Scope

GB/T 48025-2026 is the English-translated version of 地基导航卫星遥感水汽和电离层探测系统.

GB/T 48025-2026 covers ground-based systems that use satellite navigation signals to sound atmospheric water vapour and the ionosphere.

It describes how such a system is composed and specifies technical requirements for appearance and structure, system functions, overall performance, the receiver processing unit, the antenna and the meteorological measurement unit, each with its test method.

It also sets the inspection rules, with type approval and factory inspection, and the requirements for labelling, packaging, transport, storage and the instruction manual.

It applies to the development, production and testing of these systems and refers to GB/T 33700 on ground-based GNSS water vapour observation and to GB/T 44066 on automatic weather stations. It was issued on 30 July 2026 and applies from 1 February 2027.
