L20
GPS module
The L20 module provides the high performance GPS engine module which is embedded the SiRFstarIV™ chip solution with SIRFaware™ technology. With 48 PRN channels, L20 acquires and tracks satellites in the shortest time even at indoor signal level. With a compact profile of 16.0mm × 12.2mm × 2.4mm, it perfectly suits for vehicle tracking, personal tracking, asset tracking, connected PND, security device and other industrial applications.
L20 supports aided-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.
