  1. NEKSUN KØHAM.com SUNFLOWER INTERLINK NE KS ARC APRS Emergencies & Drills Kansas City • kcAPRS.org • Coordinating organization • for APRS in KS, KC & MO • NEKSUN • Join in the fun of APRS and repeater building across Northeast Kansas kØham.com kcAPRS.org APRS Organization

  2. Why We Are Here • What is APRS? • What software should I use? • What Hardware should I use? • What do I need to know about the existing APRS network? • How can I use APRS for Emergencies? • How can I use APRS for Drills?

  3. What is APRS • Automatic Position Reporting System (previoulsy Automatic Packet Reporting System) • Packet communication protocol for sharing live data on a network in real time • Real time tactical communications and display system for emergencies and public service applications (APRS Spec)

  4. How is APRS different from Packet Radio? • Communication is ‘one to many’ • Uses generic digipeating with standard aliases • Supports intelligent digipeating to reduce network flooding • Uses UI frames for messaging, bulletins and announcements • Provides maps and other features

  5. Frequencies • VHF • Primary (Digis): 144.39 1200 baud • Secondary: 144.39 1200 baud • UHF • Primary (Digis): 446.175 1200 baud • Secondary: 441.175 1200 baud • HF • 30M 10.15151 LSB 300 baud

  6. Emergency Operations • What do you need 2B a good Emergency Operator? • INCLUDING SAR • Detailed Map • May be deployed to unfamiliar territory. • Latest WX info from the NWS • Need to see Watches & Warnings • Radar • Field Observations • Need to see temperature & wind all around • See other spotters • Need to know where all field units are deployed • Objects • Indicate damage or roadblocks on a map for all to see • List of Shelter Locations • Short Messaging • Communicate more confidential info to EOC or field units • Email capability • Need to be able to send short messages to internet users

  7. APRS Data Types • Station Beacons • Contain call, location, symbol, status, time, speed, alt. vector • Wx beacons add wx info • Objects • Created by an APRS as an icon • Contains same data as beacon • Can be moved and adopted by other APRS stations • Messages • Short Text (<68 char) between two stations in 4 ways • Station to Station direct or via digi • Station to Station via TCPIP • RF station to Internet Station • RF station to email recipient

  8. APRS Emergency Operations • On Demand Station Types • Internet Client • Internet Website • Base • Mobile • Tracker • Existing Infrastructure • Igate • Digi

  9. Internet Client • Using a software client like UI-View • Can see all APRS station & beacon info • Can send beacons & msgs if setup with a local IGATE + Avoids having another radio in the EOC Avoids interference with other VHF radios Good Mapping & weather integration - Requires good internet connectivity

  10. Internet Website • Using a webpage like findu.com or aprsworld.net • Can see all APRS station & beacon info • Can send beacons & msgs if setup with a local IGATE + Avoids having another radio in the EOC Avoids interference with other VHF radios Good Mapping & weather integration No APRS software installation required - Requires good internet connectivity No abililty to send objects, beacons, or messages

  11. Base • Uses a TNC & Radio & PC to Send & Receive & display data • Software Client (like UI-View) displays info seen on a Map • May also connect to internet to see more stations nationwide or act as an IGATE • Can act as a fill in digi (set tnc myalias to wide1-1)

  12. Mobile Uses a TNC & Radio & PC to Send & Receive & display data • Software Client (like UI-View) displays info seen on a Map • May also connect to internet (via wi-fi) to see more stations nationwide or act as an IGATE • Can act as a fill in digi (set tnc myalias to wide1-1)

  13. Tracker • Uses Transmit TNC and Radio • Only sends position for that particular TNC & Radio • Cannot see other APRS users • May be used on Canteens or other unmanned resources

  14. Infrastructure • IGATES • Can be home users or dedicated stations • Use Radio, TNC and Internet connection • Sends all RF data to Internet Servers • Sends SELECT Internet Data to RF (Bandwidth Constrained) • DIGIS • Located at high locations throughout the area • Respond to Wide1-1, Wide2-2, Wide3-3 • Respond to their own call for specific routing

  15. Mobile Path • Metro Example: • APRS V WIDE1-1,WIDE2-1 (2 hops) or • Non-Metro Example: • APRS V WIDE1-1, WIDE2-2 (3 hops) Home (Fixed) Path • Metro Example: • APRS V WIDE2-2 • Non-Metro Example: • APRS V WIDE3-3 or • APRS VIA K0XYZ, WIDE2-2

  16. UI-View 32 Solution Detailed Map: Show world Map Zoom full in Show Search capability Address, County, State, Phone, Mile Marker, Call Show Overlays (Spotter Locations) Show Underlays (Aerial Photos) Show UI-Terra

  17. UI-View 32 Solution Latest WX info & Observations: Show UI-NWS Show active colored counties Click for details Show finger wx_srv Show Field Wx Station observations

  18. UI-View 32 Solution Messaging: Show sending a message direct Show sending a message via digi Show sending a message via internet Show sending an email message

  19. UI-View 32 Solution Tracking & Zooming: Show Auto Track (Cross Hairs and Track zoom) Show UI-Height Track With Height based color Show movement alarm Show UI-History Show FindU Log Converter Show FCC server

  20. UI-View 32 Solution Objects: Show moving object Show UI-Signpost Show inactive object Difference between objects & overlays Show Objects list

  21. Hardware Getting on the Air with APRS – What to Buy/Scrounge • Base station requirements • 2 meter radio and antenna • Desktop computer • TNC or soundcard/interface • Mobile station requirements • 2 meter radio and antenna • Variables

  22. Mobile/Portable Variables • Mobile-Track & View • GPS • Laptop • TNC • Mobile-Tracking Only • GPS • Tiny Track, or Tracking TNC • Portable-Tracking Only • GPS • Tracker interface device • Power source for portability

  23. Hardware • Computers for UI-View • Pentium II, 128mb 3gb avail, minimum • Faster PC=Faster Map refresh • Consideration for a TNC with GPS • 2 serial ports are needed (Unless KPC3+) • If only 1 serial port is available, can use a “Port sharing” device • Any TNC will do with fixed location and a PC attached.
