This July the group delivered a high altitude sonic anemometry system to NASA Wallops Flight Center for integration into a high altitude balloon platform. The system is the latest update to the Tufts Sonic Anemometer and will provide three dimensional relative wind measurements and speed of sound measurements at a rate of just over 4 samples/second. Speed resolution is approximately 10 cm/s. The system will also log infrasound, pressure, temperature, GPS location, and orientation (9 DOF IMU) throughout the flight.
