  1. Automatic Position ReportingSystem (APRS)An Introduction to APRS via Amateur Radio BCYLARA Conference Kelowna, BC - May 2006 “In The Sunny Okanagan !” “Okanagan Lake - Home of the Ogopogo!”

  2. Norm Barton – VE7BZCCommunications Coordinator Central Okanagan Reg. Dist. Emergency Operations Centre Fire Station #1, Kelowna, BC www.cordeoc.ca Locally, we acknowledge the efforts of Ian McLaughlin – VE7BST who has been a pioneer for OCARC sponsored APRS networking and I-gating in the Okanagan.

  3. APRSDeveloper andProgram Authors…

  4. APRSDos the original APRS program… • Developed by: Bob Bruninga, WB4APR for the PC when he wanted a cost effective mapping program that would allow positioning of mobile stations using GPS receivers. (Later developed as Windows-based “WinAPRS”) by Sproule Bros.

  5. “UI-view” was developed byRoger Barker G4IDE (SK-2004) …who willed his UI-view program, and Winpack – a packet radio program,(free) to the Amateur Radio World.(Roger asked users to make a donation to their local Cancer Society)

  6. UI-view32 is currently the most popular Amateur Radio APRS program…Its best features:Superior mappingOpen Source Code – means lots of “add-ons”Free! Second most popular – WinAPRS - Cost $65 (approx.) closed code – no add-ons, mapping is difficult.

  7. Some examples of Free “add-on programs” for UI-view…“FindU” log converterMovement alarmLog call sign extractorWeather watcher Local area APRS RF and traffic analyzersWeb serverMessage printeretc., etc., etc.!

  8. APRS needs the GPS (Global Positioning System)to work!…

  9. How you “know” where you are using “GPS” Approx. 22,000 Km altitude 24 Satellites + 5 Ground Stations Maintained by USA DOD A fourth satellite reading resolves these time differences GPS Receiver Trilateration !

  10. What is APRS? • It is a method of transmitting GPS and “Ham” Operator information via Amateur Radiothat includes: • Location and tracking ofvehicles, emergency sites, search personnel, community events, etc. Note: all examples are UI-view32 screen captures

  11. APRS information can be displayed, in real time, on a computer Map.

  12. UI-view Central Okanagan Map

  13. UI-view32 and local mapping - see the positions of cars ve7bzc-3, va7kb and the location of the CORD EOC – ve7eok

  14. Examples of information that can be transmitted: Information that can be extremely useful during emergencies ! Location coordinates, course direction, altitude,speed, temperature and voltage.

  15. The arrows: Coordinates, Compass Bearing from the receiving station, Speed, Height, Voltage and Temperature.(UI-view coordinates are in Deg., Min., decimal Min.)

  16. APRS information transmitted via Amateur Radio can also include: Ham Radio Weather Station Information

  17. Weather data transmitted by ve7mmg-1 Place the cursor on, or “right click” on icon.

  18. Two ways to “get on” APRS… • Mobile or Portable via RF (moving location) • Home via Computer and/or RF (fixed location)

  19. APRS Mobile / Portable components:GPS + radio with a “built-in” TNC such as the Kenwood D700 mobile or D7AG handheld… (TXandRX on 144.390MHz) Or a GPS Receiver + TNC “black-box” (such as TT3 & Open Tracker) + a VHF radio

  20. A Typical Portable/Mobile SetupGPS + Radio + TNC

  21. Home APRS components:A Computer with Internet connectionand an APRS Program You can add RF with a radio + TNC…

  22. All these “RF beacons” floating around in the atmosphere are part of the Worldwide APRS Network: How do we access it ?

  23. Putting APRSusers on theInternet Steve Dimse, K4HG, of Miami Floridawrote an APRS display program called “JavAPRS”.This program and its companion program, APRServe, work with the Internet to allow viewers to see real time datalocally and from other parts of the World. Check Steve’s web site at: www.findu.com

  24. APRS Network components:Radio beacons, Computer beacons, and the Internet. Accessing the data…

  25. Examples of Amateur Radio APRS at work in local Okanagan Emergency Operations...

  26. Amateur Radio + GPS + APRS and Emergency work… + +
