I discovered uavParam variable which has several fields (at least two: uavParam.ic.Pos_0 - for initial position probably and uavParam.ic.gsLL). It is located inside Waypoints constant vector - the input of UAV Waypoint Follower block in this mathworks example (pathFollowing.slx; 5x3 by default; left side of a screenshot inside). I understand that this vector is for our desired points in the path. But what is this "uavParam" for and where can i find any documentation about this? At least which fields does this uavParam have?
Didn't find anything even inside simulink example (also tried ctrl+f and typed uavParam).
