Global Top Technology introduces Gmm-u5LP, the newest
addition in its cost friendly range of GPS modules targeted
towards industrial and telematics applications. Gmm-u5LP is a low
power, high sensitive GPS module which incorporates the
GlobalTop new smart antenna supervisor system, "Antenna
Advisor", that can detects and notifies a user on the various
states of the antenna.
"Antenna Advisor" enables the GPS module to detect and notify
external active antenna connection, open circuit and short circuit
conditions using hardware pin-out and unique software protocol. It
also features antenna short circuit protection to safeguard the
module from being damaged by short circuiting at the external
antenna I/O end. "Antenna Advisor" is very easy to implement and
requires only a single additional resistor.
The Gmm-u5LP also reduces the overall power consumption of a
standard GPS module by over 30% when compared to the previous
generation through a new switching mode power supply. With a
miniscule 24mA when tracking and 30mA during acquisition, Gmm-u5LP
is perfect for mobile devices and telematics applications.
Firmware customization are also available to Gmm-u5LP users
which include geofencing, binary output mode, distance
calculation and many more that help to enhance the overall system
efficiency and shortens development time.
Gmm-u5LP represents the best GPS module GlobalTop and MediaTek
has to offer using the latest MT3329 GPS chipset. With support up
to 66 channels of satellite searching under -165dBm sensitivity,
plus 10Hz maximum update rate for precise GPS signal processing
under low receptive conditions.

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).
