GPS Setup

IPSC3 can receive GPS position information from supported DMR radios and forward valid positions into the network GPS map and APRS-IS gateway. The normal IPSC3 data service radio ID is 9998.

AnyTone GPS / APRS

• Make sure the radio DMR ID is correct. IPSC3 uses that ID to look up the APRS callsign from RadioID.
• Enable the GPS receiver and confirm the radio has a valid GPS lock before testing.
• Create a digital contact named IPSC3 GPS as a private call to 9998.
• In Digital APRS, enable reporting to the IPSC3 GPS contact on Timeslot 1.
• Use an IPSC3 repeater or hotspot channel as the GPS/APRS report channel.
• Leave Analog APRS off unless you specifically want separate RF APRS operation.
• Do not beacon more often than every 10 minutes. Beaconing more often than every 10 minutes will result in your transmissions being blocked from the network for 1 hour.
