Description
Returns the 2D probability of collision (Pc) between the primary Spacecraft and secondary Spacecraft, using the RIC Covariances provided as arguments.
Timing Precision Mode
This page describes functionality in millisecond timing precision mode. Millisecond timing precision mode is deprecated and will be removed in a future release. We recommend that you migrate your Mission Plans to nanosecond timing precision mode.

Method Signature
Arguments
Spacecraft
|
|
Description:
|
The secondary object of the conjunction.
|
PrimaryCovariance
|
|
Description:
|
A 9 element array containing the position covariance of the primary object, given in the spacecraft RIC frame with units of m^2.
|
Required Size:
|
9
|
SecondaryCovariance
|
|
Description:
|
A 9 element array containing the position covariance of the secondary object, given in the spacecraft RIC frame with units of m^2.
|
Required Size:
|
9
|
HardBodyRadius
|
|
Description:
|
The Hard-Body 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 Hard-Body Radius is equal to half the side-length of the Square.
|
Units:
|
m
|
Valid Range:
|
HardBodyRadius > 0
|
RelativeErrorTolerance
|
|
Description:
|
The Relative Error Tolerance to be used for integrating the Gaussian distribution.
|
Valid Range:
|
RelativeErrorTolerance > 0
|
Return Value
Returns the 2D probability of collision (Pc) at the time of closest approach (TCA).
Syntax
