GPS-A mode is an operating mode supported with the
D-PRS to transmit position data.

D-PRS
D-PRS is a function which simultaneously sends posi-
tion data received from the internal or external GPS re-
ceiver, using the slow speed data packet space, along
with voice in the DV mode.
In the analog format 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 been transmit-
ted or received.
