Collision Avoidance Manoeuvres
Contents
Manoeuvre Strategies & Operational Considerations
How to choose how to manoeuvre? The most practical approach should be chosen under operational considerations (what if the manoeuvre fails part way? Will the risk of collision be increased?). The manoeuvre strategy should either:
- Maximise displacement at time of closest approach (using b-plane projection)
- Minimise the probability of collision
The collision avoidance manoeuvre (CAM) may be implemented through different control strategies:
- High thrust (~ impulsive manoeuvre, see [1] for analytical model for impulsive CAM)
- Low thrust (more fuel efficient, requires a parametric study of how far in advance and for how long the manoeuvre should be performed)
- Passive (e.g. solar sails [2])
