Propagate orbits
Model gravity, manoeuvres and atmospheric effects across the Low Earth Orbit regime, on an engine written for that job.
Mission planning software for Low Earth Orbit.
KnownX MPT is an orbital simulation and mission planning tool. Its physics is checked against public tracking data for real satellites before a result is called accurate.
Built by KNOWN Corporation in Kigali, Rwanda.
One tool from first orbit sketch to the report.
Mission teams usually stitch this work together from separate programs. KnownX MPT keeps the scenario, the physics and the outputs in one place, so a number in a report can be traced back to the run that produced it.
Check them against real satellites
Run the same orbit as a documented satellite and measure how far the result drifts from public TLE records.
Plan and report
Build a mission scenario, change an assumption and see what moves, then export outputs that name the parameters behind them.
- ISS (Zarya)Low orbit
- Landsat 9Sun-synchronous
- GPS BIIR-5Medium orbit
Show the figures as a table
| Satellite | After 6 h | After 24 h | After 48 h | After 72 h |
|---|---|---|---|---|
| ISS (Zarya) | 0.5 km | 1.7 km | 2.6 km | 2.3 km |
| Landsat 9 | 0.0 km | 1.0 km | 4.3 km | 9.9 km |
| GPS BIIR-5 | 0.1 km | 0.8 km | 2.2 km | 4.3 km |
Accuracy is a test result, not an impression.
A trajectory can look right and still be wrong. KNOWN validates the engine against documented orbital records from Space-Track and CelesTrak. When a result diverges, the physics is corrected before the next milestone starts.
The chart shows the current result for three real satellites: how far KnownX MPT's propagation is from SGP4, the standard model for published orbital elements, after one, two and three days.
The KnownX Mission Companion works beside you.
KnownX MPT includes an AI assistant in a panel next to the simulation. It reads the mission you have open (spacecraft, propellant, sequence, trajectory and validation status), answers questions about it, and prepares manoeuvres and settings changes for you to review.
Ask
Questions about the mission in front of you, or about orbital mechanics in general.
Review
Changes it prepares appear as cards. Nothing is applied until you accept it.
Apply
Accepted changes run on the same engine as anything you set by hand.
From mission context to technical output.
The same four steps every time. Each one produces what the next one needs.
1
Describe the mission
Orbit, spacecraft and constraints for the scenario you are evaluating.
2
Set the assumptions
Propagation settings, perturbation models and mission variables.
3
Run and compare
Propagate, then compare against public TLE data for the same object.
4
Export
Trajectories, timelines and comparison data, ready to review or cite.
Open to institutions first.
Research institutions, aerospace programmes and technical organisations can evaluate KnownX MPT with a free trial, then license it per seat. Pricing is published, quotes are sent as a link you accept online, and you manage your licences and invoices from your own account.
