PLANETARY DEFENCES / PD
Five space-risk domains. One connected intelligence layer.
PD connects space conditions, mission data and sensor evidence to show what is changing, where it matters and whether the available information can be trusted.
Research-backed. Built for human decisions.

01 WHY CONTEXT MATTERS
The same warning can mean different things to different systems. What matters depends on the asset, the place and the available evidence.
THE ENVIRONMENT
The environment is shared. The useful question depends on the system you are looking after.
Space conditions.
Your asset and location.
A warning tells you something changed.
The next question is what matters here.
02 / THE PD PLATFORM
Explore orbit forecasts, spacecraft readings and changing space conditions—alongside the evidence behind each result.
Research-tested capabilities and engineering demonstrations. Live mission use requires a separate customer evaluation.
For everyday operations and changing space conditions alike.
03 / MEASURED RESULTS
Separate historical studies. Specific comparisons. Explore what each result measures and how it was tested.
64.47% lower average 3D error · 48 h
Rounded metres. Historical 48-hour refinement across 145 forecasts using the same public rapid-orbit inputs. Not a competitor comparison.
58.62% fewer classification errors
Selected OPS-SAT completed segments, randomly split, against the version-matched author example. Not advance failure prediction.
lower overall Hp60 forecast RMSE · 3 h
3-hour Hp60 forecasts · RMSE across 52,123 historical samples. Measures index values, not storm-warning accuracy.
These studies are separate from the illustrative storm story. The percentages measure different kinds of error—not one overall accuracy.

Take orbit forecasting as one example. Compare the recorded results at 12, 24 and 48 hours, using the same starting data.
lower average position error
145 forecasts · Compared using the same historical inputs
Sentinel-3A / 3B / 6A public rapid-orbit products. Historical forecast correction, not independent orbit determination or a competitor comparison.
Follow the study, not just the percentage.
The question, the comparison and what the result supports.
05 / CAN THE READINGS BE USED?
Understanding the environment is one question. Knowing whether the readings can be used is another. PD’s sensor-assurance demonstrator makes incomplete or conflicting information visible.
Illustrative mission-assurance example. Not operational detection accuracy.
ILLUSTRATIVE VIEW
The picture changes. Your mission stays in focus.
Illustrative display · Not live equipment or operational scoring.
06 / THE CONNECTED PICTURE
Context, a clear comparison and a result you can understand. Explore the perspective PD is being developed to bring.
01 / CONTEXT
Keep the mission question and available information visible.
