2.  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 “1090ES Automatic dependent surveillance-broadcast 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”

3.  In September 2009, ADS- B 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 ADS-B ground equipment and Sensis ADS-B receiver is quite similar.  The performance of TEDC ADS-B ground receiver provides better sensitivity.

4.  In February 2012, CAAC issued license for the ADS-B 2000A 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 2000A technology has matured and is ready for deployment

5.  Cheng Du-Jiu Zhaigou ADS-B validation project  Cheng Du- Lhasa Air Route ADS-B surveillance project  H15 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

6. Chengdu Jiuzhaigou ADS-B project is the first ADS-B project in China which completed the installation on 08MAR2008. 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

7.  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 。

8.  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 ADS- B surveillance conditions narrow interval;  Chengdu - Lhasa air route have achieved ADS-B continuous coverage

9. The coverage of Chengdu - Lhasa project

10.  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 all- weather operation, will also use the RVSM level standards – from 600m vertical separation adjusted to 300 m.

11. 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 the Lijiang airport ADS-B trial project. The Ground Receiver installed at Moyanshan VHF station at elevation of 2800 meter 。 The project used ADSB-2000A ground receiver ， the technology parameter as follows ： Sensitivity: (detectable) sensitivity -93dbm, 99% detection rate sensitivity -87.9dBm. Antenna: glass fiber reinforced plastics, omni antenna 1.8 meter Channels: 2 channels, working in parallel.

12.  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 300Km(track appear dis continuous phenomenon is d ue to surrounding terrain )

13.  February 24, 2011, Lijiang Airport trial project has completed the installation.  In 6 months of continuous observation, most of the time of the Lijiang region ， the GPS PDOP value is less than 3. GPS theoretical positioning accuracy is less than 15 meters. But there are still some time, PDOP of value is bigger than 4, the aircraft NUCp value less than in 5 The picture above shows the location of, and NUCp value of Lijiang experiment collected 112 aircraft, including five aircraft continued to send NUCp = 0 position accuracy value, which indicates that about real airspace, 4.5% with the ability of ADS-B aircraft not properly configured its extend squitter

14.  The Northwest Air Traffic Management Bureau start H15 air route ADS-B trial project, to test H15 route aircraft ADS-B surveillance.H15 route is a domestic ATS route that link Tibet and Lanzhou,it's no radar area.  6 ADS-B stations ( Lanzhou, Xining, Golmud, Delingha, Chaka, Budongquan)  The total length of the coverage area of more than 990Km, the highest station 4200 m abovesea level.  The project use ADSB-2000A Receiver 名称坐标距上点的距离 LanzhouN 36-30-48 E 103-37-24 #N/A XiningN 36-31-42 E 102-01-54 142.7Km ChakaN 36-47-27 E 99-04-45 265.8Km DelinghaN 37-21-00 E 97-15-00 174.3Km GolmudN 36-23-36 E 93-54-36 316.4Km BudongquanN 35-32-36 E 93-54-36 94.4Km

17. In order to solve the problem of ground station data processing, the Northwest Air Traffic Control Bureau require to establish ADS- B data processing center in Lanzhou. ◦ Extend the function of the ADS-B ground stations,and improve the ADS- B 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 E1 link transmission to Xi'an ATC House, another linked to the Lanzhou display subsystem.

18.  H15 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.

19. The CAAC Northeast Regional Administration launched ChaoYang Airport General Aviation ADS-B surveillance trial project in Oct 2011. The Ground Station installed in the Phoenix Mountains,Chaoyang. the project using ADSB- 2000A receiver.
