BETsMA v2.0
Our Mission Analysis Software
Software for the analysis of missions with electrodynamic tether. The users provide basic data about their needs like spacecraft mass, orbits and objective to be achieved by using the electrodynamic tether (deorbiting, reboost, station-keeping and power harvesting).
Besides providing the optimal tether configuration (cathode technology and tether dimensions), BETsMA v2.0 provides a comprehensive set of results that include the evolution of the orbital parameters during the mission, electrical variables, forces, tether dynamic and thermal behaviour, and safety consideration.
The software is also a powerful tool for research because it can simulate three types of electrodynamic tethers (bare, low-work-function and bare-photovoltaic), with different dynamic models (point-like, multi-bar and multi-particle), and in a plethora of propulsive and power harvesting scenarios.
Miram
Our Autonomous device to deorbit satellites
With a mass of 20 kg and a volume of 12 U, Miram is an autonomous device to effectively deorbit satellites, launcher upper stages and payload adapters. The product can be customised to give service to heavy space debris (from hundreds of kg to tons).
After mission completion, Miram is activated from the ground. It detumbles the customer and deploys an electrodynamic tether. The deorbit manoeuvre is completed within a few months, thus reducing strongly the area-time product. Miram is fully autonomous device with telemetry, telecommand and collision probability capabilities.
In the framework of the E.T.PACK and E.T.PACK-F projects, the critical hardware of Miram has been developed and an in-orbit demonstration is scheduled in 2026. PERSEI is taking advantage of such a strong heritage to prepare a product aligned with the needs of the space sector and starts its commercialization in 2027.
Algol
Our product for small satellites
With a mass below 5 kg and a volume of 3U, Algol is a propellant-less propulsion device for small satellites.
Using the power provided by the host satellite, and thanks to its short spinning electrodynamic tether and an expellant-less cathode, Algol provides a propulsion force for deorbiting and reboost the satellite.
It has collision avoidance and tether reel-in and reel-out capacities. Since 2024, and in collaboration with other partners, PERSEI is working on the development of the critical technologies of Algol in the framework of the EIC-funded E.T.COMPACT project.
