D-PRS & APRS
Share D-STAR GPS position onto the APRS network.
APRS is a neat technology for sharing info on your QTH, or sharing your position while mobile. Some use it when traveling off the grid to leave a trace of the route they ended up taking in the event of an emergency. Still others use APRS to commune with nearby hams.
D-STAR transmissions contain location information where available (if the radio GPS is active and the feature is turned on), so similar functionality is automatic among D-STAR users. In the spirit of cross-compatibility though, the D-PRS feature was added; allowing the D-STAR location information to be shared on the APRS network.
To enable this, all one needs to do is use the Gateway function to communicate with a D-PRS capable repeater (your call sign must be gateway-registered).
Use a local D-PRS capable gateway repeater with GPS enabled on your radio. For Columbus-area gateway notes, see W8CMH.
You can check your status on sites such as APRS.fi by searching for your call sign. Software such as D-RATS can also exchange GPS position reports over D-STAR.
