Compliance overview
Scope and applicability
This standard is mandatory and applies to all aeronautical radio navigation stations, including Non-Directional Beacons (NDB), VHF Direction Finders, Instrument Landing System (ILS) components (Localizer, Glide Path, Marker Beacons), Microwave Landing System (MLS) components (Azimuth and Elevation stations), VOR, DME, TACAN, and Precision Approach Radar (PAR) stations. It is essential for equipment manufacturers and airport facility planners. It does not apply to general communication stations.
Technical requirements
The standard specifies the electromagnetic environment requirements for various aeronautical radio navigation stations. It defines the minimum protection ratios against interference from industrial, scientific, and medical (ISM) equipment, as well as other active interference sources. For instance, it sets specific protection ratios for NDBs, VORs, and ILS localizers. It establishes strict site protection zones for each type of station. These zones define the maximum allowable heights for obstacles such as buildings, trees, and terrain, and specify minimum distances from high-voltage power lines, railways, and highways. Engineers must ensure no unauthorized obstacles or ground traffic exist within these critical zones. The standard also details the required minimum signal field strength within the coverage area for each station type, operating across various frequency bands from 150 kHz to 9 GHz. Appendix A provides calculation methods for protection distances against ISM equipment interference.
Testing methods
Measurement of signal and interference field strength must be conducted using instruments compliant with GB/T 6113.101, utilizing the Root Mean Square (RMS) detector method. Laboratory tests must meet GB/T 6113.104 requirements, while on-site testing must follow YD/T 1633.
FAQs
What products or facilities are regulated under GB 6364-2013?
It regulates the electromagnetic environment for all aeronautical radio navigation stations, including NDB, VOR, DME, ILS, MLS, and TACAN systems.
Is GB 6364-2013 a mandatory standard?
Yes, all technical content in this standard is mandatory for relevant facilities and equipment operating in China.
What are the key updates from the previous GB 6364-1986 version?
The 2013 version separates general technical requirements from specific station requirements, adds provisions for MLS (Azimuth and Elevation stations) and decimeter-wave navigation stations, and updates the interference measurement method to RMS detection.
