The ADEO (Drag Augmentation Deorbiting System), developed by HPS, is a scalable product family of deployable drag sails designed to accelerate the deorbiting of satellites and launch vehicle components in low Earth orbit. By increasing atmospheric drag, it passively reduces orbital lifetime without requiring additional propellant or active attitude control, supporting responsible end-of-life disposal and space debris mitigation.

DarKnight is an open-source tool developed by OHB for modelling satellite visual brightness throughout a mission. It simulates sunlight reflections from spacecraft surfaces to predict apparent brightness, supporting the assessment of satellite visibility from Earth. The tool helps engineers evaluate spacecraft designs and mitigate impacts on astronomical observations.

ESA’s Debris Risk Assessment and Mitigation Analysis (DRAMA) is a suite of software tools developed by the European Space Agency to assess space debris risks and support spacecraft design and mission planning. It evaluates debris mitigation compliance, orbital lifetime, re-entry casualty risk, collision risk, and debris-related environmental impacts throughout a mission’s lifecycle.
It includes specialised modules for collision avoidance, impact damage assessment, disposal planning and re-entry safety, helping engineers identify risks and verify mitigation strategies

The International Astronomical Union’s Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference (IAU CPS) coordinates global efforts to mitigate satellite constellations’ impacts on optical and radio astronomy. Co-hosted by NSF’s NOIRLab, the SKA Observatory, and ESO it connects astronomers, industry, policymakers and other stakeholders to develop technical solutions, share information and promote responsible practices

PEARSON is a new-generation autonomous deorbit device that leverages propellant-free electrodynamic tether technology for sustainable end-of-life deorbiting of satellites and launcher upper stages. It will be commercialised by PERSEI Space based on the lessons learned from the E.T.PACK-F deorbit device and its in-orbit demonstration.
