Made in Denmark, for the world
SATELLITE
PLATFORMS
Since our founding in 2015, Space Inventor has grown to become a premier satellite systems integrator – tailoring successful customer projects based on the agility, precision and performance of our flight-proven satellite platforms.
WELCOME TO
THE BIG CAT FAMILY
Today our made-in-Denmark tradition of reliability and innovation is embodied in our Big Cat platforms.
Big Cats are the ultimate manifestation of our in-house, Flexible Modularity approach: standardized platforms conforming with bespoke agility to your payload with higher reliability, superior performance, faster development times, and greater cost efficiency.

BIG CAT 100
Crafted from our in-house, modular equipment and utilizing a quarter-plate payload adapter, the BIG CAT 100 is engineered to deliver unrivaled flexibility. Its agile foundation adapts to your unique and fast-paced mission requirements.
BIG CAT 300
Designed as an ESPA-class satellite for a half-plate payload adaptor, the BIG CAT 300 is engineered from our flight-proven, in-house modules. It delivers a versatile architectural foundation to accommodate a wide range of mission types with speed and quality.
BIG CAT 600
Designed as an ESPA Grande-class satellite for a full-plate payload adapter, our largest platform is built from our flight-proven, in-house modules. The BIG CAT 600 serves as a robust, highly customizable foundation for your most demanding and heavy-duty missions.
Flexible Modularity also means the ability to adapt to changing requirements. If your payload adjusts during the project – so do we. This is the power of being a vertically integrated company: rapid prototyping and drawing from our own in-house production of platforms and modules to modify as needed without relying on 3rd-party suppliers or being subject to costly delays.
DEEP VERTICAL INTEGRATION ENSURES THESE BIG CATS ALWAYS LAND ON THEIR FEET
While vertical integration drives our pioneering innovations, our role as a satellite systems integrator has affirmed our reputation as a partner who offers trust, transparency and predictability. This pioneer+partner approach means we can both reach for the stars and be firmly grounded to manage complete lifecycles – from concept and design to rigorous verification and validation – ultimately reducing risk and keeping your project on schedule and within budget.
This end-to-end offering applies whether it’s Big Cat satellites, turnkey satellite solutions, satellite equipment, or mission services. All are built on a foundation of standardized excellence and maximum agility to launch you further, faster, and more effectively for a wide range of mission applications, including:
COMMUNICATIONS (COMMS)
Scaling power and data handling effortlessly to support high-throughput connectivity.
EARTH OBSERVATIONS (EO)
Providing the ultra-stable pointing accuracy required for high-resolution optical and thermal imaging.
SIGNAL INTELLIGENCE (SIGINT)
Offering interception, collection and analysis of electromagnetic signals.
SPACE SITUATIONAL AWARENESS (SSA)
Delivering the processing power and reliability needed to track and characterize space objects in real-time.
IN-ORBIT DEMONSTRATION (IOD)
Facilitating flight access, technological feasibility and performance.
GEOSTATIONARY ORBIT
Featuring the latest advances in onboard propulsion for manoeuvering from Geostationary Transfer Orbit or even Low Earth Orbit to GEO.
POSITION, NAVIGATION AND TIMING (PNT)
Transmitting stronger signals, reduced latency and greater resilience against jamming and spoofing of GNSS/GPS systems.
