Abstract:
1. A method of estimating a trajectory of a moving body in a real navigation environment, including a digital simulator tool that is modeling the moving body in this environment supplying kinematics commands to a movement simulator on which the moving body is mounted and to a target representative of an objective to be reached by the moving body, said digital simulator tool being fed with piloting commands delivered by a computer of said moving body and, in response to these piloting commands, delivering points of the trajectory, said estimation method further including: on detection of an event representative of overshooting or changing a first designated objective for the moving body, performing a positioning associated with a second designated objective for the moving body, the positioning including: if the first and second markers are activated, evaluating a difference between the current kinematics command supplied to the movement simulator and the current kinematics command supplied to the target by the digital simulator tool; and if this difference is below a particular threshold, performing a piloting including applying corrective terms linked to said setpoint positions to the kinematics commands coming from the simulator tool before they are fed to the movement simulator and to the target.
