A square Root Unscented Filter (SR-UKF) is used to estimate the states of a receiver aircraft and the components of the wind the is exposed to as it flies behind the tanker aircraft. The wind is the superposition of time-varying prevailing wind, turbulence and the tanker's wake-induced wind. The aircraft state estimates are successfully used in controlling the position of the receiver aircraft relative to the tanker flying straight level and making turns. The performance of the estimation and control is very very dependent on the covariance and correlation time constants of the sensor measurement errors.
