Mission Analysis Software for Space Systems Deorbiting

Overview

BETsMA (Bare Electrodynamic Tether Mission Analysis) is software for the analysis of missions with electrodynamic tethers. Users provide basic mission data: spacecraft mass, orbits, and the objective to be achieved with the electrodynamic tether (EDT), such as deorbiting, reboost, station-keeping, or power harvesting. Beyond the optimal tether configuration (cathode technology and tether dimensions), BETsMA v2.0 returns a full set of results: evolution of orbital parameters during the mission, electrical variables, forces, tether dynamics and thermal behavior, and safety considerations. The suite is also a strong research tool: it can simulate three electrodynamic tether types (bare, low-work-function, and bare-photovoltaic) with different dynamic models (point-like, multi-bar, and multi-particle) across a wide range of propulsive and power-harvesting scenarios. It delivers high-fidelity modeling of tether dynamics, plasma interactions, and orbital mechanics in low Earth orbit (LEO).
