LS2022A is a complete stand-alone GPS smart antenna module, including embedded patch antenna and GPS receiver circuits. The module is powered by SiRF Star IV, it can provide you with superior sensitivity and performance even in urban canyon and dense foliage environment. With SiRF CGEE (Client Generated Extended Ephemeris) technology, it reliably predicts satellite positions for 3 days that are stored in the on-board EEPROM and delivers CGEE-start time of less than 15 seconds under most conditions, without any network assistance.
