中国民用航空局 空中交通管理局 Air Traffic Management Bureau. CAAC Civil Aviation Air traffic control Technology Equipment Dev. Co. Ltd 民航空管技术装备发展有限公司 A Briefing of ADS-B(OUT) Applications/Projects in China
Policy of ADS-B in CHINA � September 2008, CAAC released Advisory Circular IB-FS -2008 -002 “Automatic dependent surveillance-broadcast (ADS-B) in the flight operations ” � May 2010, CAAC released Advisory Circular AC-91 -FS/AA -2010 -14 “ 1090 ES Automatic dependent surveillancebroadcast airworthiness and operational approval guide in the absence of radar ” � November 2011 , CAAC released Advisory Circular AC-93 TM-2011 -01 “ATC operating procedures of Automatic dependent surveillance-broadcast(ADS-B)” � “Technical Standards for 1090 MHz Extended Squitter Automatic Dependent Surveillance – Broadcast (ADS-B) Receiver”
ADS-B Ground Stations Equipment � In September 2009, ADSB ground station made by TEDC was used in Chengdu , and completed a comparison test with Sensis' ADS-B ground station. � The test results shown that the main technical indicators of the TEDC ADSB ground equipment and Sensis ADS-B receiver is quite similar. The performance of TEDC ADS-B ground receiver provides better sensitivity. �
ADS-B Ground Station Equipment � In February 2012, CAAC issued license for the ADS-B 2000 A ground station (made by TEDC). It's the first license of ADS-B ground station equipment issued for national vender in China. � CAAC issued a license, indicating that the ADS-B 2000 A technology has matured and is ready for deployment
Breifing of ADS-B Applications Cheng Du-Jiu Zhaigou ADS-B validation project Cheng Du- Lhasa Air Route ADS-B surveillance project H 15 Air Route(Domestic ATS Route) ADS-B surveillance trial project Li Jiang Airport ADS-B trial project Chao Yang Airport General Aviation ADS-B surveillance trial project
Cheng Du-Jiu Zhaigou project Chengdu Jiuzhaigou ADS-B project is the first ADS-B project in China which completed the installation on 08 MAR 2008. It is mainly used for the experiment and evaluation of the ADS-B technology. � � The Receiver is provide by Sensis. The evaluation mainly contains : ◦ ◦ ◦ Accuracy evaluation Speed info evaluation Heading info evaluation Pseudo target rate evaluation Position report evaluation Data link evaluation
Cheng. Du-Jiu Zhaigou project Chengdu - Jiuzhaigou project to compare the ADS-B and radar data, concluded that: ◦ Accuracy, integrity, pseudo-target rate, reliability, continuity of the position report, dispersion, error characteristics, the ADS-B data is better than the Radar data; ◦ The accuracy of speed/heading, track continuity, ADS-B is better than Radar. ◦ The Flight Level/Coverage , ADS-B and Radar is quite similar; Overall, ADS-B performance is better than Radar and ADS-B data link can meet the demand of the growing China Air Traffic Management 。
Chengdu - Lhasa project � � Chengdu -Lhasa project ◦ CAAC approved the project in June 2009; ◦ January 2010,Completed the contract negotiations (Receiver is Thales products); ◦ August 2010 , Completed the equipment installation ; ◦ July 2011, Chengdu - Lhasa route began to implement ADSB surveillance conditions narrow interval; Chengdu - Lhasa air route have achieved ADS-B continuous coverage
Chengdu - Lhasa project The coverage of Chengdu - Lhasa project
Chengdu - Lhasa project As of February 2012, Chengdu- Lhasa project has played an important role. ◦ Narrowing of the route clearance interval (from 10 minutes to adjust to 7 minutes) ◦ Gradually increase the flow of the airspace ◦ Increase route capacity and flight punctuality The future, ADS-B technology, on the route, the flight interval will be shortened to 5 minutes, the implementation time will also be allweather operation, will also use the RVSM level standards –from 600 m vertical separation adjusted to 300 m.
Li. Jiang Airport trial project In order to keep Lijiang Airport normal operation during the ILS maintenance period, the CAAC Southwest Regional Administration and the Yunnan Airport Group launched the Lijiang airport ADS-B trial project. The Ground Receiver installed at Moyanshan VHF station at elevation of 2800 meter。 The project used ADSB-2000 A ground receiver,the technology parameter as follows: Sensitivity: (detectable) sensitivity -93 dbm, 99% detection rate sensitivity -87. 9 d. Bm. Antenna: glass fiber reinforced plastics, omni antenna 1. 8 meter Channels: 2 channels, working in parallel.
Li. Jiang Airport trial project Lijiang Airport 24 hours of the ADS-B data in real time coverage area map (red line for the ADS-B tracks) � � In complex terrain (located on the southern edge ofthe Tibetan Plateau, t he mountains from 2000 m to 5000 m canyon Transitional Zone) as far as observation distance of more than 300 Km(track appear dis continuous phenomenon is d ue to surrounding terrain)
Li. Jiang Airport trial project 70000 � February 24, 2011, Lijiang Airport trial project has completed the installation. 60000 50000 40000 30000 In 6 months of continuous 20000 observation, most of the time of the Lijiang region 10000 ,the GPS PDOP value is less than 3. 0 GPS theoretical positioning accuracy is less than 15 meters. But The picture above shows the location of, and there are still some time, PDOP of value NUCp value of Lijiang experiment collected 112 aircraft, including five aircraft continued to send is bigger than 4, the aircraft NUCp = 0 position accuracy value, which indicates value less than in 5 that about real airspace, 4. 5% with the ability of ADS-B aircraft not properly configured its extend squitter
H 15 air route project � The Northwest Air Traffic Management Bureau start H 15 air route ADS-B trial project, to test H 15 route aircraft ADS-B surveillance. H 15 route is a domestic ATS route that link Tibet and Lanzhou, it's no radar area. 名称 坐标 距上点的距离 Lanzhou N 36 -30 -48 #N/A E 103 -37 -24 Xining N 36 -31 -42 142. 7 Km E 102 -01 -54 � 6 ADS-B stations ( Lanzhou, Xining, Golmud, Delingha, Chaka, Budongquan) Chaka N 36 -47 -27 265. 8 Km E 99 -04 -45 � � The total length of the coverage area of more than 990 Km, the highest station 4200 m abovesea level.

H 15 air route project Surveillance maps at the H 15 route the ADS-B track real-time
H 15 air route project In order to solve the problem of ground station data processing, the Northwest Air Traffic Control Bureau require to establish ADSB data processing center in Lanzhou. ◦ Extend the function of the ADS-B ground stations, and improve the ADSB security. ◦ By the ADS-B ground stations precision time tag, substantial increase in the ADS-B data security issues. ◦ The data interface used IP protocol. The output data is shared through two data links - an E 1 link transmission to Xi'an ATC House, another linked to the Lanzhou display subsystem.
H 15 air route project H 15 route trial project results: ◦ Verify the reliability of domestic equipment in the high altitude, in complex terrain areas. ◦ Verify the functionality and efficiency of the domestic ADS-B data processing center 。 ◦ The remote sites are built in the Chinese mobile communication base stations, test the feasibility ofthe use of mobile base stations, and data linkavailability and reliability. ◦ ADS-B airborne equipment installation rate /availability / accuracy of basic data collection in China's western region.
