The main novelties and capabilities of the second version of the Bare Electrodynamic Tether Mission Analysis Software (BETsMA v2.0) are presented. Recent advances on Orbital-Motion-Theory have been incorporated to the electric model of Low-Work-function Tethers (LWTs). An electric model that considers a switch to embed a power supply or a resistor between a Bare Electrodynamic Tether (BET) and an electron emitter is also introduced. For both types of tethers (LWT and BET) and modes of operations (active and passive), robust and efficient numerical algorithms to compute the current and voltage profiles were constructed based on a change of variable proposed in a previous work. The capabilities of the code are illustrated by considering two relevant scenarios. For a BET in the passive mode, it was shown that onboard power can enhance tether performance and reduce significantly the deorbit time. For a BET in the active mode, a performance map varying the orbit inclination, the length of the insulated tether segment, and the power was constructed. For both cases, the code was used to investigate through simulations the conditions to keep constant the electric current at the electron emitter.

介绍了第二版裸电动系绳任务分析软件 (BETsMA v2.0) 的主要新颖性和功能。轨道运动理论的最新进展已被纳入低功函数系绳 (LWT) 的电模型中。还介绍了一种电气模型，该模型考虑在裸电动系绳 (BET) 和电子发射器之间嵌入电源或电阻器的开关。对于两种类型的系绳（LWT 和 BET）和操作模式（主动和被动），基于先前工作中提出的变量变化构建了计算电流和电压曲线的稳健且高效的数值算法。通过考虑两个相关场景来说明代码的功能。对于被动模式下的 BET，结果表明，机载电源可以提高系绳性能并显着减少离轨时间。对于处于主动模式的 BET，构建了一个改变轨道倾角、绝缘系绳段长度和功率的性能图。对于这两种情况，代码都用于通过模拟研究保持电子发射器电流恒定的条件。
