GPS OPERATION
5-13
When D-PRS is selected as GPS TX mode, you can
transmit D-PRS data.
When operating in the D-PRS mode, the following
codes are transmitted to the PC.
D-PRS code is based on APRS
®
code.
(APRS
®
: Automatic Packet Reporting System).

D-PRS
D-PRS is a mode that simultaneously sends position
data received from the internal or external GPS
receiver, using the slow speed data packet space,
along with voice in the DV mode.
In an analog mode, you can transmit or receive
only voice 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.
