The GlobalTop Gms-u5LP is a highly sensitive, low power consuming GPS antenna module in a popular SMD 22.4 x 17mm form factor. It utilizes MediaTek GPS MT3329 solution that 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.

Gms-u5LP comes with the addition of a power saving switching mode power supply (SMPS) that can help reduce the overall amount of GPS power consumption by over 30% when compared to the previous generation. Gms-u5LP is using integrated ceramic patch antenna for reception.
