math actually is. Our Real-Time UQ configuration delivers calibrated uncertainty envelopes from a single solve — fast enough to sit inside an autopilot, an operator console, or an airworthiness certification harness instead of a Monte Carlo data-center campaign.
Space & Long-Duration
Orbit propagation, attitude control, and long-duration thermal models accumulate drift in standard solvers. SolvSRK is validated for 100,000 integration steps with no drift — across stiffness regimes from gentle dynamics to eigenvalue ratios of 10⁶ — without per-system tuning.
Naval & Subsurface
Subsurface navigation, current compensation, and drift correction live or die on solver behavior under sensor noise. Our solver was discovered through validation against exactly that regime — built embedded-first, in C, with airgapped license enforcement suitable for classified firmware.
Determinism & Replay
Mission orders are approved on one machine, executed on another, and replayed on a third — and the numbers have to be the same. SolvNum is a deterministic real-number primitive that produces bit-identical arithmetic across x86, ARM, NVIDIA GPU, and WebAssembly. One SHA-256 receipt proves plan = flight = replay. A cross-target equivalence argument that fits on one line of a DO-178C / ISO 26262 certification package.
Program Audit & Acceptance
Every numerical claim on this site traces back to a test, a seed, and a verdict in our internal evidence register. The same standard travels with the products you buy: SolvScout fingerprints your system, SolvTune ranks every candidate solver with dead zones called out, and SolvBench archives the decision in an encrypted, replayable profile — so “why this solver?” has a defensible answer at TRR, milestone audit, and Section 818 review.

The product line
Each product brief below opens with a scenario, then walks through what it is, who uses it, why it’s defensible, and how the underlying claims survive an audit.
Same binary. Workstation, HIL rig, airframe.
GN&C engineers spend years closing the gap between the solver that worked in simulation and the solver that ships on the flight computer. SolvSRK is one C-native solver that runs in both places with identical behavior — survives contested sensor data, fits inside ITAR-compliant airgapped pipelines, and ships under a compile-time license with no phone-home.
Real parity between the platform and its twin.
Predictive maintenance, fleet readiness, and after-action analysis all depend on the on-board model and the cloud twin agreeing. Today they don't — different solvers, different physics, manual reconciliation. SolvSRK runs the same compiled binary on the edge and in the cloud, so divergence means a real fault on a real platform, not a software artifact.
Controllers that know how confident they are.
Autonomous platforms today carry one fixed safety margin — the worst case under the noisiest sensor data, the densest jamming, the most degraded comms. That margin is always on. SolvSRK tracks state-space uncertainty inside the solve and exposes it as a control signal, so the autopilot tightens when the picture is clean and backs off when it isn't, automatically.
Calibrated confidence on the operator's display.
Mission planning, targeting decisions, and certification of safety-critical software all depend on knowing how confident the math actually is. The classical answer — Monte Carlo — is a data-center weekend, not a real-time loop. SolvSRK delivers calibrated uncertainty envelopes from a single solve, fast enough to sit inside the autopilot, the operator console, or the certification harness.
Plan, flight, and replay agree to the bit.
Today the mission you approved on the screen, the mission the platform actually flew, and the mission the incident-review team replays in the lab are three slightly different sets of numbers — because they ran on three different computers. SolvNum is a deterministic real-number primitive that produces bit-identical arithmetic across x86, ARM, NVIDIA GPU, and WebAssembly. One SHA-256 receipt proves plan = flight = replay.
Recover the intelligence the link compression throws away.
Tactical data links — Link-16, CDL, contested low-bandwidth comms — compress a rich sensor picture down to a tiny standardized message before it reaches the consumer. We sit on the network side, extract bounded intelligence signals from the full upstream picture, and deliver them inside the existing message envelope. Validated on a 590,540-event benchmark with 5-fold cross-validation.
Pick the right solver — with evidence the auditor accepts.
SolvScout fingerprints your ODE system. SolvTune benchmarks every candidate solver on it and produces a ranked, dead-zone-honest comparison report. Drop-in replacement for the “we picked it because the senior engineer used it in 2008” conversation that does not survive the next program review.
Mission control for the math inside your simulation.
The desktop application that turns solver selection from guesswork into evidence. SolvBench orchestrates Scout, Tune, and the SolvEngine runtime — characterize the system, benchmark the candidates, apply the winning configuration, watch the solver work in real time, and archive every decision in an encrypted profile database the auditor can replay.
How we earn the right to make every claim on this site.
Every benchmark, every dead zone, every survival number on this site came out of an AI-orchestrated research lab we built to validate our own solver. One engineer. Six weeks to stand up. Over 1 trillion scalar observations, 1 billion validated data points (the nearest credible competitor has 30,000), 821 billion function evaluations, and zero retracted findings.
