ActiveSpace data and information transfer systems—Proximity space link protocol—Synchronization and coding sublayer
空间数据与信息传输系统 邻近空间链路协议 同步和编码子层
Application Summary AI generated
GB/T 39353-2020 specifies the synchronization and coding sublayer for proximity space link protocols, defining data framing, error correction coding, and synchronization mechanisms for short-range spacecraft communications. It is applied in space missions involving orbital rendezvous, lander-to-orbiter links, or inter-satellite data transfer within close proximity (e.g., within a few kilometers). This standard ensures reliable, low-latency data exchange between spacecraft in formation flying, docking, or surface exploration scenarios.
