APRS: 1998 Dayton Hamvention Activity

The javAPRS map below shows the APRS activity in and around the Dayton area during the 1998 Hamvention. You may zoom this map, or pop up more detailed maps as shown.

(Be patient...the applet, map and data files are over 300k, so depending on your connection speed it may take a couple of minutes to load.)

The APRServe network was developed by Steve Dimse to tie together all of the APRS VHF networks in the world so that mobile APRS stations can have nationwide, if not worldwide, communications coverage. Any APRS home station that is logged into www.aprs.net can serve as an automatic Internet Gateway to everyone within his local area. In this way, the APRServe internet system is transparent to all users. The system includes automatic messaging between amateurs on the internet and rf networks.

APRS is a system developed by Bob Bruninga, WB4APR, which uses amateur radio to transmit position reports, weather reports, and messages between users. My contribution is the internet portion of the system. Although ham radio is capable of digital long distance communications, it tends to be slow and unreliable, especially when compared to the internet. I've written software to take the data received locally and make it available via the internet, to be displayed with a Java applet.

At times you may see vehicles, planes, or boats moving around town. These vehicles obtain their location using the satellite system known as GPS, and transmit that position for others to follow. There are also a few weather stations visible on the map. Click on one of these to see their current weather conditions.

For more information about APRS see WB4APR's pages or the APRS Vitual Meeting.
