The GNSS track angle
is defined as a measurement of the direction a vehicle moving in, which also determines average velocity .
In addition, aircraft track angle [[theta].sub.M] is adopted in the paper as controlled variable.
Since the assumed target in one time domain is free of maneuvering, [[??].sub.tp] can be obtained easily; [t.sub.tp] refers to the estimated remaining time of target without maneuvering; [q.sub.tfn] indicates that the track angle of UAV in receding horizon reaches the angles prospected.

I would also recommend changing the WPT field to TKE (Track Angle
It has a +30-degree detection/ track angle
in azimuth and two or four bars in elevation.
Although track angle
error (TKE) has some benefits, cross track error (XTE), in my opinion, beats it hands down.
The track angle
error (TKE) field of Garmin 400/500 navigators is just such a diamond in the rough.
However, I'm surprised he didn't mention using a feature on the popular Garmin GNS 400/500 series of GPSs called Track Angle
Error, or the TKE, on the map screen.
* Measuring the speed of the car with different track angles
Lots of people can draw circles, lines, and boxes but there are not very many people in the business that can track angles
and distances as they change and actually be able to tell how far somebody actually runs or how deep a person gets in a squat."
