Fastrax UC324 OEM GPS receiver module

Click2Contact

Fastrax has introduced its UC324 OEM GPS receiver module, which uses the SiRF single-chip receiver GSC3LT having high navigation sensitivity of -159 dBm. The receiver provides low power 90 mW and very fast TTFF together with weak signal acquisition and tracking capability.

The module provides signal processing from embedded GPS antenna to serial data output in NMEA (or SiRF binary) messages. The embedded antenna has good radiation gain, which leads to solid GPS signal levels. The antenna operation is optimised for 50-110 mm ground plane width.

The device has no need for copper cut out under the module; rather it can be placed right on the ground plane. This feature allows easy placements of other components.

The module requires a single power supply VDD and it interfaces to the user’s application via one serial port.

The module is available in two versions: SiRF ROM code; and early samples are provided with embedded flash version (4 Mbit in GSC3LTf), which also allows evaluation with GSWLT3 firmware.
