Abstract:
1. A method for determination of kinematics of a moving object, the method comprising: receiving angular data for the moving object at a plurality of observation times; determining a first kinematic state of the moving object based on the angular data at a first observation time; determining a predicted kinematic state of the moving object based on a kinematic model of the moving object and at least one previously determined kinematic state of the moving object; determining a subsequent kinematic state of the moving object at a subsequent observation time based on the predicted kinematic state of the moving object and the angular data for the moving object, wherein the kinematic model comprises an assumption that the moving object follows a guidance law navigating the moving object to a known position; determining whether the moving object is moving toward the known position; and generating a warning that the moving object is moving toward the known position if it is determined that the moving object is moving toward the known position.
