Description
Returns the 2D probability of collision (Pc) between two objects. Each object must be propagated to the time of closest approach (TCA). The 2D method assumes a high relative velocity and linear relative motion. Note, FreeFlyer uses Foster's 1992 method, in Cartesian coordinates, to compute the Probability of Collision.
For more information on Foster's 1992 method, please refer to: Foster's journal paper "A Parametric Analysis of Orbital Debris Collision Probability and Maneuver Rate for Space Vehicles" from August of 1992.
