HPS wins German government space competition with ADEO deorbit sail

November 2023

Space sails from the ADEO series enable legal launch and disposal of satellites

As part of the National Program for Space and Innovation and based on the decision of the Budget Committee in November 2022, the German Space Agency launched a competition for promising space innovations. The winner can expect a fully organized and financed demonstration flight with launch by 31.12.2025. On Thursday, 23 November 2023, the Federal Government’s Space Coordinator, Dr Anna Christmann, selected Munich-based space technology company HPS as the winner of the competition in the small satellite payload category with its ADEO-Cube space sail version at the 2023 Small Satellite Conference. The ADEO product family is designed as a series with different model types (Pico, Cube, Nano, Medium, Large), with which all satellites from the Cubesats to the larger representatives with 1.5 tons (class “M”) are automatically removed from low Earth orbit (LEO) and disposed of at the end of the mission. This so-called “deorbiting” with the ADEO braking sail not only fulfills, but even undercuts the maximum duration of 5 years that will apply from October 2024 instead of the 25-year guideline that has been in place since the 1960s. Quite simply, this means that no satellite will soon be accepted for launch without special on-board technology, such as the appropriate space sail from HPS’s ADEO series, if it cannot otherwise be legally disposed of. Since SpaceX, for example, as the leading launch service provider, will be introducing this rule from October 2024, it will apply to practically all future satellites, including those that are already in the design and manufacturing phase today.
As HPS CEO Ernst K.Pfeiffer, there is still only one alternative to ADEO, but it “is chemical, expensive and – in the case of a damaged satellite – inoperable”, the passionate aerospace engineer states about the market position of the ADEO space sail: “ADEO is currently the cheapest, most reliable and cleanest solution for legal deorbiting on the global market, available in all classes thanks to series production at HPS Bucharest and HPS Munich, and highly competitive in the hotly contested commercial market for satellite technology.We at HPS, especially our development team, are all very pleased that our sustainable technology has been recognized by the Small Satellite Competition at the highest level.”
