Aprstracker is an open source firmware for PIC based trackers like the 
TinyTrak, KF161-Tracker, or KF163-Tracker.

he following new features have been added in aprstracker v0.11.

    * Added support for RMC. Aprstracker can now operate, incl.
      SmartBeaconing, when RMC is the only available NMEA sentence. GGA
      is only needed if transmission of altitude information is enabled.
      As with previous versions, aprstracker can also operate with just
      GGA sentences without SmartBeaconing. Or with GGA and VTG
      sentences with SmartBeaconing.
    * The GPS LED now doubles as a "GPS alive" and a "GPS lock"
      indicator. If the GPS is not locked yet, then the LED is mostly
      off, and will flash on every time $GPRMC or $GPGGA is received. If
      the GPS is locked, then the LED is mostly on, and will flash off
      every time $GPRMC or $GPGGA is received.
    * An output signal is available to control a PLL synthesizer of a
      transceiver. This enables the usage of a transceiver for both
      voice and APRS communications.
    * Status type APRS frames can now have a user configurable text.
      This feature is not available in the build for the pic16f628
      because this microcontroller does not have enough EEPROM storage.

The following is not really a new feature, but should be mentioned 
anyway. The modem tone generation interrupt service routine and the 
EEPROM read routines have been further optimized in v0.11.
