Fastrax has unveiled the Fastrax UC430, a combination of a complete GPS receiver and an integrated chip antenna packed in a miniature form factor.

Sized at 9.6 x 14.0 x 1.95mm including antenna, the low-power-consuming module is suited for handheld computers, digital cameras, mobile phones, asset-tracking devices and other applications with space and power restrictions.

The Fastrax UC430 maintains awareness of its location at all times, contributing to fast and convenient use of location-aware digital devices.

By utilising Sirfaware technology, including the Adaptive Micropower Controller, the module autonomously activates itself periodically from standby, resulting in the reduction of Time To First Fix (TTFF) by up to 70 per cent.

Sirfaware is able to maintain hot-start readiness with minimal power consumption of 125uA average current and less than 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 Fastrax UC430 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 the expensive and time-consuming data communication required to obtain traditional A-GPS information.

In addition, 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.

In handheld digital devices, antenna design and sensitivity must compensate for varying orientation.

The circular radiation pattern of the Fastrax UC430’s integrated chip antenna ensures signal acquisition, while the cold-start acquisition sensitivity of -147dBm and tracking sensitivity of -163dBm warrant high-performance navigation.

The Fastrax UC430 also contains an active jammer remover, which tracks and removes up to eight interfering signals that would otherwise decrease navigation performance.

In addition to the integrated chip antenna, the Fastrax UC430 supports optional connectivity for external antenna signal.

The option allows using the integrated antenna as a backup, enabling the module to stay operational even if the external antenna is removed or damaged.

The module supports both active and passive antennas.

Application designers benefit from easy integration and reduced development time.

The addition of serial connection, one control signal and power supply is all that is required to make the Fastrax UC430 operational.
