GB/T 17424-2019Technical requirements of differential global navigation satellite system (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 17424-2009 "Difference Global Navigation Satellite System (DGNSS) Technical Requirements". And GB/T 17424-

Compared with.2009, the main technical changes except editorial changes are as follows.

--- Revised scope (see Chapter 1, Chapter 1 of the.2009 edition);

--- Revised the normative reference document (see Chapter 2, Chapter 2 of the.2009 edition);

--- Removed 8 terms (see Chapter 3 of the.2009 edition) and added 8 terms (see Chapter 3);

---Modified the basic structure of the system (see Chapter 4, Chapter 4 of the.2009 edition);

--- Revised the site selection of the broadcaster (see Chapter 5 of the.2009 edition) and incorporated it into the broadcaster (see Chapter 5.2 of the 5.2,.2009 edition);

---Modified technical requirements (see Chapter 5, Chapter 6 of the.2009 edition);

--- Revised the general requirements (see 6.1 of the.2009 edition), some of which were moved into Chapter 8 (see 5.1, 8.10);

--- Modified the GNSS receiver requirements for the reference station (see 5.2, 6.2 of the.2009 edition);

--- Increase control center requirements (see 5.3);

--- Combine DGNSS technical characteristics into RBN-DGNSS emission characteristics (see 8.1, 8.2, 8.3, 8.4, 8.5, and 8.6,.2009 edition)

6.3);

--- Increase the general DGNSS receiver requirements (see 5.4.1);

--- Revised the technical requirements for shipborne radio beacon receivers (see 5.4.2.1, 5.4.2.3, 5.4.2.4, 5.4.2.5 and 5.4.2.6,.2009)

Version 6.4);

---Modified message types 3, 4 and 27 (see 6.2.3, 6.2.4 and 6.2.10, 7.4, 7.5 and 7.15 for.2009);

--- Increased message types 15, 37, 41, 42 and 43 (see 6.2.8, 6.2.16, 6.2.17, 6.2.18 and 6.2.19);

---Modified the message broadcast process (see Chapter 7, Chapter 8 of the.2009 edition);

--- Modified coastal radio DGNSS (RBN-DGNSS) emission characteristics (see 8.2, 8.3, 8.4, 8.6, 8.9, 8.10, 8.13,.2009 edition)

Chapter 9).

This standard uses the redrafting method to refer to ITU-R M.823-3.2006 "Marine radio beacons in Zone 1 to 283.5kHz~

Technical characteristics of the 315 kHz band and the transmission of differential GNSS data in the 2, 3 zone from 285 kHz to 325 kHz, with ITU-R

The degree of consistency of M.823-3.2006 is non-equivalent.

1 Scope

This standard specifies the basic composition of the Differential Global Navigation Satellite System (DGNSS), the location of the broadcast station, technical requirements, message format and electricity.

Text type, message broadcast process and coastal radio beacon - differential global satellite navigation system launch characteristics.

This standard applies to the design, development and use of water DGNSS broadcasters and receivers.
