No... in the case where you're moving in a single direction, you would use the maneuvering board approach. You plot all bearing observations from a central point, to determine relative motion (RM) and then you add your own motion vector to the RM vector to determine target true course.
The only issue in that case has to do with estimating target speed/distance. ...and that's where I begin talking about either a) making an educated guess about speed, or b) predicting future bearings and taking a new observation on a different leg to triangulate the target location. |
Yes .. you need leg or guess. That's exactly what I mean.
