Abstract : The effect of crosswind on the dispersion of the 5 in. HARP probe has been investigated theoretically. Calculated wind corrections have been applied to the azimuth at apogee for a series of firings at Wallops Island, Virginia. These results indicate a mean deflection at apogee of less than 0.5 degrees. An estimate of wind effect on the impact of vertically launched probes is also given. (Author)
