Decide if the UAV is approaching the current waypoint.

Computes dist2_to_wp and compare it to square carrot. Return true if it is smaller. Else computes by scalar products if uav has not gone past waypoint. approaching_time can be negative and in this case, the UAV will fly after the waypoint for the given number of seconds.

Returns
true if the position (x, y) is reached

distance to waypoint in x

distance to waypoint in y

Navigation along a figure 8.

The cross center is defined by the waypoint [target], the center of one of the circles is defined by [c1]. Altitude is given by [target]. The navigation goes through 6 states: C1 (circle around [c1]), R1T, RT2 (route from circle 1 to circle 2 over [target]), C2 and R2T, RT1. If necessary, the [c1] waypoint is moved in the direction of [target] to be not far than [2*radius].
