What is D-PRS?
D-PRS (D-Star Position Reporting System) is APRS for D-STAR. As we know, D-Star radios in DV mode are capable of sending voice while also providing a data stream which can include GPS information. D-PRS converts ICOM D-STAR radio GPS information into APRS. Most D-STAR repeaters now have D-PRS implemented on the gateway, and can send these D-PRS packets to the APRS Internet Server network. APRS maps show real-time APRS information and can track D-STAR stations on the Internet. Newer D-Star radios have integrated GPS capabilities, and others can have a GPS unit plugged into them.
