Innovative Space-Based Computing

The Three-Body Computing Constellation represents a significant shift in data processing methodology. Traditionally, satellites collect raw data and transmit it back to Earth, limited by narrow bandwidths and transmission windows. This new approach aims to process data directly in space, reducing data loss and processing delays 1
