APRS Tracker Digi iGate

Stay visible. Stay connected.

This app is a tool for radio amateurs, civil defense volunteer teams, and operators using the APRS protocol in field activities.

The app allows you to transmit your position to the APRS-IS network via the internet and also operate directly via radio using AX.25 packets with 1200 AFSK modulation. It can be used for individual tracking, local communication, and supporting the infrastructure of an APRS network.

Whether in expeditions, amateur radio events, travel in remote areas, or search and humanitarian aid operations, APRS Tracker provides features to track stations, share points of interest, and expand APRS coverage.

KEY FEATURES
APRS-IS Tracking
Send your GPS coordinates to APRS-IS servers via the device's internet connection. Positions can be tracked on compatible public services, such as aprs.fi.

AX.25 / 1200 AFSK RF Mode
Transmit and receive APRS packets through the device's audio input and output. With a radio and a compatible audio interface, you can operate via RF even without internet access.

APRS Digipeater
Use the app as a digital repeater to extend the range of stations in the area. The Digipeater processes paths compatible with New-N rules and includes controls against loops, invalid paths, and duplicate packets.

iGate Mode
Forward valid packets received via radio to APRS-IS, allowing local stations to be viewed on the worldwide APRS network. Optional internet-to-RF forwarding features packet type selection, radius definition, security filters, and frequency limits.

APRS Objects
Register important points, such as shelters, support bases, aid posts, repeaters, obstacles, risk areas, or meeting places. Each object can contain a name, coordinates, symbol, and message, with publication via internet and/or RF.

Mobile or Fixed Station
Use dynamic location while on the move or configure fixed coordinates to operate as a base, iGate, Digipeater, or support station.

Symbols and Status Messages
Choose the APRS symbol representing your station, vehicle, or activity, and add a message to inform your condition or mission.

Communication Monitoring
Track sent and received packets in the integrated terminal, along with the status of the APRS-IS connection and RF operation.

Automatic Reconnection
After temporary internet interruptions, the app attempts to re-establish the connection with the APRS-IS server.

USE CASES
Tracking during trips, expeditions, and outdoor activities.

Monitoring of vehicles and volunteer teams in the field.

Support for search, rescue, civil defense, and humanitarian aid operations.

Local APRS radio operation in areas without internet.

Temporary installation of an iGate or Digipeater to expand coverage.

Publishing shelters, bases, risks, and support points as APRS Objects.

Technical monitoring of AX.25 packets and APRS-IS communication.

SIMPLE AND CONFIGURABLE
Enter your amateur radio callsign, Passcode, server, and transmission preferences to begin. RF, Digipeater, and iGate features are disabled by default and only work when enabled by the user.

IMPORTANT REQUIREMENTS
Access to APRS-IS requires an amateur radio callsign and a valid Passcode.

RF operation requires a radio and a compatible audio interface. Performance depends on equipment, audio levels, VOX/PTT configuration, and channel conditions.

Continuous use of GPS, audio, and background execution may increase battery consumption.
