FEATURED ON ESA WEBSITE – Seven ways to use a CubeSat swarm

Earlier this year, European Space Agency (ESA) asked for innovative ideas for new mission concepts enabled by CubeSat swarms. The open call for ideas was run by the Preparation element of ESA’s Basic Activities through the Open Space Innovation Platform (OSIP). The call was answered no less than 61 times. Seven ideas were selected based on an evaluation by a panel of ESA experts, who scored the ideas on their novelty, technological feasibility, and the relevant experience of the submission team.

Sirin Orbital Systems AG is thrilled to have been selected in this campaign with its 16U4SBSP mission concept, “a CubeSat swarm beaming down solar power”; a project developed in cooperation with TU Delft in the Netherlands and the University of Strathclyde in Scotland.

Sirin Orbital Systems AG filed a patent application for an “AI-based vision system for autonomous navigation to space targets”, an invention generally applicable to the field of visual servoing systems for On-Orbit Services (OOS) such as Active Debris Removal (ADR) missions. The intended smart camera uses at an Artificial Intelligence (AI) model to provide target position and orientation information for autonomous navigation to this target in space. This invention is the outcome of an ESA-funded Study in cooperation with the Competence Centre Intelligent Sensors and Networks at the Lucerne University of Applied Sciences and Arts (HSLU).

A follow-on Early Technology Development activity for prototyping and technology readiness enhancement is envisaged.

WINNING ESA CAMPAIGN — “Innovative Mission Concepts Enabled by Swarms of CubeSats”

Sirin Orbital Systems AG wins the European Space Agency (ESA)’s Contract in the “Innovative Mission Concepts Enabled by Swarms of CubeSats” campaign. For this competitive campaign, 74 European entities or individuals generated 74 ideas, 61 of which were carefully evaluated by ESA experts and 13 ideas were chosen for a full proposal phase, after a thorough evaluation. 5 to 7 contracts were awarded at the end.

The “Innovative Mission Concepts Enabled by Swarms of CubeSats” campaign seeks to explore new possibilities in space exploration and Earth observation by leveraging the power of CubeSat Swarms to enable unprecedented scientific and technological advancements.

Sirin Orbital Systems AG and its two Subcontractors, TU Delft in the Netherlands and University of Strathclyde in Scotland, proposed a novel mission concept entitled, “Swarms of CubeSats for kW-scale Space-Based Solar Power (16U4SBSP)“.

The mission concept “16U4SBSP” intends to demonstrate the use of a Swarm of 16U CubeSats for the realization of Space-Based Solar Power (SBSP). The intended mission can supply wireless electricity for space-to-space commercial applications or for space-to-ground purposes. In the proposed demonstration mission, a swarm of CubeSats collaboratively supply a kW-scale power to clients and end-users in different locations, e.g. in-orbit power supply to data-centres or other in-orbit modules with auxiliary power requirements or remote/strategic areas on Earth’s surface. This mission concept is a fundamental technology demonstration step for the realization of GW-scale SBSP, aimed to provide clean and limitless energy from space through wireless power transmission toward the middle of the 21st century. Nonetheless, the original GW-scale SBSP requires large-scale transportation and robotics for the construction of km-scale infrastructure in space, whereas the proposed 16U4SBSP mission can be realized cheaper, faster and easier in a shorter term.

Sirin Orbital Systems AG launched the early technology development phase for its innovative series of water/metal-powder micro-propulsion systems for small satellites. Gratefully supported by the Propulsion Section at the European Space Agency (ESA), the activity was kicked off on the 1st of May 2023 aiming at enriching the technology readiness level up to TRL4 within a 15-month project, when it will be then followed up and de-risked through a GSTP-6 Element I “Develop” activity, already endorsed by the National Delegation to ESA.

The project is realized in cooperation with the Zürich University of Applied Sciences (ZHAW), and receives technical supports from the Space Propulsion Lab at the University of Tokyo.

Sirin Orbital Systems AG supports – as a member of the Space Energy Initiative (SEI) – UK’s plan for the development of Space Based Solar Power (SBSP).

The Space Energy Initiative is bringing together government, research and industry in the space and energy sectors to develop and deliver a co-ordinated programme of technology development and demonstration for the realization of SBSP. Meeting the timeline set out by the UK Government’s Net Zero pledge, and in partnership with other nations, the aim is to establish the first orbital demonstrator SBSP system by 2030, with the first of a kind operational system delivering power into the grid by 2040. A constellation of Solar Power Satellites would be in operation by the mid 2040s, delivering a substantial proportion of the UK’s energy needs.

Sirin Orbital Systems AG will contribute to SEI with its expertise in the field of Wireless Power Transfer (WPT), a key enabling technology for the realization of SBSP.

Sirin Orbital Systems AG was featured in an article published in, entitled “Tinkering for waste collection in space“, describing the R&D efforts at Lucerne University of Applied Sciences and Arts (HSLU), which is performed in cooperation with Sirin Orbital Systems AG. The project was initiated in early summer 2020, within a fruitful internal cooperation supported by Tokyo University of Science (TUS) and NIKON CORPORATION in Japan.

In this joint R&D effort carried out at The Competence Centre Intelligent Sensors and Networks (CC ISN) at HSLU, the development of a smart processor board that provides the possibility for real time detection and classification of space objects based on video image streams from a 2D matrix camera is investigated. A follow-on feasibility study is currently being carried out with the support of the European Space Agency, ESA Initial Support for Innovation (EISI). The final product is aimed to be a fully automated space-qualified camera for space objects detection and classification, with diverse applications such as active debris removal (ADR) missions.
