GPS module GY neo-6m uses the popular Ublox Neo 6M GPS chip.
The detachable high gain antenna supports fast satellite acquisition, keeping the gps accuracy within 5m. There's dedicated EEPROM and a backup battery onboard that stores the satellite ephemeris data when powered off and thus helps faster location estimation as soon as the module powers on.
