摘要

If you've been reading The World of VHF over the last few months, you'll recall that we have mentioned Automatic Packet Reporting System (APRS) on a few occasions. Wikipedia says of APRS, Automatic Packet Reporting System (APRS) is an amateur radio-based system for real time tactical digital communications of information of immediate value in the local area. In addition, all such data is ingested into the APRS Internet system (APRS-IS) and distributed globally for ubiquitous and immediate access. Along with messages, alerts, announcements and bulletins, the most visible aspect of APRS is its map display.
