标准范围

邻近空间链路被定义为短程、双向、固定或移动无线电链路，通常用于探测器、着陆器、漫游者、轨道星座和轨道中继之间的通信。这些链路的特征是时间延迟短、信号中等（而不是弱）以及短而独立的会话。ISO 21459:2006定义了邻近-1空间链路协议的编码和同步子层。它定义了该子层的数据单元，即PLTU。它定义了交叉支持所需的编码和同步机制。它还指定了该子层的发送端和接收端功能。ISO 21459:2006未规定单个实现或产品、真实系统内服务接口的实现、执行程序所需的方法或技术、或配置和控制协议所需的管理活动。

Proximity space links are defined to be short-range, bi-directional, fixed or mobile radio links, generally used to communicate among probes, landers, rovers, orbiting constellations, and orbiting relays. These links are characterized by short time delays, moderate (not weak) signals, and short, independent sessions.ISO 21459:2006 defines the coding and synchronization sublayer of the Proximity-1 space link protocol. It defines the data unit of this sublayer, i.e. the PLTU. It defines the coding and synchronization mechanisms required for cross support. It also specifies the send and receive side functionality of this sublayer. ISO 21459:2006 does not specify

• individual implementations or products,
• implementation of service interfaces within real systems,
• methods or technologies required to perform the procedures, or
• management activities required to configure and control the protocol.
