+ethodolog": The Theor" Right angled triangle #as used for plotting the actual position of the High +ast and the difference of the actual position and assumed position #as measured measured in the Auto A&. -rom this triangle the horiontal distance and the !ertical angle to the top of the High mast #as measured #ith high precision electronic Total /tation #ith an accurac" of $. The Total /tation #as set up in a suitable place in such a #a" that the !ertical !ertical angle to the top of the mast could be measured measured easil".

This method is repeated three three times and an a!erage of these measurements measurements #ere used to plot the position position of the mast.
