At a dimension of 9 x 12.7mm, GlobalTop Technology's
Gmm-u2p is smaller than its previous generation predecessor.
Gmm-u2p is a high sensitive, incredibly low power consumption (15mA
@ Tracking / 19mA @ Acquisition) GPS module.
It utilizes MediaTek's fourth generation MT3339
single chip GPS technology that supports up to 66 channels of
satellite searching with -165dBm sensitivity and 10Hz maximum
update rate and many of GlobalTop's advanced software customization
services.

The GlobalTop GPS Module Evaluation Kit is the
best way of testing the performance of G.top Mediatek GPS modules.
Not only does it simplify the evaluation process, it also helps
engineers during the design phase.
The evaluation
board can communicate with a computer via a USB cable, and the
module can be controlled through the Mini GPS Tool or PMTK commands
(available through request).
