XASTIR - An Opensource APRS application

Automatic Packet Reporting System (APRS™) (also known as "Automatic Position Reporting System") is an amateur radio based digital communication system for real-time exchange of digital information to users on the network. APRS was originally developed by Bob Bruninga, WB4APR more than 20 years ago. It has since evolved into a robust system of interconnected networks. Xastir is a computer application that provides client access to this network using the APRS protocol.


Xastir is an open source software project maintained by Developers and Contributors from all over the globe and is provided free under the GNU General Public License. From its early beginnings, Xastir has evolved into a very robust client with a rich feature set that rivals any other APRS client.

 Xastir APRS Client is a FREE! software program that will run on several different operating systems, including Linux and Windows. Amateur Radio operators trained in the use of Xastir run the program which is attached to two-way amateur radio and TNC (radio modem). The Xastir software program is backed by active developer and user communities.
