Fastrax and SiGe team up for 'Software GPS'

4 March 2009 Telecoms, Datacoms, Wireless, IoT

Fastrax has selected SiGe Semiconductor’s SE4120 to power its Software GPS solution.

As a result of the collaboration, the Fastrax Software GPS and SiGe’s SE4120 radio frontend make available a high performance GPS solution, complemented with a reference design to enable easy integration by third parties. The reference design is also available as a turnkey solution in the Fastrax iT900 RF module.

This combined offering converts the GPS radio frequency (RF) signal into a digital intermediate frequency (IF) signal that is processed by Fastrax’ Software GPS solution. By deploying SiGe’s IC, Fastrax Software GPS solution can provide navigation sensitivity as high as -163 dBm.

While traditional GPS solutions require the integration of a GPS-specific baseband, a software-based solution can enable faster time-to-market with less costs and more adjustable features. With the Software GPS, functionality can be managed and customised for each specific device and application.

The Software GPS focuses on the optimisation of signal acquisition and correlation, the functions typically requiring the most CPU power and memory in GPS solutions. The solution’s inherent flexibility enables portability to a range of CPUs, specific application processors and operating systems, as it is based on the Fastrax iSuite architecture, which was originally designed for embedded environments.
