YAAC can be used as a stand-alone APRS client, an APRS RF-Internet gateway (I-Gate), or as a AX.25 digipeater. It supports 16 different data reporting views as delivered, and can be extended with user-written "plugins" to add more functionality. YAAC's map rendering does not depend on Internet connectivity, so it can be used wherever a portable computer and radio/TNC can be located.
