Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1.Structure and drafting rules for standardization documents" Drafting is required. This document replaces GB/T 18314-2009 "Global Positioning System (GPS) Measurement Specification" and is consistent with GB/T 18314-2009. In addition to structural adjustments and editorial changes, the main technical changes are as follows. The name of the standard is changed to "Global Navigation Satellite System (GNSS) Measurement Specification"; a) Add three terms. "GNSS network", "independent baseline" and "point observation mode" (see 3.8, 3.10 and 3.13); b) Added common measurement requirements for multi-satellite systems, added provisions and descriptions for measurements using the BeiDou satellite navigation system (see 4.1, 10.1.2); c) The basic parameters of the reference ellipsoids of the 1980 Xi'an coordinate system and the 1954 Beijing coordinate system have been deleted (see 4.4 of the.2009 edition, Appendix Record A); d) Added the content of using the mean error of the point position to divide the accuracy level (see 5.3.2); e) Some technical details in site selection and stone burial have been modified (see Chapters 7 and 8, Chapters 7 and 8 of the.2009 edition); f) Added the calculation formula for the error in baseline measurement (see 12.2.5); g) Modified some technical details in the technical summary (see 12.7, 12.7 of the.2009 edition); h) Modified some contents of the acceptance of results (see 13.1, 13.1 of the.2009 edition); i) The examples of point marks and some types of landmarks have been changed (see Appendix B, Appendix B of the.2009 edition); j) The calculation content of the centrifugal element was changed and merged with the determination method (see Appendix E, Appendix E of the.2009 edition); k) Added the verification method when the synchronous loop closing error is 0 (see Appendix F). l) Please note that some of the contents of this document may involve patents. The issuing organization of this document does not assume the responsibility for identifying patents. This document is proposed by the Ministry of Natural Resources of the People's Republic of China.
