Method Signature
Arguments
Spacecraft


Description:

The secondary object of the conjunction.

PrimaryCovariance


Description:

A 3x3 matrix containing the position covariance of the primary object, given in the spacecraft RIC frame with units of m^2.

Required Size:

3 x 3

SecondaryCovariance


Description:

A 3x3 matrix containing the position covariance of the secondary object, given in the spacecraft RIC frame with units of m^2.

Required Size:

3 x 3

HardBodyRadius


Description:

The HardBody Radius to be used for the conjuncting objects, given in units of meters. This argument is a combination of the hard body radius for both the primary and the secondary objects. When the ShapeType is set to Square, the HardBody Radius is equal to half the sidelength of the Square.

Units:

m

Valid Range:

HardBodyRadius > 0

Return Value
Returns the 2D probability of collision (Pc) at the time of closest approach (TCA).
Syntax
myVariable1 = mySpacecraft1.ProbabilityOfCollision(mySpacecraft2, myMatrix1, myMatrix2, myVariable2);
