The fundamental rules of ISO/GPS

44、 given in ISO 8015 apply to this document and the default decision rules given in ISO 14253-1 apply to the specifications made in accordance with this document, unless otherwise indicated.For more detailed information of the relation of this document to other standards and the GPS matrix model, see
