The PPDH-110 by Azista USA is a highly modular payload power and data handling system designed for small satellites and advanced payloads. Serving as a single interface unit between the satellite bus and payload, it ensures seamless power management, telecommand (TMTC) forwarding, and payload data routing. The PPDH-110 is space-qualified and flight-proven, making it an essential component for responsive space missions in Earth observation, defense, and commercial applications.
Versatile Power Conditioning – Supplies regulated DC voltages (1.8V to 40V), overcurrent protection, and payload time synchronization
Reliable Data Handling – RS422 & LVDS interfaces, payload telemetry collection, and fault protection against latch-ups
High Modularity – Easily adaptable to new payloads while keeping the satellite bus unchanged
Flight-Proven Design – Space heritage validated for LEO missions with a 5-year design life
