DCF-GPS offers DCF sensor drivers for various GPS sensors. The current DCF-GPS version offers sensor driver for Ublox Antaris 4 GPS sensor that reports latitude and longitude of the sensor. The driver supports serial port communication and emulated serial port communication via USB.

The ublox Antaris 4 LEA-T receiver (although all Antaris 4 receivers should work) is a small, light weight, low power GPS receiver with 2.5 meter CEP accuracy. The ublox receiver supports all standard NMEA messages which provide processed GPS Data, as well as the UBX messages which support all raw data. However, DCF only supports the standard NMEA messages. Position is available at a rate of 4Hz.
