The Fastrax UC430 features an always-on location awareness that enables fast and convenient use of location aware digital devices. By utilizing SiRFaware technology, including the Adaptive Micropower Controller, the module autonomously activates itself periodically from stand-by, resulting in the reduction of Time To First Fix (TTFF) by up to 70 per cent. The SiRFaware technology allows the module to maintain hot-start readiness with minimal power consumption of 125µA average current and <10mW in TricklePower 1Hz navigation mode to ensure uncompromised battery life.

The self-assisted positioning feature is based on Client Generated Extended Ephemeris (CGEE), allowing the module to calculate predicted satellite positions for up to three days following the latest activation based on broadcast ephemeris data. The CGEE removes the need for expensive and time-
consuming data communication required to obtain traditional A-GPS information. The module has future support and connectivity to optional external sensors for dead reckoning, enabling the detection of more accurate static position and movement when satellite signals are unavailable.

The circular radiation pattern of the Fastrax UC430’s integrated chip antenna ensures signal acquisition. It also has a cold start acquisition sensitivity of -147dBm and tracking sensitivity of -163dBm that ensures high-performance navigation. In addition, the Fastrax UC430 contains an active jammer remover which tracks and removes up to eight interfering signals that would otherwise decrease navigation performance. It also supports an optional connectivity for external antenna signal, enabling the module to stay operational even if the external antenna is removed or damaged. The module supports both active and passive antennas.

Samples of the Fastrax UC430 are available at Rutronik now. The volume production of the module will start in the fourth quarter 2011.
