GB/T 42644-2023

This standard specifies the Bundle Protocol for space data and information transfer systems, defining how data bundles are formatted, routed, and delivered across delay-tolerant networks in deep-space or long-latency communication environments. It is applied in spacecraft, satellite constellations, and interplanetary missions where intermittent connectivity and high signal delays require store-and-forward data transmission. The protocol ensures reliable end-to-end communication for scientific data, telemetry, and command operations in aerospace and space exploration contexts.
