From my vantage point, few areas are evolving as rapidly and with such profound implications as the space sector. For decades, satellites were essentially fixed hardware – powerful, expensive, but ultimately immutable once launched. That paradigm is undergoing a transition driven by Software-Defined Satellites (SDS). A recent market study by ABI Research underscores this transition, painting a picture of technological advancement and a fundamental reshaping of global connectivity, security, and national interests. LEO SDS Market Development The core concept behind SDS is deceptively simple yet revolutionary: decouple the satellite's capabilities from its physical hardware. Instead of launching a satellite designed for a single, fixed purpose (like broadcasting specific frequencies to a specific region), SDS allows operators to modify, upgrade, and reconfigure a satellite's functions after it's in orbit, primarily through software updates. The ABI Research report highlights ...
