Low Earth Orbit analysis
Propagate and analyse orbital behaviour across the LEO regime. Model multi-body gravitational effects, atmospheric influences, and propulsive maneuvers with physics that is verified against independent reference data.
Digital mission engineering for Low Earth Orbit.
KnownX MPT is an orbital simulation and mission planning tool built on a TLE-validated physics engine. Work from mission context, adjust what matters, and export technical outputs you can cite, with the KnownX Mission Companion alongside to answer questions and prepare changes for your review.
One platform for LEO mission analysis.
KnownX MPT is designed for the engineering work that defines a Low Earth Orbit mission: analysis, planning, validation and reporting, all on a physics foundation that is verified, not assumed.
Mission planning
Design mission scenarios around your operational context. Define spacecraft characteristics, orbital parameters, and constraints. Adjust assumptions and see the impact of each change in real time.
Trajectory validation
Compare propagation results against documented orbital records using public TLE data from Space-Track and CelesTrak. Measure position divergence and correct models before advancing milestones.
Coverage and access
Determine satellite visibility windows, ground contact periods, and coverage zones for your specific constellation or single-satellite mission parameters.
Technical reporting
Generate professional technical outputs including trajectories, timelines, and comparison data. All exports are traceable to the propagation parameters that produced them.
3D mission playback
Visualise complete missions in a time-dynamic 3D environment. Orbital paths, ground tracks, and geometric relationships are rendered from the same physics engine driving the analysis.
From mission context to technical output.
KnownX MPT follows the sequence mission teams already work in. Each step produces the inputs the next one needs, with validation along the way.
1
Define your mission
Set up your mission context: orbit parameters, spacecraft characteristics, operational constraints. The scenario becomes the working environment for all subsequent analysis.
2
Configure the models
Select propagation settings and model parameters that match your analysis requirements. Choose from available physics models and configure them to your scenario.
3
Run and validate
Execute propagation through the KNOWN physics engine. Results are computed against validated models and can be compared against public TLE reference data for accuracy verification.
4
Export and decide
Export clean technical outputs (trajectories, timelines, comparison reports) ready for review, reporting, or integration into your broader analysis workflow.
What KnownX MPT lets you do.
Each capability is described by what you can accomplish with it. The engine, architecture and validation method are covered in the help.
Orbit propagation and analysis
Propagate orbits with validated physics for any LEO scenario. The engine handles multi-body gravitational effects, propulsive maneuvers, and atmospheric influences — all verified against independent reference data.
Accuracy validation against TLE data
Validate propagation against public TLE data from Space-Track and CelesTrak. Import a documented satellite, run the same propagation in the KNOWN engine, and measure position divergence as a quantitative result.
Mission scenario design
Define spacecraft characteristics, orbital parameters, time windows, and constraints. Adjust assumptions freely — the engine recalculates and surfaces the impact of each change. Scenarios are preserved across sessions.
Reporting and data export
Export trajectories, timelines, comparison data, and analysis results in standard formats. Customize reports to highlight the metrics that matter. All exports are traceable to propagation parameters and validation sources.
3D visualisation and playback
Watch missions unfold in a time-dynamic 3D environment. Orbital paths, ground tracks, and geometric relationships are rendered from the same physics driving the analysis — what you see is what the model calculates.
API and systems integration
Automate workflows and integrate with existing engineering tools via the API. Programmatic access to scenario creation, propagation control, and data retrieval enables KnownX MPT to function within your systems architecture. Available with Enterprise tier.
KnownX Mission Companion.
An AI assistant built into the workspace, in a panel beside the simulation. It works from the mission you have open, answers in plain language, and prepares changes that you apply or dismiss.
It reads the mission you have open
The spacecraft and bodies in the scenario, propellant, mass and engine figures, the force models switched on, the mission sequence, the predicted trajectory, any closest approach, and how far the run has been validated.
It answers questions
About this mission, about why the simulation is behaving as it is, or about orbital mechanics in general. It quotes figures from the mission with their units.
It proposes changes for you to review
Ask for a burn, a launch sequence or a change of settings and it prepares the steps. Each proposal appears as a card you accept or reject. A plan of several steps is accepted once, as a whole.
It checks the request against the spacecraft
Before proposing a manoeuvre it works from the propellant, mass, specific impulse and thrust available. If what you asked for cannot be done with what the craft has, it says so and says what would be needed.
Nothing is applied without you
A proposal stays a proposal until you accept it, and you can dismiss it instead. The run, the sequence and your recorded data change only when you say so.
The Companion needs an internet connection. It reports validation status as the workspace shows it. More in the questions and answers.
