L50 is an ultra slim module with embedded 15.0 × 15.0 × 2.0mm patch antenna. It is built upon the lastest SIRFstarIV ROM version 2.2 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 satellites in the shortest time, even at a very low signal level. Its highly compact design with minimal patch antenna is ideal for portable devices, asset tracking, connected PND, security devices, vehicle management and other industry applications.
L50 supports aided-GPS function without the necessity of downloading data from server since it automatically captures ephemeris data from satellites locally and predicts ephemeris over 3 days without server assistance.
With embedded active jammer remover, L50 can track and remove up to 8 CW (Carrier Wave) type signals up to 80dB-HZ signal level. This feature ensures fast and accurate navigation in hostile signal or high noise environment.
