标准摘要
[中文适用范围]： 本推荐标准定义了透明和再生PN测距系统，适用于非数据中继卫星用户。该文档规定了PN码组件和生成、航天器上透明/再生处理、地面站处理以及上行链路和下行链路信号调制的规范。本推荐标准未指定：a)个别实现或产品；b)实际系统内服务接口的实现；c)配置和控制协议所需的管理活动。 [外文原描述]： ISO 18423:2015 defines both transparent and regenerative PN ranging systems for non?data relay satellite users. The specification for PN code components and generation, on-board spacecraft regenerative/transparent processing, ground station processing, and uplink and downlink signal modulation are defined in this document. This Recommended Standard does not specify a) individual implementations or products, b) implementation of service interfaces within real systems, or c) the management activities required to configure and control the protocol.
