BIG CAT 600
COMPLETE ARCHITECTURAL FREEDOM FOR HEAVY-DUTY MISSIONS
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 – whether for Earth observation, advanced communications, or complex technology demonstrations.
Built to Endure Featuring standard, fully redundant, and radiation-tolerant avionics, the BIG CAT 600 is designed for operations with a lifespan of up to 7 years across LEO, MEO, and GEO. Its architecture adheres to ECSS guidelines, with advanced mitigations for single-event effects to ensure your mission stays secure in the harshest environments.
Mission-Ready Power Power your payloads with confidence. The platform features deployable solar panels and storage capacity of up to 1000 Whr, delivering more than 500 W of continuous power to support your power-intensive applications.
Seamless Precision & Propulsion 3-axis active attitude control achieves a pointing accuracy of 10 arcsec (1σ) supported by star trackers, fine sun sensors, and gyroscopes. With multiple control modes – including nadir pointing, inertial, ground spot tracking, and scanning – and a hybrid chemical and electric propulsion system, the BIG CAT 600 ensures efficient orbit maintenance and maneuverability.
Intelligent Data & Connectivity Data flows through dedicated and standard payload interfaces, including Ethernet, LVDS, and SpaceWire. A reliable S-band communication architecture secures your critical ground link, while available X- and Ka-band options secure efficiently downloaded payload data.
