摘要：

我们提出了SABAT（“Sapienza”气球轨迹模拟代码），一个Fortran软件的零压力科学气球在平流层高度的轨迹模拟。特别注意的是，正确再现气球上升阶段的浮动高度。为了获得与实际气球发射和飞行过程中监测到的轨迹一致的轨迹，SABAT配备了气球动力学和几何模型，以及飞行器与周围环境之间热交换的热模型。此外，还可以使用对地球大气层的综合描述和无线电探空仪的实际数据。验证试验给出的结果与实际气球运动的特性一致。该代码的未来发展包括优化在极地纬度飞行的气球，改进对作用在气球结构上的阻力的处理，以及开发用户友好的图形界面。

英文摘要：

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.
