A computerized method of vector triangulation for determination of horizontal wind profiles and shear in the stratosphere is described. Positions in photographic images of sunlight-scattering smoke trails released from rockets are automatically recorded by a digital video densitometer operating in an on-axis mode, from which three-dimensional positions are obtained. Requirements for accuracy of location and 3-axis orientation of the triangulation cameras, needed to provide 10 meter altitude accuracy, are outlined. A logic design for a new generation hardware system is presented. Author
