LOCOSYS S4-0606 GPS module features high sensitivity, low power and ultra small form factor. This GPS module is powered by SiRF Star IV, it can provide you with superior sensitivity and performance even in urban canyon and dense foliage environment. User can add a serial EEPROM (or use the host CPU's memory) to get SiRF CGEE (Client Generated Extended Ephemeris) function that predicts satellite positions for up to 3 days and delivers CGEE-start time of less than 15 seconds under most conditions, without any network assistance. Besides, MicroPower Mode allows GPS module to stay in a hot-start condition nearly continuously while consuming very little power.
