Abstract : A comparison of winds obtained using a Loran radiosonde system developed at Phillips Laboratory and winds derived using radar tracking of targets attached to the radiosonde balloon train are presented. The tests involve 10 ascents with dual Loran ground stations on most flights and dual radar tracking on two flights. The tests were performed at the Goddard Space Flight Center/Wallops Flight Facility in June 1990. The radiosonde is sufficiently accurate (0.32 m/s) to evaluate a wind profiler that has an error budget of 1.0 m/s. The wind profiler has been proposed to satisfy Day of Launch missile range wind measurement requirements.
