Codeofchina.com is in charge of this English translation. In case of any doubt about the English translation, the Chinese original shall be considered authoritative. This standard is developed in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the Equipment Development Department of the Central Military Commission. This standard is under the jurisdiction of the Technical Committee on Steel of Standardization Committee of China (SAC/TC 544). General specification for GNSS geodetic receivers onboard low earth orbit satellite 1 Scope This standard specifies the technical requirements, test methods, inspection rules, as well as marking, packaging, Transport and storage of global navigation satellite system (GNSS) geodetic receivers onboard low earth orbit (LEO) satellite. This standard is applicable to the development, production, testing, use and inspection of GNSS geodetic receivers onboard low earth orbit satellite. Other GNSS geodetic receivers for LEO spacecrafts may also be used for reference. 2 Normative references The following referenced documents are indispensable for the application of this standard. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
