D D-PRS
D-STAR Packet Reporting System (D-PRS) is
a mode that simultaneously sends position data
received from an external GPS receiver, using the
slow speed data packet space, along with voice
audio in the DV mode. In the Analog mode, you can
transmit or receive only voice audio or data at one
time. However a D-PRS capable radio can transmit
or receive message data or GPS position data at the
same time voice is being transmitted or received.
I-GATE is required to send position data to the APRS
server.
