Fastrax UC430 GPS antenna module

The Fastrax UC430 with integrated chip antenna is a complete miniature positioning engine for handheld digital devices.

The low power consuming module is suitable for handheld computers, digital cameras, mobile phones, asset tracking devices, and other applications with space and power restrictions.

The device maintains awareness of its location at all times. By using SiRFaware, including the adaptive micropower controller, the module autonomously activates itself periodically from stand-by, resulting in the reduction of time to first fix by up to 70%.

SiRFaware can maintain hot-start readiness with minimal power consumption of 125 µA and <10 mW in tricklepower 1 Hz navigation mode to ensure long battery life.

The self-assisted positioning feature is based on client-generated extended ephemeris that allows the device 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 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 integrated chip antenna ensures signal acquisition, while the cold start acquisition sensitivity of -147 dBm and tracking sensitivity of -163 dBm warrant high-performance navigation.

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

In addition to the integrated chip antenna, it supports optional connectivity for an external antenna. The addition of a serial connection, one control signal and power supply is all that is required to make the module operational.
