APRS is a registered trademark of APRS Software and Bob Bruninga, WB4APR.
Since 1997, the APRS Internet System has been collecting APRS data from around the world. The purpose behind this system was to link all the various local RF networks into a single real-time wide area network. The system has been successful beyond my wildest dreams, with hundreds of simultaneous users and thousands of stations reporting, the system handles about one million packets a day. While the original design for this system stored a single position and weather report for each station, there was no provision for any longer-term storage of the data.
The findU system adresses this shortcoming. Each incoming packet is parsed by a Perl script and stored in a MySQL database, currently occupying over 77 GB. Perl CGI's are used to access the database and dynamically generate web pages.
This web site uses a loaded Dell PowerEdge 2650 Dual Xeon computer hosted at a colocation site in New Jersey, with a similar live backup server hosted in Texas.
