Paper Abstract

Aimed at wind measurement requirement of pilot balloon observation, the double-theodolite base-line method will be discussed mainly. Then based on GJB6076-2007 and GJB 6556.3-2008, the formulas of wind vector were given and the error propagation model of double-theodolite wind measurement was founded. At last, the system and random errors of some wind measurement data were calculated and analyzed. The results showed that, the error of the double-theodolite method was mainly caused by the elevation and the azimuth angles, including measurement error and tracking error. It increases rapidly with time and height increase, and can be remarkably reduced if the error of balloon tracking is removed.
