A windborne vehicle is attached to one end of a tether line which is secured to a tether mast. The tether mast is secured to a ground anchor mechanism for rotative freedom about a vertical axis. The tether line is guided along the tether mast to align the tether mast with the line when the windborne vehicle is in flight. An angle sensing mechanism is effective to measure the azimuth angular displacement of the tether mast around the vertical axis with respect to a fixed reference alignment. A tether line tension sensing mechanism is used to measure the tension force on the tether line. Signals proportional to the angular displacement and the tension force are transmitted to a remote receiving station from the sensing mechanisms. Several different embodiments of the basic assembly show various uses of the invention.
