BIG CAT 100

MAXIMUM AGILITY FOR MISSION-SPECIFIC EXCELLENCE

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.

Built to Endure Featuring standard, fully redundant, and radiation-tolerant avionics, this platform is designed for missions with a lifespan of up to 7 years across LEO, MEO, and GEO. Its robust architecture includes advanced single-event mitigations based on ECSS guidelines, ensuring your mission stays securely on track.

Mission-Ready Power The electrical power system provides a continuous orbital average power of 120 with up to 400 W peak. Configure your energy capture with body-mounted, single, or double deployable solar panel options to match your orbital profile.

Seamless Precision & Propulsion The BIG CAT 100 delivers 3-axis attitude control with pointing knowledge of < 16 arcsec using star trackers across multiple default pointing modes, supported by star trackers, fine sun sensors, and gyroscopes Baseline electric propulsion ensures you are fully equipped for seamless orbit/de-orbit transfers and proactive collision avoidance.

Intelligent Data & Connectivity Data flows through a standard CAN with CSP 2.0 avionics communication layer, supported by RS-422 and high-speed interfaces including Ethernet, LVDS, and SpaceWire. Baseline S-band RF keeps you securely connected to the ground segment, while available X- and Ka-band links allow for rapid, high-volume payload data downloads. If your mission requires something unique, custom data interfaces are always available on demand.
