BIG CAT 300
ULTIMATE VERSATILITY FOR HIGH-DEMAND MISSIONSDesigned 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 your unique mission needs.
Built to Endure Equip your mission for the long haul. Featuring standard, fully redundant, and radiation-tolerant avionics, the BIG CAT 300 is designed for operations with a lifespan of up to 7 years across LEO, MEO, and GEO. Its robust architecture adheres to ECSS guidelines, featuring advanced mitigations for single-event effects to ensure mission security.
Mission-Ready Power The platform’s flexible electrical power system provides multiple conditioning options, delivering a continuous orbital average power of 160 W – and surging to over 500 W at peak performance. Options for body-mounted, single, or double deployable solar panels match power capture to your mission requirements.
Seamless Precision & Propulsion 3-axis attitude control offers pointing knowledge of < 16 arcsec using star trackers across multiple default pointing modes, supported by star trackers, fine sun sensors, and gyroscopes. Uniquely designed to accommodate both chemical and electrical propulsion systems, the BIG CAT 300 is fully primed for rapid orbit transfers, agile maneuvering, and proactive collision avoidance.
Intelligent Data & Connectivity Data flows through a standard CAN with CSP 2.0 avionics communication layer, integrated with RS-422 and high-speed interfaces like Ethernet, LVDS, and SpaceWire. Baseline S-band RF secures your critical link to the ground segment, while available X- and Ka-band options facilitate speedy payload data downloads. Alternative data interfaces are always available on demand.
