Space Inventor

Space Inventor is an independent Danish satellite builder founded in 2015 and headquartered in Aalborg, Denmark. It designs and manufactures satellite subsystems, modules and complete platforms in-house, and serves customers and partners in the defence, commercial and scientific sectors. Its site describes the company as a second-generation New Space company working from a satellite constellation factory in Denmark.

Satellite modules

The company's modules are built as scalable building blocks for complete platforms, covering communications, Earth observation and security missions. Product groups include:

• Guidance, navigation and control: reaction wheels, sun sensors, star trackers, magnetorquers, inertial measurement units and GNSS receivers
• On-board data handling
• Satellite antenna systems
• Power management
• Communication subsystems

Satellite platforms

The BIG CAT family of platforms is built from the company's flight-proven modules. The BIG CAT 100 uses a quarter-plate payload adapter, the BIG CAT 300 is an ESPA-class satellite for a half-plate payload adapter, and the BIG CAT 600 is an ESPA Grande-class satellite for a full-plate payload adapter, intended for heavier missions. Space Inventor also offers turnkey satellite solutions and mission services.

Flexible Modularity and production

Space Inventor calls its design philosophy Flexible Modularity: missions are assembled from standardised, flight-proven subsystems while the structure itself can adapt if a payload changes during a project. The company says it manufactures about 95 percent of satellite subsystems in-house, using five-axis CNC machining and automated electronics assembly with full production traceability. Each mission is run by a programme manager, a system engineer and a product assurance lead. The site refers to satellite constellations built for sovereign surveillance over sea and land.
