GB/T 13186-2017General specification for airborne Doppler navigation systems (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 13186-1991 "General Conditions for Airborne Doppler Navigation System", compared with GB/T 13186-1991 The main technical changes are as follows:

--- Removed the "indicator" "maintainability" "field replaceable unit (LRU) and infield replaceable unit SRU" three terms and set Justice (see Chapter 3 of the.1991 edition);

--- Added "waypoint" "route" "magnetic difference" "ground speed" "drift angle" "to be flying (flight time)" "yaw" "Doppler radar" "hover" Terms and definitions (see Chapter 3);

--- Modify the composition of the Doppler system (see 4.1,.1991 version 4.1.1);

--- Removed the test effects, indicators, temperature shocks, surface topography characteristics (see.1991 version 4.1.5, 4.1.6, 4.3.3, 4.2.4.1);

--- Increased lighting (see 4.7);

--- Modify the input and output interface (see 4.1,.1991 version 4.1.9);

--- Increasing the measurement speed, navigation and positioning, self-test, hover instructions (see 4.10.1.1, 4.10.1.2, 4.10.1.5, 4.10.1.6);

--- Modify the navigation accuracy of the content (see 4.2.10.2.1,.1991 version 4.2.2);

--- Increased navigation computer content (see 4.10.2.2);

--- Increase the hover indicator and data loading device in some specific indicators (see 4.10.2.4, 4.10.2.5);

--- Modify the vibration test curve in Figure 1 (see 4.11.5,.1991 version 4.3.6);

--- Added Figure 2 random vibration test curve (see 4.11.5);

--- Modify the electromagnetic compatibility (see 4.14,.1991 version 4.4);

1 Scope

GB/T 13186-2017 is the Chinese national standard on general specification for airborne doppler navigation systems, in the field of aircraft and space vehicle engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 29 December 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 July 2018. Classification: ICS 49.090, CCS M50. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the requirements of the airborne Doppler navigation system (hereinafter referred to as Doppler system), test methods, inspection rules, and signs, Packaging, shipping and storage requirements. This standard applies to all types of aircraft used by the Doppler system, Doppler systems used by other aircraft can also refer to the use.
