Modelling that depends on a cloud endpoint is modelling that stops at the air gap, at the edge, and in exactly the conditions the model exists to plan for.
and cloud-restricted networks are the normal operating environment, not the exception. A tool that needs an API key is unusable there. Deployment constraint · our position
propagation from a TLE is a published, checkable algorithm - the reference implementation is the standard, not a vendor. Orbital propagator · our position
specifies the rain-attenuation model a link budget must apply; the margin depends entirely on which model was used. RF link budget · our position
turbulence profile governs beam propagation. Stating the profile is what makes a laser propagation result comparable to anyone else. HEL beam propagation · our position
Every one of these is a published model with a stated boundary. That is the point: results that name their model and their assumptions can be checked by the other party, which is what makes them usable in an environment where you cannot simply be trusted.
Six that close the biggest gaps. 4 in the full aerospace and defense library.
The gap it closes. Standard propagation from a TLE with conjunction assessment, running locally, so the analysis is available where the network is not.
See it run in your browser →The gap it closes. Names the rain model and the BER relation it applied, so a stated margin can be reproduced rather than accepted.
See it run in your browser →The gap it closes. Turbulence profile and propagation range stated explicitly, because a spot size without them is not a comparable number.
See it run in your browser →The gap it closes. 3DOF with a configurable timeline and its model boundary stated plainly - what is modelled and what is not, rather than an unqualified answer.
See it run in your browser →These are deterministic models of published algorithms, with their limits stated in each result. They are not operational planning tools, not targeting systems, and not a substitute for authoritative mission software or the analysis of a qualified engineer. Every result carries a wall-time benchmark and a trust verdict on its arithmetic, which bounds the computation and says nothing about whether the model suits your problem.
Every tool above runs entirely in this browser tab. Nothing is uploaded, nothing is sent to a model, and each result cites the rule it applied.
