We present SABAT ("Sapienza" Balloon Trajectory Simulation Code), a Fortran software for the simulation of zero-pressure scientific balloon trajectories at stratospheric altitudes. Particular attention is made to the correct reproduction of the balloon ascending phase to the floating altitude. In order to obtain trajectories in agreement with those monitored during actual balloon launches and flights, SABAT features a balloon dynamical and geometric model, and a thermal model for the heat exchanges between the vehicle and the surrounding environment. In addition, both a synthetic description of the Earth's atmosphere and real data from radiosondes can be used. The validation tests give results in agreement with the characteristics of real balloon motion. Future developments of the code include optimization for balloons flying at polar latitudes, an improved treatment of the drag force acting on the balloon structure and the development of a user-friendly graphical interface.

Abstract

We present SABAT ("Sapienza" Balloon Trajectory Simulation Code), a Fortran software for the simulation of zero-pressure scientific balloon trajectories at stratospheric altitudes. Particular attention is made to the correct reproduction of the balloon ascending phase to the floating altitude. In order to obtain trajectories in agreement with those monitored during actual balloon launches and flights, SABAT features a balloon dynamical and geometric model, and a thermal model for the heat exchanges between the vehicle and the surrounding environment. In addition, both a synthetic description of the Earth's atmosphere and real data from radiosondes can be used. The validation tests give results in agreement with the characteristics of real balloon motion. Future developments of the code include optimization for balloons flying at polar latitudes, an improved treatment of the drag force acting on the balloon structure and the development of a user-friendly graphical interface.
