- Abstract
- This paper presents a robust wind estimation scheme for a simple tethersonde system, which is to use a commercially available radiosonde for recalibration and recovery. A radiosonde system determines wind speed and direction by keeping track of the radiosonde’s position as it rises. However, the method used in the radiosonde system is not suitable for the tethersonde system due to tethering to the ground. Hence, the proposed scheme introduces a drag force caused by the movement of the tethersonde to estimate the wind speed. This paper also evaluates the scheme through simulation in terms of wind speed estimation. Simulation results show that a radiosonde can be utilized as a tethersonde for the low and middle atmospheric observation without modification.
