APRSViewer is an Automated Packet Reporting System (APRS) client application written using the Java programming language. It
isn't 100% complete yet, but it does provide a lot of functionality. It is missing some features that a fully functional APRS
application should provide, such as IGate capability and messaging, but it is a working APRS client application. Development on
this project has taken a temporary back seat to some other projects. If people express enough interest in this project I will
devote more time to APRSViewer.
Some of the features include:
- Sending and receiving APRS packets through a KISS TNC (serial
- Sending and receiving APRS packets over the Internet (APRS-IS)
- SmartBeaconing using the method developed by Tony
Arnerich KD7TA and Steve Bragg KA9MVA
- Mapping APRS reports including proper icons and
decoding of packets
- OpenStreetMap and Virtual Earth map providers
- Viewing APRS messages
- Support for multiple simultaneous TNCs
- GPS integration
- Dead reckoning
- Support for decoding telemetry packets
This application was developed using Java for cross-platform
compatibility. In order to run it you must have Java
installed. This application no longer requires the user to
install any external dependencies.
This is the main screen of the application
This is the station list dialog.
This is the message list dialog
After unpacking the zip file, to run the application, use the command
from the command line. On some systems
just double clicking on the jar file will work as well.
The TNC code has been recently revised to permit multiple
TNCs. Unfortunately this means that for previous users, any
existing TNC will need to be added again to the application as the
settings are now kept in a different format. Beaconing is
tested and working for both APRS-IS and TNCs. I have added
built-in support for additional TNCs, and have provided a dropdown
in the TNC dialog to permit loading the definition for those
TNCs. I have tested the application with Dire Wolf and the
network TNC code is working
