L50

Slim GPS module with integrated Patch Antenna

L50 is an ultra slim module with embedded 15.0×15.0×2.0(mm) patch antenna. It is built upon the SiRFstarIV™ chip solution which offers high performance GPS engine. Alongside highest reliability and quality of patch antenna, L50 also offers 48 PRN channels, which allows the module to acquire and track satel-lites in the shortest time, even at a very low signal levels. L50 is also compatible with 18.0×18.0×2.0(mm) patch antenna. Its highly compact design with minimal patch antenna perfectly suits vehi-cle management, asset tracking, personal tracking, connected PND, security devices and other industry application.

L50 supports A-GPS function without the necessity of data download from server since it captures ephemeris data from satellites locally and predicts ephemeris out to 3 days.
