Gms-u1LP is an all-in-one, high sensitivity, lower power consumption, small SMD form factor GPS module featuring incredibly low power consumption ( 24mA @ Tracking / 30mA @ Acquisition) using the latest MT3329 GPS engine with switching mode power supply which saves power by up to 30% compared to previous generation of PA6 family. In addition to SMPS, Gms-u1LP also supports up to 66 channels of satellite searching with -165dBm sensitivity and 10Hz maximum update rate for precise GPS signal processing under low receptive, high velocity conditions. Value-added software customizations such as binary mode and 1-sentence mode that can further enhance the overall system efficiency are also available upon request!
