A code for the analysis of missions with electrodynamic tethers

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