2 Overview
2.1
General
The Fastrax UC530 is an OEM GPS Antenna Module with the Mediatek MT3339 receiver. The module has ultra
small form factor 9.6x14 mm, height is 1.95 mm nominal (2.25 mm max) and can be assembled with SMT reflow
soldering. The Fastrax UC530 receiver provides extremely low power and very fast TTFF together with weak signal
acquisition and tracking capability to meet even the most stringent performance expectations.
The UC530 provides complete signal processing from embedded antenna to host port UART and location data
output is in NMEA protocol. The module requires a main and a backup power supply. The host port is configurable
to UART during power up. Host data and I/O signal levels are 2.8V CMOS compatible and inputs are 3.6V tolerable.
The UC530 supports a new feature called AlwaysLocate™, which is an intelligent controller of the UC530 power
saving mode. Depending on the environment and motion conditions, the module can adaptively adjust the
navigation activity in order to achieve a balance in positioning accuracy, fix rate and power consumption; typical
power consumption varies between 2… 8 mW.
The module is also optionally self-assisted since the EASY™ (Embedded Assist System) ephemeris extension is
embedded in the software without any resources required from the host. The EASY™ data is stored on internal
flash memory and allows fast TTFF typ. 3 seconds over 3 days. Also EPO™ (Extended Prediction Orbit) server
generated extended ephemeris input is also supported, which allows fast TTFF 10 seconds typ. over 7/14 days.
The UC530 contains also an AIC (Active Interference Cancellation), which provides state-of-art narrow band (CW)
interference and jamming elimination up to 12 CW jammers < -80dBm.
The module also supports a logging feature called LOCUS, which enables automatic logging of position data to
internal flash memory. The logging capacity is >16 hrs typ. @ 15 sec storage interval.
The UC530 module supports also an external active antenna connectivity with excellent out-of-band blocking
rejection and which provides also 3V antenna bias supply and automatic RF signal path switching.

module.
