How can I know the coordinates that the aircraft has moved along the path. If i don't know the position and direction?

I understand that speed, time, and the direction and position of the aircraft are necessary to make an aircraft move. But if we only know the direction and position of the aircraft at first, how can I know the coordinates that the aircraft has moved along the path if we don't know the position and direction?

Please let me know.

If you do not know the speed or time of movement, then you cannot know the position at any time after the initial conditions.

Consider the possibility that the plane is pointed due east at time 0 and position the equator at longitude 0. 1 minute later the plane could be anywhere along the equator, because the speed could be anywhere from negative infinity to positive infinity.

First of all, thank you for your response. The speed is 50m/s, the first direction of the rider is 0 degrees based on the azimuth, and the time is set to dt=0.1s. In this situation, can the aircraft pull out the coordinates along the path?

It sounds as if you know the speed, direction, and time, but perhaps not the initial position ??
