Collision Avoidance

Automated maneuver planning for upcoming conjunctions. Specify safety distance and timing, get optimized delta-V solution with fuel cost estimates.

🎯

Custom Maneuvers

Full control over delta-V vector in RTN frame (radial, in-track, cross-track). Simulate orbit raising, lowering, inclination changes, and more.

Fuel Cost Analysis

Tsiolkovsky rocket equation calculations with propellant mass, cost estimates, and mass ratio analysis. Factor in satellite mass and Isp.

How It Works

1️⃣ TLE to Keplerian Elements

We fetch the most recent Two-Line Element (TLE) set from Space-Track and convert it to Keplerian orbital elements.

a = (μ / n²)^(1/3)
ν = f(M, e) via Newton's method

2️⃣ Delta-V Application

Delta-V vector is applied in the RTN frame at the current orbital position.

Δv_vec = Δv_R·r̂ + Δv_T·t̂ + Δv_N·n̂
v_new = v_old + Δv_vec

3️⃣ Fuel Cost Calculation

Tsiolkovsky rocket equation calculates propellant mass required.

v_e = I_sp · g_0
Δm = m_0 · (1 - e^(-Δv/v_e))

4️⃣ Orbital State Changes

New Keplerian elements computed from updated position/velocity vectors.

h = r × v
a = -μ / (2·E)

Use Cases

Emergency Collision Avoidance

High-risk conjunction detected. Calculate minimum delta-V maneuver to achieve 5km miss distance 24 hours before TCA.

Orbit Maintenance

Compensate for atmospheric drag in LEO. Small in-track burns to restore semi-major axis and maintain operational altitude.

End-of-Life Deorbit

Calculate delta-V required to lower perigee below 200km for 25-year deorbit rule compliance.

Insurance Underwriting

Assess collision avoidance frequency and fuel costs for mega-constellation satellites.

Assumptions & Limitations

  • •
    Two-body dynamics: Simplified Keplerian mechanics. Does not include J2, drag, or third-body effects.
  • •
    Impulsive burns: Assumes instantaneous delta-V application. Finite burn duration not modeled.
  • •
    Cost estimates: Based on $50,000/kg propellant. Actual costs vary by mission architecture.
  • •
    TLE freshness: Accuracy depends on TLE age. Use recent TLE data (<24 hours) for critical operations.
