  12. ARRL awarded 2008 International Humanitarian Award to CRSA

  13. The amateur radio in Sichuan province are also awarded

  14. CRSA held the 2009 annual member meeting in Sichuan to commemorate the big disaster

  15. Agenda • Brief Recall of the big disaster • Current situation • Next action

  16. China issued the “Emergency Response Law of the People's Republic of China” in 2007 The Law was issued in 30 Aug 2007 and effective from 1st Nov 2007. Table of Content Chapter 1 General provisions Chapter 2 Prevention and preparation Chapter 3 Monitor and alert Chapter 4 Emergency disposal and rescue Chapter 5 Relief and rebuild Chapter 6 Law responsibilities Chapter 7 Appendix The emergency situation consist of Nature disaster, Accident, Public health disaster, Social security disaster.

  17. Other emergency communication trends International Telecommunication Union Mobile public communication services Professional Emcom network Satellite communication network Future system

  18. ITU Helping the World Communicate ITU-D ITU-T Assisting implementation and operation of telecommunications in developing countries Telecommunication standardization ofnetwork and service aspects ITU-R Radiocommunicationstandardization and global radio spectrum management ITU （International Telecommunication Union） 191 Member States +700 Sector Members

  19. Disaster phases and the radio services involved • Disaster prediction and detection – meteorological and Earth exploration satellite services • Disaster alerting – broadcasting, fixed, mobile and related satellite services • Disaster relief – Amateur, broadcasting, fixed, mobile and related satellite services

  20. Status of studies – needs of future systems Report ITU-R M.2033 “Radiocommunication objectives and requirements for public protection and disaster relief (PPDR)” • Defines objectives and needs for the implementation of future PPDR solutions • Focuses on operational needs around 2010

  21. Resolution 646 (WRC-03) Recommends use of regionally harmonized bands: • Region 1: 380-470 MHz as the frequency range within which the band 380‑385/390‑395 MHz is a preferred core harmonized band for permanent public protection activities within certain countries of Region 1; • Region 2: 746-806 MHz, 806-869 MHz, 4 940-4 990 MHz; • Region 3: 406.1-430 MHz, 440-470 MHz, 806-824/851-869 MHz, 4 940‑4 990 MHz and 5 850-5 925 MHz. • Encourages administrations to facilitate cross-border circulation of radio equipment intended for use in disaster relief situations

  22. Status of studies – Amateur involvement Recommendation ITU-R M.1042-2 “Disaster communications in the amateur and amateur-satellite services” • Encourages the development of robust, flexible and independent amateur service and amateur-satellite service networks, capable of providing communications during disasters and relief operations

  23. Contingency Plan • Contingency base station • Super base station • Group business • News broadcasting • Space-Ground integration Public Mobile communication network emergency communication solution

  24. Space – Ground integration mobile network LEO constellation (Orbcomm……) Satellite emergency communication network

  25. AVCS(Aerial Vehicles Comm Sys) HALO-Proteus（US） New developing / Future Technologies

  26. HAPS(High Altitude Platform Station) New developing / Future Technologies(Cont.)

  27. HAPS Sky Station（US） StratSat（UK） Stratpspheric PL.（JP） Capanina （EU） SkyTower（US） Heliplat（I）

  28. The position of amateur radio emergency communication in disaster relief 1，Part of the disaster relief system; 2，A supplemental of national emergency communication; 3，The prerequisite to function well: Available Non-Governmental communication resources Popularizing communication technology The amateur spirit 4，The most valuable things can provide: In very short time to report disaster situation In very short time provide self relief communication

  29. Agenda • Brief Recall of the big disaster • Current situation • Next action

  30. Action 1 – make amateur radio activity popular This is the basic factor that amateur radio operators can serve for disaster relief. In the Sichuan earthquake there was a hamradio operator (Mr. Tian, BG8FA) in Hanwang town – one of the center area – his equipments was entirely damaged – fortunately, his family were all survived in the big disaster.

  31. Mr. Tian, BG8FA lived in the ground floor of this building, his equipment was entirely damaged by the big earthquake 内容

  32. Action 2 – Setup practice standard for amateur radio emergency operation Enhance CRSA emergency communication exercises. Setup operation standard for emergency communication, Jiangsu province has the first step Corporate with government and social disaster relief forces. International experience sharing. CRSA participated all SET proposed by IARU R1 Actively involve in GAREC meeting Practice on standard emergency communication frequencies

  33. Action 3 – Focus on normal preparation Basic communication skills education Enhance corporation with government disaster relief department Local communication self training Building VHF/UHF emergency networking skills Research amateur radio emergency repeater technology Research amateur radio direction finding rescue technology

  34. Action 4 – Develop technologies and solve problems 200Km stable communication Solve skip problem Stable reporting to command center Digital signal alert Weak signal / Low power communication

  35. 200Km stable communication With “Emergency Response Law of the People's Republic of China”, when disaster occurs, the situation should report to provincial center which normally about 100-200Km far away Develop VHF/UHF repeater system to cover these areas in east developed region. By using HF, need high angle radiation antenna while to consider HF absorb by D and E layer.

  36. Loop antenna and high angle antenna

  37. Relayed by remote station, the 100-200Km station can use HF to communicate Solve skip problem

  38. Solve skip problem (Cont.)

  39. By setup about 5 stations national wide, and link them by VOIP technology such as Echo Link, the command center can easily communicate to the stations in the disaster center. Stable reporting to command center

  40. Sound card XCVR XCVR XCVR PC PC PC Interface XCVR Control Link to internet Station 1 XCVR PC Stable reporting to command center(Cont.) Station X Internet XCVR （Audio） Stations in disaster center Station 3 PC System admin PC Server Listener Station 2 System admin

  41. The digital signal such as RTTY or PSK can transmit characters (including Chinese double byte characters), make the message less distortion. To setup national wide monitoring system under certain protocol, the digital HF/VHF alert system even can be observed from internet! Digital signal alert

  42. Digital signal alert(Cont.) The Warbler 80m PSK transceiver. BA5AG has modified the schematic diagram to easily fit in China.

  43. Digital signal alert(Cont.) The KN-Q8 made by BA6BF. It is a very small yet full function rig for 40-20m, convenient for field use.

  44. Digital signal alert(Cont.) By using pocketDigi, integrate with KN-Q8, it’s easy to transmit Chinese Characters by using PSK31.

  45. Given the power limit and antenna status, low power stations should be took into consideration. Weak signal processing is of vital importance in disaster communication. JT65/FSK144/QRSS technology are worth to apply in this area. Weak signal / Low power communication

  46. Weak signal / Low power communication(Cont.)
