ActiveSpace data and information transfer systems—Licklider transmission protocol（LTP）
空间数据与信息传输系统 利克莱德传输协议（LTP）
Application Summary AI generated
This standard specifies the Licklider Transmission Protocol (LTP) for reliable data delivery over long-delay and disruption-prone space communication links. It is applied in space data and information transfer systems, such as deep-space missions, satellite constellations, and interplanetary networks, where traditional TCP/IP protocols are ineffective. The standard ensures reliable file and message transmission between spacecraft, orbiters, and ground stations under high-latency or intermittent connectivity conditions.
