The Amicus GPS shield contains a multi channel GPS receiver, as well as a 16k byte (128 kbit) serial (I2C) eeprom, and a 3 Volt, 12mm battery socket in order to maintain the receiver's built-in RTC (Real Time Clock).
An SMA socket allows attachment of the GPS receiver's aerial.
More detail is available on the Amicus website
