ToolAssay

Propagates two caller-supplied Cartesian states with constant velocity, analytic

Propagates two caller-supplied Cartesian states with constant velocity, analytically finds the clamped time of closest approach, and compares miss distance with combined hard-body radius. It ignores gravity, covariance, maneuver uncertainty, tracking error, and nonlinear dynamics and is not an operational conjunction assessment.
