Orbital Debris Collision Risk Calculator

Orbital Debris Collision Risk Calculator estimates the probability of collision between a satellite and space debris based on orbital parameters, debris density, and satellite characteristics.

How to Use:

1. Enter the satellite’s orbital altitude and inclination.
2. Specify the satellite’s cross-sectional area and mission duration.
3. Select the orbit type for typical debris density values.
4. Click “Calculate Collision Risk” to estimate collision probability.
5. View the collision probability, debris density, and other risk metrics.
6. Analyze the risk classification and mitigation recommendations.

Formulas Used:

Collision Probability Formula:

\( P = 1 – e^{-n \cdot \sigma \cdot v \cdot t} \)

Where:
\( P \) = collision probability
\( n \) = debris number density (pieces/km³)
\( \sigma \) = collision cross-section (km²)
\( v \) = relative velocity (km/s)
\( t \) = time duration (seconds)

Orbital Velocity:
\( v_{orbital} = \sqrt{\frac{GM}{R + h}} \)

Where:
\( G \) = gravitational constant
\( M \) = Earth’s mass
\( R \) = Earth’s radius
\( h \) = orbital altitude

Typical Risk Classifications:
• Low Risk: < 1% probability
• Medium Risk: 1-5% probability
• High Risk: > 5% probability
