Calibration of a Radome-Differential GPS System on a Twin Otter Research Aircraft for Turbulence Measurements

A five-hole radome pressure probe at the nose of a small two-engine newly instrumented research aircraft was combined with global positioning system (GPS) receivers in differential mode to obtain high frequency measurements of the wind vector in the atmospheric boundary layer with possible accuracy...

Zusammenfassung:A five-hole radome pressure probe at the nose of a small two-engine newly instrumented research aircraft was combined with global positioning system (GPS) receivers in differential mode to obtain high frequency measurements of the wind vector in the atmospheric boundary layer with possible accuracy (root-mean-square error) of about 0.1 m s(-1). This low cost and simple system can provide wind velocity measurements of sufficient accuracy to estimate turbulent fluctuations.
