The FALCOM XT55-GSC3
The XT55-GSC3 based on the XT55-
GPS module, is designed to be used
on any GSM network. This single and
very small (35 x 53 x 5 mm) compact
device, maintained features from the
predecessor XT55-GPS module from
Siemens, is a Tri-band GSM/GPRS engine
that works on the three frequencies
GSM 900/1800/1900 MHz, it also supports
state-of-art GPS technology for satellite
navigation.
The XT55-GSC3 is a combined GSM/
GPRS/GPS device that allows easy
upgrade of the performance of existing
XT55-GPS system solutions. The XT55-
GSC3 is designed for application
that prefers to use board-to-board
connection to the main PCB application
platform. The combination of these
three technologies in such a small formfactor
device will make many new
asset-tracking applications possible,
particularly in the fields of transportation,
logistics and security. This combination
concept builds the perfect basis for the
design tracking solutions for applications
such as fleet management, vehicle
tracking, navigation, emergency calling,
location-based services and others. It
saves significantly both time and cost
for integration of additional hardware
components.
The XT55-GSC3 incorporates 8 Mb of
FLASH memory.

XT55-GSC3
Applications
The integrated GPS
module provides more
than enough precise
location information using
satellite signals to enable
users to determine where
they are anywhere in
the world. For battery
powered applications,
XT55-GSC3 features a
charging control that
can be used to charge
a Li-Ion battery. The
charging circuit must be
implemented external
the module on your
application platform.
