Internet APRS Data Utilization for Biosurveillance Applications

APRS is an abbreviation for Automatic Packet Reporting System, and is a method of broadcasting GPS positioning information in real time from packet radio-equipped stations. It was designed in the early 90’s, but it has seen growth in the last few years due to user-friendly software such as WinAPRS or UI-View, and Kenwood’s APRS enabled radio transceivers becoming available. APRS equipped stations send latitude and longitude information, as well as course, speed and altitude of mobile stations. These are commonly set up for use as Search and Rescue operations or special public events such as parades for tactical overviews. Even the International Space Station and a number of low-earth orbiting satellites have an APRS repeater on board, with amateur earth stations watching positions on their PC screens. Many stations also transmit weather data, which is collected for use by the US Weather Service.
